The solution has improved our operations by giving us access to more information and allowing us to deploy more use cases
Pros and Cons
- "Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
- "The monitoring aspect of Splunk could be improved. We have to do some queries to get as much information as CrowdStrike or other solutions provide. If you run a big query, you will see a delay. That is the only concern we have because it will take some time if you query large data sets."
What is our primary use case?
How has it helped my organization?
Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases. We have integrated Splunk with ServiceNow, so the information from the queries running on the back end is now directly forwarded to the analysts, reducing the manual work. We are pulling data from Splunk into ServiceNow, so the security analysts have all the user details to conduct their investigations.
What is most valuable?
It's easy to monitor multiple environments with Splunk. The cloud model is better than the previous on-premises version. The custom dashboards are helpful. We have created multiple dashboards for user activity, logins, phishing, etc. If you miss an alert, you can check the dashboards. For example, if you need to check some user activity, we have a dashboard for Azure Active Directory, and Mimecast is integrated for monitoring email-based attacks like phishing. It throws the information up on the dashboard when we get an alert.
What needs improvement?
The monitoring aspect of Splunk could be improved. We have to do some queries to get as much information as CrowdStrike or other solutions provide. If you run a big query, you will see a delay. That is the only concern we have because it will take some time if you query large data sets.

The search feature is fast and comprehensive
Pros and Cons
- "I like the search feature and the indexing. It's very fast and comprehensive."
- "Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs."
What is our primary use case?
We use Splunk for log analytics, blocking dangerous files, etc. It helps to shape our security policies. Splunk is managed by our service provider, but we regularly get security insights from them.
What is most valuable?
I like the search feature and the indexing. It's very fast and comprehensive. It's easily tuned by your service provider, so I can quickly find the results I'm seeking. So it's very practical. We are working with the search feature and using multiple indexes that combine devices from different environments, so it's easy to collect information across environments.
We can relatively quickly detect some malicious activities based on attack patterns and implement use cases configured by our service provider with help from Splunk. It improves the speed of threat mitigation because you can gather information about the attack patterns from a few days of online activity to block threats and take the necessary actions.
For how long have I used the solution?
We implemented Splunk at the end of 2020, so it's been around three years.
What do I think about the scalability of the solution?
Splunk Enterprise Security is scalable.
How are customer service and support?
We have not been in direct contact with Splunk except for a workshop where I met a few of them. My impression was that they were skilled, experienced experts. They seemed helpful, so I had a good impression.
How was the initial setup?
The service provider deployed Splunk, so I wasn't involved. I had heard that they experienced some difficulties setting it up, but I don't think it was harder to install than other solutions.
What's my experience with pricing, setup cost, and licensing?
Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs.
What other advice do I have?
I rate Splunk Enterprise Security eight out of 10.

Practice Head-CyberSecurity at ALTEN calsoft Labs
Good support with an intuitive dashboard but the cost is too high
Pros and Cons
- "The most valuable aspect of the solution is the dashboard. It's very intuitive."
- "There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side."
What is our primary use case?
Since we have an IT services company, we have been using Splunk for the deployment to the customer locations as well. Sometimes the customer will come back to us and say that we need to have a SIEM tool, and when we do the benchmarking, we'll do a couple of deployments on the Splunk side and at the customer's locations as well.
As an example use case, we deployed Splunk to a banking institution a few years ago. There the use case was basically this: the customer wanted to set up a security operation center, and they wanted to have a pretty large deployment in terms of the number of endpoints and number of switches and routers. There were many regional branch offices and they have data centers and therefore, many assets in terms of endpoints. They had 30% of their assets are running on the cloud and they needed a complete solution from an incident monitoring and management perspective. That's why we deployed Splunk.
They wanted to reduce the MTTR, and meantime resolution, and maintain detection. They didn't want to add more SOC analysts into their SOC as the organization scaled up. They have a plan to scale from 5,000 endpoints into 15-20,000 endpoints. They're very particular about deploying the SOC operation center.
Splunk has since acquired Phantom as a SOAR platform. Therefore, we have tried to manage the security automation using Phantom with the help of Splunk deployments. It helps us meet the customer's requirements.
How has it helped my organization?
