Helps ingest data, enhances business resilience and problem-solving capabilities
Pros and Cons
  • "The two features I appreciate most in Splunk Enterprise Security are the content management system and the inter-incident review dashboard."
  • "They could offer pre-built search queries for everyday use cases like brute force attacks, DDoS attacks, and other security threats."

What is our primary use case?

I have created various correlation searches to develop use cases for detecting security threats. For example, I have created use cases to identify brute force attacks, unauthorized access, denial of service attacks, and distributed denial of service attacks. To date, I have developed a total of 190 use cases for our environment using Splunk Enterprise Security.

How has it helped my organization?

The end-to-end visibility provided by Splunk Enterprise Security is crucial. Its user-friendly interface makes it easy to navigate and configure. The intuitive options allow for simple customization, enabling users to easily select and configure settings. This feature, combined with the excellent support from the Splunk team, makes it a valuable tool for addressing enterprise security issues and creating or modifying use cases.

Splunk's website provides a variety of simple commands for identifying security events. These commands and pre-built security fields make it easy to detect real-time attacks, monitor environments, and identify security threats. Splunk offers a more straightforward and efficient approach than other monitoring tools.

Splunk automatically ingests and normalizes data, eliminating the need for human intervention. When data is ingested, it is automatically converted into index-friendly formats within most source pipes.

The MITRE ATT&CK framework is a valuable tool for security teams, and its integration with Splunk Enterprise Security offers significant benefits. By mapping specific MITRE ATT&CK tactics to Splunk use cases, analysts can quickly identify the root cause of security incidents and access relevant information for remediation. For example, if a brute force attack occurs, an analyst reviewing the incident can quickly determine the corresponding MITRE ATT&CK tactic and access detailed information about the attack, including potential solutions, mitigation strategies, and potential future actions. This seamless integration between MITRE ATT&CK and Splunk empowers security teams to respond to threats more effectively and efficiently.

Splunk has significantly enhanced my business resilience and problem-solving capabilities. Due to the urgency of different issues, there are four types of Splunk support cases: P1, P2, P3, and P4. P1 cases are incredibly critical and require immediate attention. If a business-critical issue arises, I can open a P1 case, and the Splunk support team will respond within 15 minutes. This rapid response has enabled me to resolve critical issues promptly. For P2 cases, the support team typically connects within two to three hours. P3 cases receive a response within 24 hours. Overall, the Splunk support team consistently resolves issues efficiently.

After deploying the use case, we immediately observed the benefits of Splunk Enterprise Security. We can instantly monitor enterprise security use cases in our environment without delay. However, as a precautionary measure, we deploy use cases and monitor them for seven days. If the use case does not generate excessive noise within this period, we deploy it to the final environment. Otherwise, we refrain from deployment. Splunk's capability allows us to deploy use cases within seconds.

Splunk helps me consolidate all the data, such as networking and cyber security data. If there are other types, such as behaviour analysis, we can perform them with the help of Splunk. But I'm mainly in the cyber security field, so I am more concerned with Splunk for cyber security data only. For example, in my PhD, I created my thesis based on medical performance monitoring. I monitor the performance health condition of one million people with the help of Splunk. So, this is not a cybersecurity use case I'm creating there. I monitor the health condition with the help of a Splunk Enterprise. If a health condition is significant, the alert immediately goes to the doctor, physician, and their relative.

My alert volume has decreased significantly. Splunk is a machine that generates alerts based on specific use cases or service queries. Before implementing a new use case or alert, we must analyze how many alerts it will trigger. If it generates fewer than one alert per day, it's acceptable. However, I will only deploy it if it generates one daily alert. This approach allows me to reduce the alert volume effectively using Splunk Enterprise Security.

Splunk streamlined my security investigations by consolidating logs into a single repository. The Splunk community provided invaluable assistance, enabling me to quickly find answers to my security-related questions and address concerns promptly. By leveraging the collective knowledge of the global community, I expedited my security processes and enhanced overall security measures.

Splunk reduces the mean time to resolve because it enables L1 SOC analysts to view relevant data in the power role field directly. For example, when a brute force attack alert triggers, analysts can easily see the source IP, time of the alert, user, destination IP, and other critical fields. This immediate access to information allows for swift preventive measures, countermeasures, and efficient resolution of cybersecurity issues. Splunk's clear and intuitive interface empowers even junior analysts with only one year of experience to effectively apply their knowledge and address security challenges.

What is most valuable?

