Executive SummaryUpdated on Jan 5, 2025

Splunk Enterprise Security and Wazuh are key competitors in the security information and event management (SIEM) arena. Splunk appears to have the upper hand with its advanced data processing and robust enterprise capabilities, making it suitable for complex environments.

Features: Splunk Enterprise Security is known for its real-time data collection, powerful search capabilities, and operational intelligence which supports rapid issue diagnosis across a wide range of data sources. Users find its analytics and visualization tools particularly valuable. Wazuh, on the other hand, offers effective log monitoring, intrusion detection, and vulnerability assessments, focusing on compliance and being a cost-effective, open-source option.

Room for Improvement: Splunk can improve its operational workflows, visualization, and user access control while reducing technical complexity and enhancing integration with external ticketing systems. Wazuh could improve its threat detection capabilities and scalability to better handle enterprise-level environments, as well as integrate better threat intelligence for real-time monitoring and automation.

Has many predefined correlation rules and is brilliant for investigation and log analysis

It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Evaluating robust file monitoring with insights for community support improvements

Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs. These aspects are vital as they provide alerts for changes and facilitate the monitoring of compliance. The platform is also relatively easy to set up and operate. Reports are straightforward to extract and prove useful for compliance requirements.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We have a more secure, robust environment, which keeps the harmful software out of the zone required."

"We can automatically suspend or terminate suspicious sessions."

"Overall, Splunk is among the top three SIEM tools due to its capabilities and agility in bridging business analytics with security needs."

"We can ingest and correlate data from virtually any type of system."

"From the class that I took this week, being able to create notable events from whatever you find in the data set is pretty useful."

"Splunk simplifies real-time problem identification and resolution by seamlessly integrating existing customer and vendor systems."

"it can explain to management about what kind of traffic is visiting the network. It can also explain other traffic coming in and out, along with protecting against malware."

"The most valuable features of Splunk Enterprise Security are the enterprise search bar and the dashboards."

More Splunk Enterprise Security pros

"Good for monitoring, active response, and for vulnerabilities."

"Regarding Wazuh, I find the SCA (Security Configuration Assessment) features most valuable. It's crucial for asset management and inventory, allowing us to monitorendpoints and servers' changes easily. This is particularly important for my customers, who aren't heavily focused on incident response but rely on asset management and inventories. Wazuh's compliance management features are very supportive, especially in regions like the Americas and Europe. However, it's less effective in the ANZ (Australia and New Zealand) region since Wazuh doesn't cater to the specific compliance standards there, such as those required in Australia. I appreciate that Wazuh fully complies with PCI DSS and GDPR standards, allowing us to generate necessary reports."

"If they support a solution, it is easy to do an integration."

"It's very easy to integrate Wazuh with other environments, cloud applications, and on-prem applications. So, the advantage is that it's easy to implement and integrate with other solutions."

"The configuration assessment and Pile integrity monitoring features are decent."

"It offers built-in modules for file integrity and vulnerability management."

"I like that the solution is on top of the Kubernetes stack."

"Wazuh automatically scans the host for CIS benchmarks for the latest updates and vulnerabilities and gives a host score. It provides a percentage of perceived risk due to of non patches or any missing patches on that work."

More Wazuh pros

Cons

"Cybersecurity and infrastructure monitoring have room for improvement."

"We find that the maintenance process could be a lot better."

"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."

"Its pricing is extremely high. There are other tools out in the market that are competitive. They do not necessarily have all the functionality, but they are competitive. The professional services we have used have been high as well in comparison to the market."

"Most of my interaction is with the user community, which is how Splunk wants it. When I need help, that community is very hit or miss."

"AngularJS/ReactJS inclusion could be made easier in GUI."

"The use cases provided by Splunk are a good starting point, but could cover many additional topics to ensure that a smaller or less experienced shop might maximize the value of an ES deployment."

"An area of improvement would be the licensing of the solution. They need a free license, which would allow faster lead times."

More Splunk Enterprise Security cons

"Wazuh has a drawback with regard to Unix systems. The solution does not allow us to do real-time monitoring for Unix systems. If usage increases, it would be a heavy fall on the other SIEM solutions or event monitoring solutions."

"A lack of certain features creates limitations."

"The tool doesn't detect anomalies or new environments."

"The support channel is not optimal, and extensive research is required on our part to implement Wazuh effectively."

"Adding the flexibility to integrate various plug-ins or modules into its core system would enhance functionality."

"The deployment is a bit complex."

"The computing resources are consuming and do not make sense."

"They need to go towards integrating with more cloud applications and not just OS like Windows and Linux."

More Wazuh cons

Pricing and Cost Advice

"Setup cost is cheap: It is free, it is user-friendly, and it is fast."

"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."

"The pricing modules could be improved."

"The price is comparable."

"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."

"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."

"I think the price could be improved."

"Our customers often complain that the price of Splunk is too high."

More Splunk Enterprise Security pricing and cost advice

"Wazuh is free and open source."

"The product is cheaper compared to other tools."

"Wazuh is an open-source tool, which means it is freely available for use."

"My client uses the open-source version of Wazuh."

"Wazuh is not an expensive solution."

"Wazuh is a good tool, but the open-source version has scalability limitations."

"The current pricing is open source."

"It is an open-source product."