In terms of support, we're able to get the right support at the right time. If there's a break or an appliance issue, they're are on top of it.
This is very important during large-scale deployments. It's not easy to address product-related issues or appliance-related issues, and the number of collectors or number of logs that come into the collector, and managing the collectors across the branch offices, across the corporate offices, etc. It is a cumbersome process for us. That's why it's integral that we get the right support at the right time - and they make this happen.
What is most valuable?
The most valuable aspect of the solution is the dashboard. It's very intuitive.
The reporting is excellent. The team and the SOC analyst are able to easily track the alerts and the correlation is very good compared to other SIEM tools.
What needs improvement?
There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side.
The automation could be better. Typically, the issue that we face is that it has to go to the analytics engine, then goes to the automation engine, basically. Therefore, if there are no proper analytics, the SOAR module is going to be overloaded, and we are not able to get the expected result out from the SOAR module. If they improve the analytics, I think they'll be able to solve these issues very quickly.
The playbooks which they create and provide to premium users can improve a lot. They have to create a common platform wherein the end-customers like us can choose the playbooks, and automation playbooks readily available.
In terms of integration with the third-party tools, what we are seeing is that it's very limited compared to the competitive products. Competitive products have a lot of connectors and APIs that they have developed, and that's where the cloud integration, whether it is a public cloud or a private cloud integration comes in. There are a lot of limitations to this product compared to other products.
For how long have I used the solution?
In terms of Splunk, I've been working on it for more than three years in the current company. Prior to that, I worked with it at another company as well. In total, I have been using Splunk for close to six or seven years.
What do I think about the stability of the solution?
The solution is stable, however, sometimes in some of the collectors, we are facing a lot of issues. That said, overall, if you rate it from one to five, I would say in terms of stability, it will stand at a three.
What do I think about the scalability of the solution?
The scalability is perfectly fine. It's very awesome compared to all the other tools, as easily we can integrate with the log forwarding modules and the collector management appliances or modules. That aspect won't be a problem.
If you look at the SIEM as a market today, Splunk is expensive compared to other competitive products. I'm also into the SIEM evaluation in my current role. I've seen that there are many tools are coming up in the last one and half years. I have also seen many other mature tools that are available now. If you compare next-gen SIEM tools compared to the Splunk, it's expensive. Therefore, it's possible we may not use this in the future or expand on current usage.
How are customer service and technical support?
In terms of technical support, we don't have any issues, as the professional services which they have extended to us are very, very good. We're able to manage many of the critical issues with their support. I'd say we are definitely satisfied with the level of service provided.
How was the initial setup?
In terms of deployment, it's not so complex compared to the competitive products, however, we will be able to manage that deployment. We don't feel there's any problem on the deployment side. In that sense, I don't think deployment is a complex one when somebody going for Splunk as a tool.
How long it takes to deploy the solution depends on the size of the deployment, basically. Even a large deployment won't take more than a week. When I say deployment, I'm considering all the log collection, log management, and the curation of the incidents, and how incidents are created and routed properly according to prioritization.
What was our ROI?
In terms of ROI, for example, if you look at one of our customers today, they are managing close to 100 million events per day. If you look at a traditional SIEM with 100 million events, they need to manage this environment with at least 25 to 30 people. That's 30 security analysts that have to be there. However, when Splunk was deployed, a lot of automation was added on top of it, and today we are managing the same environment with Splunk with close to 15 people. In that sense, if you look at it that way, the ROI is between 30-40%.
What's my experience with pricing, setup cost, and licensing?
In terms of a comparison with the rest of the competition, the licensing cost would be, I would say, 30% higher than most.
Which other solutions did I evaluate?
Before choosing Splunk, we have evaluated QRadar and LogRhythm. QRadar is much more expensive. LogRhythm lacked reporting.
We ended up choosing Splunk due to the pricing and the reporting features. It also had the kind of scalability that was required. We felt it would help us in terms of positioning from both a cost perspective and an incident alert perspective.
What other advice do I have?
We're partners. We have a business relationship with Splunk.
We're using the latest version of the solution.
Overall, I would rate the solution at a seven out of ten.