The two features I like most in Splunk Enterprise Security are the content management system and the inter-incident review dashboard. The incident review dashboard allows us to directly view significant events triggered by the use cases I've configured within the content management system.

What needs improvement?

I suggest that Splunk provide the same resources on its platform, as on other websites through Google. For instance, they could offer pre-built search queries for everyday use cases like brute force attacks, DDoS attacks, and other security threats. These queries would be generated based on my specific data, saving me the time and effort of creating them manually. This would be incredibly beneficial and align with the AI capabilities already present in Splunk Enterprise Security.

For how long have I used the solution?

I have been using Splunk Enterprise Security for eight years.

What do I think about the stability of the solution?

In the eight years I have used Splunk Enterprise Security, I have experienced no stability issues. There has been no downtime or crashing. The only problems I have encountered were temporary interruptions in some features, lasting approximately 15 minutes.

What do I think about the scalability of the solution?

Splunk Enterprise Security is highly scalable. For example, I currently have one terabyte of data to deploy, and tomorrow, I need to deploy ten terabytes. In that case, the system can easily accommodate the increased load without compromising performance. It is extremely fast and efficient, ensuring no issues even as the input data volume grows. The system adjusts quickly to meet the demands of expanding data requirements.

How are customer service and support?

I have contacted Splunk technical support three times in the past fifteen days due to various issues encountered while using Splunk. Each time I reached out, they responded promptly and assisted me in resolving the problems.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have used several alternatives to Splunk, such as AppDynamics, Dynatrace, and Oracle Enterprise Manager. However, I have found Splunk Enterprise and Splunk Enterprise Security the most effective tools for my needs. These platforms are easy to use, allowing for flexible parameter customization and dynamic adjustments to meet specific requirements.

How was the initial setup?

The initial deployment of Splunk Enterprise Security was straightforward due to my prior experience learning and using various tools. I found it to be significantly easier to implement than similar software.

I set up my lab independently, being new to the environment at the time and eager to learn. I visited the Splunk website and discovered the free courses they offer. Using these courses, I successfully configured my lab. Splunk provides valuable assistance for setting up personal labs and offers a 60-day trial version. This version allows for direct log setup and hands-on practice of Splunk skills without cost.

What's my experience with pricing, setup cost, and licensing?

Splunk Enterprise Security's pricing is competitive. For instance, the cost typically increases proportionally with the daily license volume. For example, purchasing a 100 GB license per day is less expensive than buying one GB per day. A discount is offered for larger volume purchases.

What other advice do I have?

I would rate Splunk Enterprise Security eight out of ten.

Which deployment model are you using for this solution?

Improves our ability to handle data from applications
Pros and Cons
  • "Splunk's strength lies in its single-page view."
  • "Due to its high licensing cost, Splunk is out of reach for many organizations."

What is our primary use case?

As a Splunk engineer, I collect data from various sources, including Universal Forwarder, Heavy Forwarder, DB Connect, and Syslog to monitor application logs. This data is used to create dashboards that visualize application health and identify potential security incidents. Additionally, I configure alerts to notify teams via Slack or email when CPU or memory usage reaches critical thresholds, allowing for prompt resolution. Furthermore, I use Splunk to create KPIs and NDDs for various aspects of the organization, including a custom ITSI service for Microsoft 365. This service monitors child entities like Teams, Outlook, and Edge within a parent application, tracking metrics like team member logins and meetings, CPU usage, and memory usage. All this information is consolidated into a three-page ITSI report.

Splunk Enterprise Security helps us detect malicious activity, such as failed login attempts by unauthorized users. These attempts, whether brute-force attacks or phishing attempts, trigger alerts with detailed information about the incident mapped to the MITRE ATT&CK framework. This allows our security team to investigate and take appropriate action quickly.

How has it helped my organization?

We managed Splunk's large clustered environments, I oversaw data collection from roughly 750 applications via universal deployment clients. This experience, coupled with my nearly six years of Splunk expertise, made monitoring application logs and creating Splunk knowledge bases straightforward tasks. While processing task cut-off tickets from the application team could be time-consuming, the actual monitoring itself was easy to manage.

The end-to-end visibility provided by Splunk is important because our company uses applications like K-Connect and Splunk to monitor user activity across different sectors. Having previously worked in both healthcare and finance, I'm familiar with how this process works. We access user information including personal data to track their activity from start to finish within our systems. Splunk allows us to mark specific user data points for further analysis, ensuring we have a full view of user or patient activity within each organization we serve.

