Executive SummaryUpdated on Nov 30, 2025

AlienVault OSSIM and Wazuh compete in the open-source security information and event management (SIEM) space. Wazuh seems to have the upper hand due to its impressive integration capabilities and adaptability for complex environments.

Features: AlienVault OSSIM offers unified security management with features like threat detection, incident response, and compliance management in one platform. Wazuh provides real-time threat detection, intrusion detection, and flexible deployment options, allowing for more customization. Wazuh's ability to integrate smoothly with other security tools and cloud environments enhances its adaptability across various IT infrastructures.

Room for Improvement: AlienVault OSSIM could improve scalability and responsiveness of its customer support. Enhancements in integration options could boost its adaptability. Documentation could be more comprehensive. Wazuh could simplify its initial setup and offer better in-house support options. Expanding its compliance standards to new regions could widen its appeal. More native features could reduce customization needs.

Wazuh offers an involved setup due to its customizability while providing strong community support, extensive documentation, and active forums for troubleshooting and guidance.

Pricing and ROI: AlienVault OSSIM is cost-effective initially for small organizations because of its free options but might incur higher scaling expenses.

Enables cost-effective security management for small businesses

Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

Has faced limitations in AI capabilities and pricing flexibility

Pricing-wise, Wazuh stands out, along with deployment flexibility and its documentation which is extremely good in comparison to Forti. The community support is also incredible. They have helped quite a bit because previously, we had a separate tool and management dashboard to do our compliance. With Wazuh, we receive that information without having to do anything extra. We just set up the SIEM and all of that information was automatically populated. The dashboards are very easy to understand and very quick with no lag or delay. I have experienced delays on Forti's dashboards, but not with Wazuh. Wazuh is quite good. In comparison to Forti, they are quite similar. They are very good at detection.

Quotes from Members

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

Pros

"The product is majorly used for threat detection of the agents on servers and endpoints."

"With AlienVault you get everything in one box."

"You can customize the dashboards as well as the reporting."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."

"The initial setup was straightforward. I didn't have any problems."

More AlienVault OSSIM pros

"Some of the strengths of Wazuh that stand out for us include its scalability when deployed on Azure, its open-source nature, which allows for customization based on our needs, and its compatibility with various security solutions like threat intelligence platforms."

"Wazuh's best features are syscheck, its ability to immediately resolve vulnerabilities, and that it's open source."

"Wazuh has very flexible and robust features."

"I find the PCI DSS feature the most valuable, along with the feature that monitors the compliance of Windows and the CIS benchmarks on other devices like Unix or Linux systems."

"Overall, I rate Wazuh a nine out of ten."

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

"Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs."

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

More Wazuh pros

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"I don't like to work on OSSIM because it is unpredictable."

"AlienVault OSSIM’s configuration and integration could be a little easier."

"GUI could be improved."

"The correlation engine needs to be improved."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."

"AlienVault OSSIM gives unwanted notifications."

More AlienVault OSSIM cons

"I want more support for regional compliance standards to serve my ANZ region customers better."

"Since it's an open-source tool, scalability is the main issue."

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

"Wazuh doesn't have native support for some enterprise solutions."

"Alerts should be specific rather than repeatedly triggered by integrating multiple factors. This issue needs improvement to create a more efficient alert system."

"An issue I noticed is with tag values in certain rules not functioning properly."

"The biggest part that's missing is threat intelligence. It isn't inbuilt, and if a sudden incident occurs, we don't get that feedback inside the SIEM tool. That's a big gap, I see. It would be better if we could get the threat intelligence feeds integrated with the SIEM tools. That would help us push value solutions to the clients in a big way."

"There's not much I like about Wazuh. Other products I've used were a lot more functional and user friendly. They came with reports and use cases out of the box. We need to configure Wazuh's alerts and monitoring capabilities manually. It'd be nice if we could select from templates and presets for use cases already built and coded."

More Wazuh cons

Pricing and Cost Advice

"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."

"OSSIM is free."

"The tool's licensing costs are yearly."

"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."

"AlienVault OSSIM is an open-source solution."

"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."

"AlienVault OSSIM is free."

"AlienVault OSSIM is expensive compared to its competitors."

More AlienVault OSSIM pricing and cost advice

"Wazuh is open-source, so I think it's an option for a small organization that cannot go for enterprise-grade solutions like Splunk."

"The solution's cost is above the average."

"The product price is neither too high nor too low."

"The solution's pricing is very competitive."

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

"It is a free-of-cost solution."

"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."

"They have a good pricing strategy for market expansion."