I'd advise potential new users to ensure they do proper sizing before deploying the product. If it's a very large deployment, the number of endpoints will be quite sizeable. You need to figure out the correct number of endpoints as well as endpoint devices, switches, routers, etc.
It's also a good idea to look at use cases. Splunk is very strong in some use cases. It's important to look into deployment scenarios and check out the use cases before deploying anything.
My biggest takeaway after working with the solution is that the environment is very important. You need to be clear about the problem you are addressing and it takes a lot of planning at the outset.
Which deployment model are you using for this solution?
On-premises

Principal Cyber Security Engineer at a financial services firm with 5,001-10,000 employees
Provides users with insights and the ability to send alerts to analysts
Pros and Cons
- "The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
- "I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team."
What is our primary use case?
I mostly use the solution in my company for incident response, ticket management, and integration with other endpoint products.
How has it helped my organization?
The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers.
What is most valuable?
The most valuable feature of the solution is the correlation searches. The one-stop shop shows me all my insights, and alerts, and can send alerts to my analysts.
I would say it is fairly important for my organization that Splunk Enterprise Security provides end-to-end visibility in our environment. At the same time, my company has other products that cover the observability piece. From a security perspective, we use data outside of our security data to piece together the whole picture. I think our company's perspective is that no matter how we get the whole picture, we will do it, even if it is from outside Splunk Enterprise Security. I think Splunk Enterprise Security plays a major role in this.
In terms of Splunk Enterprise Security for helping our company find any security event across multi-cloud, on-premises, or hybrid environments, I would say that it is great once you get past the learning curve. The learning curve is higher than normal.
I think Splunk Enterprise Security has helped improve our organization's ability to ingest and normalize data in a great manner. Splunk is a great product and provides these features, but not so much when it comes to identifying and solving problems in real-time because there are always data delays. There is always onboarding, mapping, creation of correlation search, and then enabling Splunk ESCU part. It works in a general sense and not on a real-time basis.
In terms of whether Splunk Enterprise Security has helped reduce alert volume, I would say that it is the only active SIEM tool my company is currently utilizing. Reducing alert volumes involves tuning up certain areas of the engineering team. If I look at the product alone, I would say it can help reduce alert volume. If I consider the learning curve, I would say that you have to learn how to tune it the right way with the help of professional services or experts. You need to utilize your resources, which I think is the best way to do it.
Splunk Enterprise Security provides our company with relevant context to help guide our investigations since the correlation searches with the enriched data do help gain insights on all of our investigations. At the current point, we are still trying to get past the tool's learning curve so that all of our analysts and everyone on the security team can utilize the tool the best way they can. The more they learn, the better it gets, so currently, we are doing our best.
Splunk Enterprise Security helped reduce the meantime needed to resolve our issues because we have all our data in a centralized location and mapped to a data model. As long as we know what detection and data we are looking at, we can go to our data model and figure out where the issue lies.
Splunk Enterprise Security's ability to help improve our organization's business resilience revolves more around observability. Our company recently migrated to Splunk Cloud, and I think we have more hands-on experience with the ingestion side than ever before. I think it is a lot easier for us since we moved to Splunk Cloud as we don't have to focus on maintaining the infrastructure so much, and we can focus more on the data. I think this is outside of Splunk Enterprise Security's scope and falls under Splunk Cloud's capacity.
Speaking about Splunk's unified platform helping consolidate networking, security, and IT observability tools, I would say that my company is not there yet.
What needs improvement?
In the next release, I want Splunk to offer more openness to integrations with other products that may be more of a preference for my incident response teams.
For how long have I used the solution?
I have been using Splunk Enterprise Security for five years. I am an end-user.
What do I think about the stability of the solution?
In terms of stability, if configured correctly, it works great.
What do I think about the scalability of the solution?
With Splunk Cloud, I think using the tool's scalability feature is easy since one can just call the product's support team.
How are customer service and support?
The solution's technical support is great since they have been very responsive and very attentive while answering all my questions. If the support team can't answer my questions, they escalate it to their engineering team.
I have had nothing but good things to say about Splunk's technical team. There have been times when I had to rephrase my questions or when there were communication issues, but the time to respond, escalation, and the attempts in trying to find help and answers from the support team's end have always been great.