Splunk helps me find security events across multi-cloud and on-prem platforms. I would identify missing data by checking the last hour's timeframe (span=1h). If on-prem or cloud data was missing, I'd investigate which logs weren't being ingested, whether an indexer was down, or if a forwarder wasn't sending data. Additionally, I'd check if the application or event log volume was overwhelming the universal forwarder, requiring a queue to process the data effectively.

Splunk improves our ability to handle data from applications. This data is often unstructured or unavailable in a usable format. To make it usable, we used to normalize the logs manually through back-end commands and edit various Splunk consoles and platforms. This process transformed the data into a structured, human-readable event format, allowing us to extract the information we needed.

We can identify potential malicious activity through Splunk by analyzing database logs with SQL queries. For instance, a high number of failed login attempts within a short timeframe could indicate unauthorized access attempts. Additionally, with multi-factor authentication systems like Duo, a user logging in from two geographically distant countries within a short period might be suspicious. To address this, I've developed SQL queries that check for logins within a one-hour timeframe across different countries. These queries trigger alerts on a dashboard, allowing IT to investigate the user's IP address and determine if the login is legitimate.

Splunk has significantly improved our business resilience by providing a single pane of view for all our data. This visualization allows us to monitor for anomalies, including unusual application activity, unauthorized executables, and suspicious shell scripts running on both Linux and Windows servers. By triggering alerts for these events, Splunk empowers our organization to proactively identify and address potential threats, ultimately improving overall stability.

Splunk allows us to easily check the data for malicious activity. It also helps reduce the alert volume by allowing us to set thresholds for alerts. For example, we only receive an alert when the CPU usage exceeds 90 percent or the number of failed logs is more than 15.

Splunk helps us investigate by providing relevant context from system logs. We can search the Splunk logs for specific applications and timeframes, and then examine all the data fields for suspicious activity, failed login attempts, or any other anomalies.

It helps security teams investigate threats faster by providing a central platform to collect and analyze data from various security applications. This focus on enterprise security allows teams to identify and respond to threats across the organization, leveraging frameworks like MITRE ATT&CK to match attacker techniques and tactics.

What is most valuable?

Splunk's strength lies in its single-page view. This interface allows us to explore all our data, build dashboards with alerts, and visualize real-time information through various charts like column, bar, and pie formats, providing a full user experience.

What needs improvement?

Due to its high licensing cost, Splunk is out of reach for many organizations. Making their licensing more affordable would open up Splunk's solution to a wider range of users.

For how long have I used the solution?

I have been using Splunk Enterprise Security for six years.

What do I think about the stability of the solution?

Splunk Enterprise Security is a stable solution.

What do I think about the scalability of the solution?

Splunk Enterprise Security has excellent scalability.

How are customer service and support?

The technical support is good.

How would you rate customer service and support?

Positive

How was the initial setup?

The deployment is complicated  because our organization works with on-prem servers. All the data needs to be duplicated and all the searches and indexes need to happen properly.

What's my experience with pricing, setup cost, and licensing?

The Splunk licensing is high.

While more affordable, alternative SIEM solutions lack the flexibility and in-depth visualization capabilities offered by Splunk.

What other advice do I have?

I would rate Splunk Enterprise Security nine out of ten.

While Splunk Enterprise Security offers a user-friendly interface, its true power lies in its ability to create highly customized dashboards that streamline investigations and reporting.

Helps with the functioning of an organization's security operation center and to detect anomalies in data
Pros and Cons
  • "The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems."
  • "Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."

What is our primary use case?

The solution is used in my company to help the security operation center in work areas like detection, response, and investigation while maintaining cybersecurity standards.

How has it helped my organization?

My company has benefited from using Splunk Enterprise Security, which has helped us stay out of the headlines in newspapers. The tool helps detect threats early and respond to them effectively.

What is most valuable?

The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems. We need to be able to create insights that are indicative of malicious activities, which is one of the main purposes of having Splunk Enterprise Security in our company.

What needs improvement?

The product lacks cross-cutting capabilities. The features in Splunk Enterprise Security that were initially promised to our company are still not available. My company has been asking Splunk for some of these features to be provided in the product for years, and we have been promised that they will be introduced soon in the solution and be part of the product's next release.

I believe that the contract and the terms and conditions mentioned in it are areas where improvements are required.

For how long have I used the solution?

I have experience with Splunk Enterprise Security.

What do I think about the stability of the solution?

