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.
Stephen-Armstrong - PeerSpot reviewer
The SIEM provides a user-friendly UI experience
When events come into the system, the dashboard categorizes them by the highest risk score, not when they appear on the system. When you've got multiple ongoing incidents you can only see the highest risk score at the top of the list rather than the most recent detection. Exabeam's reporting dashboard could have included a filtering option to filter by the most recent detection.

Pros

"The initial setup is straightforward."
"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."
"AlienVault OSSIM's GUI is very user-friendly."
"You can customize the dashboards as well as the reporting."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

Cons

"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"It's so hard to configure and explore something new on it."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"Sometimes technical issues take very long to get resolved."
"The user interface could be improved."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"AlienVault OSSIM gives unwanted notifications."
"They should provide detailed information about detecting phishing emails."
"I believe if it were more flexible it would be a better product."
"Adding to the number of certifications that they have, for example, ISO 27001, would be helpful."
"The solution's reporting and dashboarding could be improved."
"Exabeam needs to improve its documentation and provide more customization for dashboards and case management."

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"AlienVault OSSIM is expensive compared to its competitors."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"OSSIM is free."
"The solution is open source, so it's free to use."
"There is an annual license required to use Exabeam Fusion SIEM. The price of the solution should be reduced."
