Executive SummaryUpdated on Aug 25, 2025

AlienVault OSSIM and Wazuh are competing network monitoring solutions. Wazuh seems to have the upper hand due to its comprehensive features and higher long-term return on investment.

Features: AlienVault OSSIM offers extensive integration capabilities, built-in threat intelligence, and a solid security information and event management solution. Wazuh, however, provides flexible log data analysis, numerous customization options, and integrative security modules, making it adaptable for different infrastructures.

Room for Improvement: AlienVault OSSIM could enhance its alert responsiveness and improve accuracy in log collection without relying on external agents. It might also benefit from better user behavior analytics. Wazuh could work on improving compliance for specific regional standards and refining its user interface for easier use. It could also extend its support to a broader range of compliance standards.

In contrast, Wazuh excels with a community-driven support system and a flexible open-source model, offering customizable deployment strategies that provide more control over security adaptations.

An open-source solution that provide good detection and more visibility

The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Innovative platform enables proactive threat hunting and endpoint monitoring

I have not seen Wazuh moving in the direction of AI-driven threat detection projects myself, but since the market is moving that way, I wouldn't be surprised if they implemented it soon. My plans to increase the usage of Wazuh or switch to another tool depend on what my boss decides. We don't refer to any community support specifically, as we rely on other platforms such as GitHub or Discord, depending on the application. I recommend that as more companies come on board with Wazuh, it will motivate those who contribute to it, but I am also cautious that as it gains attention, a large company might buy it and change its course of business. Overall, I rate Wazuh a nine out of ten.

Pros

"I recommend it due to the experience of the people running it."

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

"AlienVault OSSIM's GUI is very user-friendly."

"The most valuable feature is the logging capability."

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."

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

More Wazuh pros

Cons

"AlienVault OSSIM gives unwanted notifications."

"They can add more compliance templates."

"We need more dashboards and we need more customization for dashboards."

"The solution needs more integration with cyber intelligence systems."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"AlienVault OSSIM is costly."

"The correlation engine needs to be improved."

"The incidence reporting could be better."

More AlienVault OSSIM cons

"I think that the next release should be more suitable for large enterprises, because currently they are not because large companies do not rely on open source solutions."

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

"A lack of certain features creates limitations."

"The deployment is a bit complex."

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

"They could include flexibility and customization capabilities by modifying for customers based on partner agreements."

"Wazuh could improve the detection, it is not detecting all of the attacks. Additionally, it is lacking features compared to other solutions."

"So far, the recent updates have addressed most challenges we previously faced."

More Wazuh cons

Pricing and Cost Advice

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"AlienVault 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."

"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."

"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."

"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 open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."

More AlienVault OSSIM pricing and cost advice

"Wazuh is free and open source."

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

"Wazuh is open-source, therefore it is free. You can purchase support for $1,000 a year."

"There is not a license required for Wazuh."

"The product is cheaper compared to other tools."

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

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

"The current pricing is open source."