When it comes to the on-premises version, the stability of the product was quite reliable. When my company moved to the product's cloud version, we faced some major issues related to availability and dealing with events like data corruption.

What do I think about the scalability of the solution?

The product's scalability is okay. I do not think my company faced issues in the area of scalability.

How are customer service and support?

The product's support services were not great initially, but now they are in really good shape. Whenever my company connects with the product's support team, they listen to our questions and queries, so I feel that we are in a much better place now. I rate the technical support as eight out of ten.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

My company has experience with ArcSight. We switched to Splunk Enterprise Security because we couldn't get good answers to our questions from ArcSight, and it was just not functional.

How was the initial setup?

The solution is deployed using the cloud services offered by Splunk. Recently, my company also deployed the tool on an on-premises model. In our company, we monitor both, cloud and on-premises, with our cloud instance.

In the beginning phase, I would describe the deployment experience as a costly and hard process. The migration process from on-premises to cloud was hard and took our company a year to complete. There were different kinds of roadblocks on our company's and Splunk's end. My company worked directly with the migration process associated with the product.

What was our ROI?

It is difficult to say whether I have seen an ROI since it is like trying to figure out how much an insurance policy works. I think that our company will receive a return on investment from the use of the solution since it helps the organization's cybersecurity team stay out of the newspapers. My company has always been able to deal with threats quickly with the product.

What's my experience with pricing, setup cost, and licensing?

Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk. Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team. I like the direction Splunk stays in by thinking with the customers about how to reduce costs and only have that data searchable or available, which you need at a particular time. I like the path Splunk is going on, specifically its current trajectory. I appreciate the efforts put in by Splunk in the area partnership, which is what my company expects.

Which other solutions did I evaluate?

My company uses Microsoft Sentinel. A multi-SIEM environment provides my company with the best of both worlds. Sentinel has some good features, like Microsoft Graph Security, that the tool uses for the whole Microsoft ecosystem. Microsoft Sentinel is a good option for my organization.

In my company, Splunk acts as a product that complements Sentinel because the former lacks some features. I think Microsoft is strong in the area of service delivery. Microsoft's EDR tools, like Microsoft Defender, use Servers from Microsoft Graph Security, and my company benefits from such a type of integration, and we are able to send alerts to Splunk. In our company, if we start to ingest all the data we usually ingest in Splunk by moving to Sentinel, it will become too expensive, so we have to choose where to keep our data.

What other advice do I have?

My company has been able to reduce the mean time to resolve with Splunk Enterprise Security as it went down from a couple of days to hours.

My company has seen a significant reduction in alert volume. It was very noisy earlier, but lately, my company hardly sees any false positives.

It is super important that the solution provides end-to-end visibility of our company's environment because you can never know from where threats can materialize. The fact that users can correlate and ingest data makes sense and is crucial, considering the massive amounts of data.

Splunk Enterprise Security has helped improve our company's ability to ingest and normalize data, which is one of the tool's key benefits.

I would not say that Splunk Enterprise Security has helped solve problems in real-time scenarios, but it has helped solve problems on a near real-time basis. In my company, there is always some lag between the data that comes in and the ones being ingested and correlated. Splunk Enterprise Security aids in solving problems in a matter of minutes.

Splunk Enterprise Security provides relevant context to help guide our company's investigations, and it is very important and can be considered everything for our organization. In our company, we pull in data from assets and registries to give index-based alerts and be able to find owners quickly to notify them and respond to threats.

Splunk Enterprise Security's ability to help our company find any security events across environments is excellent. My company is really happy with Splunk Enterprise Security. The product helps our company find bad stuff when needed.

The truth is that it is very hard to deliver solutions that work at a certain scale. I think that one of the things I could say is that it is a solution that scales up at work. There are many organizations where solutions fail, and I can say that since I have been a part of the deployment of many other tools, it is hard to get many products to work. Splunk Enterprise Security works, and our company's analysts rely on it and trust it. I can only see improvements considering the strategies in terms of where the product's management team is going, and I believe that I will be able to rate the tool a nine out of ten pretty soon.

I rate the overall solution an eight out of ten.

Fantastic tool that we couldn't do our work without
Pros and Cons
  • "It has increased our business resilience. It's a top-of-the-line SIEM security product. It's the best tool for our security analysts which helps them do their job better. That then protects our company from adversary actors."
  • "I've never had too many issues with the stability. Years ago we had indexes crash but that was more on us. We didn't understand how to properly size Splunk."