I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team. If this process is the only way I can find answers, I think it is a little bit limiting for an engineer who supports a real-time incident response team. I rate the technical support a nine and a half out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have personally not used any other product before Splunk Enterprise Security.
How was the initial setup?
The product's deployment phase was pretty easy to manage since our company has a migration team and support staff. We also had a really good project manager from Splunk to help us, who walked us through every step, and it was a great experience.
The solution is deployed on Splunk Cloud, which runs on AWS.
What about the implementation team?
My company works with Splunk directly to help us with the implementation, and our experience with the product has been great.
What was our ROI?
I have not seen an ROI.
What's my experience with pricing, setup cost, and licensing?
The pricing model is great. You can choose between workloads or volume. I am not part of the conversation about pricing in my organization. I just know what I know about the tool from learning about Splunk.
What other advice do I have?
I rate the tool a ten out of ten.
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Three people were involved in the deployment.
What about the implementation team?
The implementation was completed in-house.
What's my experience with pricing, setup cost, and licensing?
Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors.
While Splunk Enterprise Security carries a higher cost and requires budgeting, cheaper SIEM, and open-source alternatives often have limitations. This makes the decision a matter of weighing the cost against the features most important to each organization's security needs.
What other advice do I have?
I would rate Splunk Enterprise Security nine out of ten.
On paper, Splunk Enterprise Security is the top solution for detecting security threats in any organization, but Splunk Enterprise Security is expensive and most organizations don't have a proper budget to implement a SIEM solution. So they look for a more reasonable cost-effective solution. This is a hurdle for implementing Splunk Enterprise Security. It was originally designed for data science and modified for security. It is a top tool for SIEM and data analytics.
Splunk Enterprise Security stands out for its threat detection capabilities, but its cost can be a barrier for many organizations. Originally designed for data science, it excels in both security and analytics, but its price tag often pushes businesses towards more budget-friendly SIEM solutions.

Provides complete visibility, analyzes malicious activities, and improves detection times
Pros and Cons
- "Splunk Enterprise Security offers valuable features like seamless integration and a SQL-standard Structured Query Language for easy searching."
- "Splunk's implementation process for managing multiple indexes can be complex, especially when dealing with a large number of components."
What is our primary use case?
We use Splunk Enterprise Security to secure our client's network and provide clear visibility.
Our client lacked an SIEM solution to comply with regulations, so we recommended Splunk Enterprise Security, and they agreed to implement it.
How has it helped my organization?
Splunk Enterprise Security provides complete visibility into the environment. We can add any data to the indexer, and it will begin to be displayed. All we need to do is create use cases tailored to the client's needs.
Splunk's threat intelligence management capabilities are strong, thanks to its user-friendly interface and ability to correlate data from various sources. While it competes favorably with other SIEM tools, its effectiveness ultimately depends on how it's configured.
The actionable intelligence from Splunk's threat intelligence management feature helps us understand what's happening in our environment, enabling further investigation.
We updated the IOCs within the MITRE ATT&CK framework indexing for Splunk. This allows us to compare all received alerts against the MITRE ATT&CK categories. By using the MITRE ATT&CK framework, I can identify the potential type of threat, its mitigation strategies, and the overall attack behavior. Furthermore, I can use the framework to investigate the affected hosts, their origin, and the attack vector.
Splunk Enterprise Security does a good job analyzing malicious activities and detecting breaches.
Splunk Enterprise Security has improved our detection time.
Splunk Enterprise Security has improved our clients' security posture by providing them with better visibility into vulnerabilities, along with proper mitigation strategies and clear explanations. The benefits are apparent within the first month.
Splunk Enterprise Security helped us reduce our alert volume. Initially, the high number of alerts was overwhelming because we were in a new environment, but the volume gradually leveled off and decreased by 50 percent.
Splunk Enterprise Security has accelerated our security investigations by 30 percent. It integrates seamlessly with our EDR solution, providing a single pane of glass view for all security logs.
What is most valuable?
Splunk Enterprise Security offers valuable features like seamless integration and a SQL-standard Structured Query Language for easy searching. Additionally, implementing devices is straightforward, similar to a plug-and-play process.
