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.

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

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

Pros

"Asset discovery is good."

"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 solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"The product is easy to use."

"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."

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

More AlienVault OSSIM pros

"Exabeam Fusion SIEM has a good performance and more advantages than traditional solutions."

"The advanced analytics has a really great overview of user behavior."

"The platform is not extremely expensive compared to its direct competitors; I would rate its pricing around six out of ten."

"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 solution's initial setup process is easy."

"Exabeam has improved our organization by speeding up the investigation process."

"The most valuable feature of Exabeam is the timeline creation based on log sources, which helps in security investigations."

"The UI was very clean."

More Exabeam pros

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

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

"The user interface could be improved."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."

"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."

"Sometimes technical issues take very long to get resolved."

"AlienVault OSSIM gives unwanted notifications."

More AlienVault OSSIM cons

"Adding to the number of certifications that they have, for example, ISO 27001, would be helpful."

"Exabeam needs to improve its documentation and provide more customization for dashboards and case management."

"Exabeam needs to improve its adaptive nature towards rules and its capability to understand the entire client environment faster."

"The solution's reporting and dashboarding could be improved."

"They need to focus on more of the MITRE ATT&CK Framework and coverage. They claim they cover about 70 to 80%. I'm not sure if it's really quite that much, however."

"Updating the new release of Exabeam Fusion SIEM takes time and slows our performance."

"We still have questions surrounding hardware deployment."

"The organzation is rigid and not flexible in the way they operate"

More Exabeam cons

Pricing and Cost Advice

"The solution is open source, so it's free to use."

"AlienVault OSSIM is expensive compared to its competitors."

"AlienVault OSSIM is free."

"OSSIM is free."

"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."

"We are using the community version, which can be used for free."

"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 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."

More AlienVault OSSIM pricing and cost advice

"Exabeam is not a cheap solution."

"The solution is expensive."

"There is an annual license required to use Exabeam Fusion SIEM. The price of the solution should be reduced."

"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."

"The platform is not extremely expensive compared to its direct competitors; I would rate its pricing around six out of ten."