What is our primary use case?

Our use cases are mostly for security and detection, basic use cases. It's always been a security use case. We never used it for observability or ITSI. 

Our analysts use it a lot.

What is most valuable?

I like that it's a review panel, you can see all of your alerts. Another valuable feature is that it integrates with other apps like UBA and SOAR. 

I also like the guided alert creation. The guided alert creation is useful, especially for new people who don't know CPL. 

It's a premium app, it's easy to use and intuitive. 

Enterprise Security has one pane of glass for all of our alerts. We still use the Enterprise Security page where we keep track of everything. 

It's very important to us that Splunk offers end-to-end visibility into our environment. It has the ability to identify any security events or if data is reingested, we'll get an alert for that. End-to-end visibility is very important for a mature security program.  

Splunk helped to ingest and normalize data. Anytime that we put data in, we always normalize the SIEM model. ES runs off of that so it helps us to dot our I's and cross our T's. It helps us to use our data effectively.

It has tools to reduce our alert volume. We get a lot of alerts. It's more of a tuning thing than anything that the app can help with. 

It provides us with the relevant context to help guide our investigations. It's really useful in that aspect. 

It hasn't reduced our MTTR. SOAR would do that. It has helped our mean time to detect. 

It has increased our business resilience. It's a top-of-the-line SIEM security product. It's the best tool for our security analysts which helps them do their job better. That then protects our company from adversary actors. 

What needs improvement?



For how long have I used the solution?

I have been using Splunk Enterprise Security for about five years. 

What do I think about the stability of the solution?

I've never had too many issues with the stability. Years ago we had indexes crash but that was more on us. We didn't understand how to properly size Splunk. If you work within the required parameters, it's stable. 

How are customer service and support?

Their support is great. I've never had any issues with them.

How would you rate customer service and support?

Positive

How was the initial setup?

The setup was pretty straightforward unless you add a search head cluster. Then it becomes a lot more complicated very fast. Other than that, it's not too bad. It's pretty simple and intuitive. I've done it before and it's not difficult especially if you have the docs to help you. 

What was our ROI?

I can't speak to the dollar amount but we see ROI in the way that it helps the analysts to better do their work. It helps keep track of things and having one pane of glass for all things data. 

What other advice do I have?

I would rate Splunk Enterprise Security a nine out of ten. It's a top-of-the-line product. It allows analysts to do their jobs better. It's a single pane of glass. It's a fantastic tool that we couldn't do our work without.

Reduces MTTR, improves efficiency, and centralizes everything
Pros and Cons

  • "Splunk Enterprise Security provides us with the relevant context to help guide our investigations, but it would be interesting to add even more context, for instance, in order to raise the level of risk."

What is our primary use case?

Our SOC is using Splunk Enterprise Security as a SIEM. There are multiple use cases because it is the main tool for SOC analysts. We have plenty of use cases. It is being used for IT security monitoring. We also have some custom use cases for securing applications, and then we have some of our internal customers developing their own use cases, but the main purpose is for the SOC. 

We also have additional work that is much more tricky. It is related to using AI to detect insider threats.

How has it helped my organization?

We are incredibly increasing our coverage as per the NIST framework that we are using for our operations. We are always extending. That really took off after implementing Splunk. It was a big moment. I have been there from the very beginning when we started implementing Splunk. Like everything new, there was a little bit of difficulty, but after we implemented it, there was an incredible increase in our SOC efficiency.

Splunk Enterprise Security helped reduce our mean time to resolve based on my knowledge, but I do not know how much because I left the department one year ago. On the security monitoring side, we have very good MTTR globally due to Splunk and the processes that we have implemented. We have other kinds of tools. Compared to the other tools that we have, our MTTR is far better with Splunk. Compared to last year, it was reduced by half. It was already good, but it got reduced a lot again.

What is most valuable?

It is lovely to have everything we need in one tool. Everything is quite centralized.

What needs improvement?

AI is everywhere, and I feel we need to discover AI for cybersecurity. For the last five years, I myself have been setting up a product and evaluating AI, but I did not do it directly in Splunk because there was some fear about the performance on the platform. That is why we chose to build our own platform based on S3 and AWS to execute and run all the algorithms and send the data back into Splunk. We now have a good base with innovation. We have a better base to directly include machine learning use cases in Enterprise Security, but they need to provide more capability and autonomy to the customers because there is so much to do. When you are lucky enough to have a team of data scientists, they want to have free hands, so a balance has to be found between giving a lot of autonomy and putting enough control so that they do not do something stupid on the platform, which can impact the performance of the standard use cases as well. There is a compromise there. However, AI is growing so fast that you absolutely need to give autonomy to the team to manage and utilize AI. This means providing easy access to a new library to build machine learning. They need to give us some flexibility, and it seems that with the new toolkit, it would be okay. Data scientists love to have freedom.

