Featured Reviews

HarshBhardiya - PeerSpot reviewer
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.

Quotes from Members

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"You can customize the dashboards as well as the reporting."
"The most valuable feature is the logging capability."
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"The product is easy to use."
"Exabeam includes machine learning features and out-of-the-box rules that we rely on."
"The setup is not difficult. It was easy."
"The most valuable feature of Exabeam is the timeline creation based on log sources, which helps in security investigations."
"The user interface and the timelines they use are the most valuable features. The price model is very simple so that one can understand it easily and there are no surprises within it."
"The most valuable feature of Exabeam Fusion SIEM is the easy-to-use user interface."
"The solution's automation capabilities are great."
"The UI was very clean."
"The way it can connect with AWS is very useful, and the integrations are pretty good."
 

Cons

"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."
"I don't like to work on OSSIM because it is unpredictable."
"Lacking in depth of reporting."
"Sometimes technical issues take very long to get resolved."
"GUI could be improved."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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."
"The solution needs more integration with cyber intelligence systems."
"Exabeam should be a bit faster, especially in loading and vulnerability scanning."
"I believe if it were more flexible it would be a better product."
"Updating the new release of Exabeam Fusion SIEM takes time and slows our performance."
"The customer service and support are not satisfactory."
"The organzation is rigid and not flexible in the way they operate"
"Exabeam lacks customizable dashboards, which might be a limitation if visualization is a key requirement."
"One area that needs improvement is interacting with Exabeam's API. There was a headache regarding the API; the documentation wasn't clear, and the syntax wasn't very precise."
"Exabeam needs to improve its adaptive nature towards rules and its capability to understand the entire client environment faster."
 

Pricing and Cost Advice

"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."

"The solution is open source, so it's free to use."
"AlienVault OSSIM is expensive compared to its competitors."
"OSSIM is free."
"The tool's licensing costs are yearly."
"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."
"Exabeam is not a cheap solution."
"The solution is expensive."
"The platform is not extremely expensive compared to its direct competitors; I would rate its pricing around six out of ten."
"Exabeam Fusion SIEM's pricing is reasonable."
"They have a great model for pricing that can be based either on user count or gigabits per day."
"There is an annual license required to use Exabeam Fusion SIEM. The price of the solution should be reduced."