What needs improvement?
Splunk's insider threat detection capabilities have limitations. While it offers customization, pre-configured rules for common threats are scarce. This means we need to create our own rules, which can be effective if we have the expertise and understand our specific needs. However, behavior analytics seem less useful and have room for improvement.
Splunk's implementation process for managing multiple indexes can be complex, especially when dealing with a large number of components.
Splunk could benefit from a feature that allows users to indicate they are working on an alert or incident. This would prevent other users from wasting time investigating the same issue. Ideally, this wouldn't involve a formal assignment, but rather a temporary indication that someone is currently looking into it.
For how long have I used the solution?
I have been using Splunk Enterprise Security for 9 months.
What do I think about the stability of the solution?
Splunk Enterprise Security is reliable and the stability is a ten out of ten.
Splunk Enterprise Security offers good resilience. Even for unsupported tools, simple integrations can be customized. Splunk is constantly improving.
What do I think about the scalability of the solution?
I would rate the scalability of Splunk Enterprise Security ten out of ten.
How are customer service and support?
The technical support team is excellent. They proactively identify and inform clients about any vulnerabilities or security gaps in their environment.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial deployment of Splunk Enterprise Security was fairly straightforward. While the documentation is comprehensive, fully deploying the solution can be time-consuming. The timeframe can vary depending on your environment's complexity. For instance, a company with 1500 to 2000 employees and a large number of systems and servers might require a month for complete deployment.
I collect the client's requirements and then open a support ticket with Splunk. The ticket will address configuration assistance and, if the deployment is in the cloud, will inquire about the client's storage needs. After I submit the ticket, Splunk will communicate directly with the client.
The deployment involves several teams, and I lead the oversight of both the deployment itself and the analytics function, ensuring a seamless process.
What's my experience with pricing, setup cost, and licensing?
While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions. Ultimately, the value it delivers justifies the investment.
Don't simply choose the cheapest SIEM solution. Consider your organization's specific needs and environment. Even if you prioritize affordability right now, I can offer more powerful tools. However, the best solution isn't just about price. It depends entirely on your environment. Therefore, you need to establish a budget based on your specific requirements. Ultimately, the ideal SIEM solution aligns with your organization's needs.
What other advice do I have?
I would rate Splunk Enterprise Security 8 out of 10.
Splunk Enterprise Security requires maintenance for new onboarding, log management, and archiving. A maximum of two people are required for the maintenance.
Splunk Enterprise Security is a robust security solution that's easy to manage after initial configuration.

Helps improve our incident response time, and provides great visibility, but the deployment is complex
Pros and Cons
- "Splunk Enterprise Security's dashboards are a key asset."
- "The presence of multiple layers creates a significant challenge for monitoring across cloud environments."
What is our primary use case?
We use Splunk Enterprise Security for threat detection on our network devices.
How has it helped my organization?
Splunk Enterprise Security excels at threat detection. We've developed multiple correlation searches leveraging security data. These searches identify threats and categorize them by urgency level, enabling our security analysts to prioritize and take swift action.
Splunk Enterprise Security has helped us improve our incident response time. We achieve this by ensuring our queries are completed in near real-time.
Access management focuses on storing and managing access controls, while identity management deals with user identities. For example, if we want to find IP addresses associated with CrowdStrike, we can use access management to look up their IP ranges. Then, we can check if any IPs match by adding them to a specific identity management lookup. Finally, by leveraging the combined identity and access management features of Splunk Enterprise Security, we can create correlations between these entities.
The security dashboard can be customized to display the information we need most quickly. It typically has seven to eight panels, each dedicated to reflecting specific data. While some initial data load time might be present, clicking on a specific panel will display its information as soon as possible. There can be delays in traditional dashboards when searching for specific data. To optimize this, we can create "base searches" within each panel. These predefined searches cover commonly used queries and fields. Alternatively, we can create a "summary index" that holds a longer span of pre-processed data. This summary index allows even large datasets to be displayed quickly when accessed through the dashboard.