Splunk Enterprise Security provides us with the relevant context to help guide our investigations, but it would be interesting to add even more context, for instance, in order to raise the level of risk. That is something that can be implemented. For instance, when it comes to data loss prevention, it is known that somebody who is about to leave the company is much more likely to take data. If you have this information soon enough, because the person will tell HR in advance, you can increase the level of risk for data loss for that user, but you do not always get to know that in advance. In such cases, some indicators in the behavior of the users who are leaving could be connected to AI. For instance, if you are using natural language programming, you can grab emails with words like farewell. There are plenty of keywords that you can catch that would give you an indication that the person is about to live. When you have internal and external partners, they can leave at any time. You do not always get the information in advance, but there are always farewell parties or goodbye emails. You can use this kind of information to raise their risk on the specific alert. It is efficient in the sense that you decrease your false positive rate. To me, AI is something that can help them accelerate and improve on what they are already doing.

Splunk Enterprise Security is very costly. Pricing is probably its weakest spot.

For how long have I used the solution?

I have been using Splunk Enterprise Security for five years.

What do I think about the stability of the solution?

It is difficult for me to answer this because I am no longer in charge now, but it has been stable from my point of view. 

What do I think about the scalability of the solution?

Its scalability is good provided you have the right license agreements.

How are customer service and support?

It depends on the situation. The problem at our end that is causing an issue with Splunk support is that we have a customized environment. All the problems that we submit are specific, and they can be a bit difficult to solve. Sometimes, their support is efficient, and at other times, we have to wait a bit too much. I would rate their support a seven out of ten.

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

I arrived at the time of transition. We were probably using RSA. We switched to Splunk Enterprise Security because we needed to jump to another scale. At that time, there was a complete change in the organization. We went from the old-school cyber to Cyber 2.0. We had a lot more visionary managers who came from other companies where they were using Splunk. We had good guidance.

How was the initial setup?

It was a bit difficult. The team that was developing the use cases did not have access to the real data because it was not ready yet. Developing a SOC use case without the data is something difficult. That is why it was difficult at the start, but it was not because of the tool. It was more of a matter of project management. After we moved on from the difficult stage, we were able to set up this use case factory where some of the users were themselves in a bit of self-service mode. This was a very good opportunity to enlarge our capability to cover all the applications in the best way.

For Splunk, we use AWS. We have a private cloud. We have difficulty using cloud-managed services.

What's my experience with pricing, setup cost, and licensing?

Pricing is probably its weakest spot. As compared to some competitors, Splunk is really expensive. The problem is that Splunk is like Rolls-Royce. It, for sure, is the best one. Gartner says it, and the customers say it, but sometimes, you do not need a Rolls-Royce to get to the supermarket.

The problem is that the licenses that we have are based on the volume of data that we ingest in a day. The data that we ingest is only growing. We have initiatives right now for better management of data. It makes sense in terms of storage and sustainability. The pricing model, especially for Europe, is difficult. I am just out of the negotiation for the renewal of the license. We bought it for three more years. This is good news for Splunk and us as well, but it was difficult to discuss with the sales and explain that we do not want to increase the cost because it is already too high, and if it could decrease, it would make sense. It is very difficult to have this understanding from the salesperson. It was difficult for my Splunk account partner, but we succeeded in the negotiation. It was a win-win situation.

They need to be fair and adjust the price as per the usage. If the price goes too high, we would just have a no-go from the top level of the company, which would be a pity. It can happen. It has happened in the past. At some point, we had a big contract with Microsoft for Office, and we are now with Google. It was a shock for the partners and people inside the company, but we did it. We now have Google and we are happy with it. We still have a bit of Microsoft. It is important to keep the balance.

We are looking at the data usage with Splunk's team. We are looking at whether the data onboarded and dashboards that were developed are really being used to avoid wastage. If any data is not necessary in Splunk, we just stop onboarding it. We have other data to onboard anyway. My idea is to be much more efficient in the way we are managing the data and not to go the way we did it in the past.

Which other solutions did I evaluate?

I did not evaluate other solutions but the company surely did.

What other advice do I have?

Splunk's unified platform has not helped consolidate networking, security, and IT observability tools, but it is not due to the tool. It is due to our company's structure. I have been part of the two teams. Previously, I was a part of the cybersecurity team, so I was mainly using Splunk Enterprise Security. Now I am leading the monitoring team, so I am much more on the SOC side of it. My team provides service to the cybersecurity team that is using Splunk Enterprise Security. In the end, we would like to have one solution, which would be Splunk. I would like to have IT monitoring and observability with ITSI in the future. This centralization would bring efficiency. One log being used for cybersecurity purposes can also be used for other purposes. Everything centralized would give us the most efficient way to access the data and limit duplication. It would be helpful for efficiency, cost control, and data governance.

It is absolutely crucial for us to have end-to-end visibility. For our cybersecurity needs, we should be able to reach anything. We even have this concept of Watch the Watcher, so visibility is absolutely key. We have the opportunity to audit the activities of even cyber analysts, so visibility at every stage is absolutely key. For example, all the SIEMs could be under attack, which would be a nightmare. Imagine it being an insider threat where the attacker knows what exactly we are monitoring. With AI, these kinds of risks are even higher. That is why we are all in for AI for Cyber and Cyber for AI. We need absolute visibility, but we also need protection.

Splunk Enterprise Security has not helped us reduce our alert volume. We are not at that level of maturity at this point. It is still growing.

I would rate Splunk Enterprise Security a nine out of ten. It is a good product. It needs some progress with AI, but based on what I have seen in the presentation for version 8, it seems promising.

Gives visibility into what's happening across the network and allows us to dig deep
Pros and Cons
  • "Being able to aggregate detection and alerts from various sources is valuable. Like everyone else, we have a wide range of tools in our shop. We are able to stop at one spot and look at all the data. All the data is able to come through, and we can then jump from source to source or index to index. We can dig deep whenever we need to and get a good high-level understanding."
  • "The first thing that comes to mind is a little bit of UI improvement. It sometimes can be a little bit buggy or it can be a little bit slow, but that varies from customer to customer."

What is our primary use case?

I am a SOC lead, and we use Splunk Enterprise Security for alerting and working on incident review and incident response.

We have a hybrid environment. We have multiple clouds, and I am not sure if I know all of them. We have Azure Labs that we run for our students. We have cloud infrastructure. We have cloud applications on which we need visibility.

How has it helped my organization?

It is incredibly important that Splunk Enterprise Security provides end-to-end visibility into our environment. Especially being someone who goes through and reviews the work that my analysts are doing, I definitely need to be able to see what is happening all across different domains of our network.

We work for a large university, and we have different tenants. We have our students, we have our employees, and then we have our faculty as well. We definitely need to see what is happening across the domains and across all of those different tenants.

It saves so much time for the analysts, and it empowers analysts to carry out and triage an investigation, wherever needed. It is incredibly hard when you are working with different sources. I am sure everyone else knows that you cannot expect your analysts to be on the same page a hundred percent at the time. They might say, "Hey, I am going to go into this tool and look at these alerts here, or I am going to look at these learnings from this tenant." We need to be looking at all of those sources and all of those domain tenants at once. Being able to see that across the board and not having to jump through hoops to get the data that we want is extremely valuable. I do not have metrics for how much time it has saved because I do not know our life before Splunk. I know that it has done a great deal in saving time, and now with SOAR, that is exactly what we are looking into. We are looking into how we can empower that even more by combining it with Splunk Enterprise Security.

Splunk Enterprise Security has helped improve our organization’s ability to ingest and normalize data. Splunk is definitely a leader. I cannot imagine leaving and going to another toolset and losing the capabilities that I have and the knowledge that I have. One of my favorite parts is that Splunk really does work. It seems to me that they work with actual users on a regular basis, so they know the pain points and they know what our issues or our primary concerns are.

In the beginning, it did not help to reduce our alert volume, but over time, it has definitely reduced that. Something that I am working on primarily with our SOC right now is increasing our alert volume because we are at such a low rate because of the work that we can do with Splunk's capabilities. We are looking into what areas in the network we are not alerting on. We have these out-of-the-box solutions, but there is more that we can build on. It is empowering our analysts to be SOC analysts, but the more advanced employees can work towards the threat detection engineering side or SOAR playbooks development side or even just on the backend of setting up and working with the configuration.