Splunk enhances our team collaboration regarding security incidents. When a threat alert is received, we can click on it and choose "investigation in progress" from a dropdown menu. This selection redirects us to a dedicated investigation page for further details. For in-depth analysis, we can drill down into the logs to pinpoint the source of the issue. Additionally, the platform allows us to contact network devices to determine the root cause. Once the issue is resolved, we can close the investigation.
We monitor both AWS and GCP environments using Splunk Enterprise Security.
Splunk provides threat intelligence capabilities that can be valuable. This, combined with the comprehensive set of dashboards available, allows us to effectively monitor for threats. We can also create custom apps within Splunk for threat detection. These apps can include custom dashboards or reports that display specific information. For example, we could create a dashboard that shows the number of users accessing unknown URLs or another that monitors a particular device for suspicious activity. An example of suspicious activity might be a device where the print command is being executed repeatedly but failing each time. This could indicate a malfunction or, potentially, a malicious attempt to exploit the system. Similarly, a sudden spike in activity, such as millions of clicks on a specific device within a short timeframe, could also be a sign of a threat. By monitoring these parameters within Splunk's threat detection features, we can identify and investigate potential security incidents.
Splunk provides valuable visibility across multiple environments. Whether we have an on-premises or cloud architecture, Splunk offers self-monitoring capabilities. Additionally, depending on our environment, we can leverage existing monitoring tools. For on-premises deployments, we can utilize the Martin Console alongside Splunk for comprehensive monitoring. Cloud environments often come with built-in monitoring handled by the cloud provider's support team. In such cases, Splunk can focus on applications and custom log data for deeper insights.
The threat topology provided by Splunk gives us a comprehensive overview of potential threats. By analyzing queries or notable events, we can identify and neutralize these threats.
Splunk does a good job of analyzing malicious activities.
Splunk has improved our organization's decision-making by centralizing all the information in our environment and allowing us to access multiple dashboards and reports in one place.
Splunk has helped us reduce our alert volume. By using Splunk, we can identify the root causes of failures, which in turn leads to a decrease in alerts.
Splunk accelerates our security investigations by enabling us to resolve issues and document them in Standard Operating Procedures or knowledge-base articles. This facilitates a swifter response to similar incidents in the future.
What is most valuable?
Splunk Enterprise Security's dashboards are a key asset. They offer comprehensive visibility across our entire environment, allowing us to diagnose and address security issues directly from the interface.
What needs improvement?
I would like Splunk to offer a quicker and easier way to run queries.
Splunk could improve its cost-efficiency for our organization by offering pre-built architectures tailored to specific environments. This would provide a clearer picture of required licenses and their implementation, ultimately reducing licensing costs.
The presence of multiple layers creates a significant challenge for monitoring across cloud environments.
For how long have I used the solution?
I am currently using Splunk Enterprise Security.
What do I think about the stability of the solution?
Splunk Enterprise Security is a very stable product, but there are occasional bugs that can appear.
What do I think about the scalability of the solution?
We can scale Splunk Enterprise Security up or down depending on our demands.
How are customer service and support?
The Splunk support team is helpful. For complex issues or on-demand requests, we raise cases with them. On-demand requests requiring impactful solutions are paid. However, for UK-based users, standard support is free and usually resolves issues efficiently. In some cases, the support team rushes to provide a solution without even looking at the issue.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial deployment can be complex. It involves creating multi-site clusters for each location and configuring a cluster master for each. This is because the cluster master will replicate data across multiple sites, making the environment more complex.
Four people were required for the deployment.
What other advice do I have?
I would rate Splunk Enterprise Security 6 out of 10 because of the complexities that occur at times.
I highly recommend Splunk Enterprise Security for organizations seeking comprehensive security monitoring. Splunk offers a centralized platform to collect and analyze vast amounts of security data. This empowers us to gain full visibility across our entire IT environment, including applications, user activity, and potential security threats. Splunk provides insightful dashboards, reports, and real-time alerts to help proactively identify and address security issues.
While cost is a consideration, prioritizing features over functionalities for SIEM solutions can be risky. It's best to identify your business needs first and then choose an SIEM that offers the most relevant benefits to address those needs.
Splunk Enterprise Security is deployed across multiple locations and departments within our organization.
Splunk Enterprise Security required maintenance.