I wish I knew the metrics for the reduction in the alert column. I do not have any approximation, but our SOC is very manageable. We are a small team, and the number of alerts varies. On average, we get about 300 alerts a day on the high end and 150 alerts on the low end. If it is a very slow day, such as a vacation for everyone, and we do not have a lot of activity going on in the network on our endpoints, it is very manageable for a small team. Our SOC team has four full-time employees, and then we have intern/student workers because we partner with the university. We have three of them. Overall, there are seven, but, of course, students are only able to work a maximum of 15 or 18 hours a week or something like that, so the amount of man-hours that we have is pretty low.

Splunk Enterprise Security provides us with the relevant context to help guide our investigations. There could be a little bit more, but that also depends on the analysts and where they are in terms of maturity. I have a lot of capability to go and expand what I need to, but others do need a little bit more guidance. It is not easy on the first look for someone who has never done it before, but after being taught or learning about it themselves, it is pretty easy. It can still do a whole lot. If we are looking at an anonymous login, we are getting context from different sources. If there is an activity that is going on in the host machine, such as we have some login from Russia, which has never happened before, there is a firing of alerts from the EDR. We can see our email gateway firing alerts regarding their account. That allows us to contextualize and correlate the activity very easily.

Splunk Enterprise Security has helped improve our organization’s business resilience. We are able to take action immediately when we need to. Especially with risk-based alerting, we are able to understand what needs attention right now. We do work with young junior analysts a lot, and we are able to teach them how to identify what needs action right now or what needs to be investigated or triaged immediately. We are basically protecting our crown jewels first rather than some low-hanging fruit that we see everyday, but we cannot take a look at them because we have some important things going on in our network.

What is most valuable?

Being able to aggregate detection and alerts from various sources is valuable. Like everyone else, we have a wide range of tools in our shop. We are able to stop at one spot and look at all the data. All the data is able to come through, and we can then jump from source to source or index to index. We can dig deep whenever we need to and get a good high-level understanding.

What needs improvement?

The first thing that comes to mind is a little bit of UI improvement. It sometimes can be a little bit buggy or it can be a little bit slow, but that varies from customer to customer.

They can continue building out the Splunk community. They can give incentives for customers to collaborate and expand on what they are working on but also provide the tools to do that. There are good resources such as Splunktern. I love the Splunk education and training platform. It is amazing, but I wish there was a little bit more. Especially with the training and applications, they should give us real-world use cases and a little bit more specific scenarios. Splunk is doing a much better job than a lot of other organizations or technology platforms, but they can give more information. I know a lot of my Splunk users do not even realize the things that they can do. On the user end or analyst end, they need to be more proactive by giving more of a heads-up. For example, I found out about Splunk research today. I have been using Splunk for two years. I wish I had known about that more. They can reach out more. The incentives can be anything. Some people love stickers, and some people love shirts. They can create that community a little bit more.

For how long have I used the solution?

I have been using Splunk Enterprise Security for two years.

What do I think about the stability of the solution?

I do not have much to compare it to, but it is stable. We hardly have any issues, and if we do, they are intermittent. 

What do I think about the scalability of the solution?

The growth that we have seen in my time with our team has not been so much. However, we are adding more tools or trying to gain visibility into different areas of our network or applications that have already been there. Being able to throw some logs in and figure out that we should be monitoring this has been painless. We can just forward them all over. It takes an hour or so. We get the answers and the visibility that we need.

How are customer service and support?

I have not used it very often. I have used it once or twice, but I would say that the engineers I have worked with have been extremely knowledgeable. They have helped so much. We were working on SOAR, and we were pretty new to it as a SOC. We were able to work all of that out with a Splunk engineer on a call. They were able to answer our questions. They knew our needs and goals, and they were able to guide us to meet those. That has been very effective for us. I would rate them a ten out of ten. I have not had any bad experiences.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We have had Splunk since I have been in this company.

What was our ROI?

Specifically, I cannot say what return on investment we are getting. However, when we look at other products, we know we are not going to have the same capabilities and we are not going to have the same response times and correlation capabilities. Even working with other vendors and getting their logs into Splunk can be a nightmare, and that is enough to make us say that we do not want to buy their product.

Which other solutions did I evaluate?

Personally, I have not evaluated other solutions. We do have some friends and family connections who use other solutions. Based on their stories, we will continue using Splunk.

What other advice do I have?

I would rate Splunk Enterprise Security a nine out of ten. If it were a ten, it would do my job for me.
