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

"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""

"The paid version of the solution has reporting and better scalability options."

"The product is easy to use."

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

"With AlienVault you get everything in one box."

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

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

More AlienVault OSSIM pros

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

"The ThreatHunter in Advanced Analytics is the most valuable. It helps analyze compromised assets and provides analysis for any entity within my client's environment."

"Timeline based analysis; good platform support"

"The Exabeam SIEM has a user friendly UI interface."

"Exabeam includes machine learning features and out-of-the-box rules that we rely on."

"Exabeam is very easy to use, with a straightforward platform and workflow, unlike other tools that require more expertise."

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

"I have customers that like the EUBA functionality of it. The solution has the ability to build a session, basically. It pulls a lot of information together, for example, everything a user does in a specific timeframe. It's quite helpful."

More Exabeam pros

Cons

"The solution is not scalable."

"The user interface needs to be friendlier across the board."

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

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"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."

"AlienVault OSSIM is costly."

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

More AlienVault OSSIM cons

"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."

"They should provide detailed information about detecting phishing emails."

"The only problem is that the UI is not very impressive."

"We use the on-prem Exabeam product and face limitations using the web UI and administration of custom models and rules."

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

"I believe if it were more flexible it would be a better product."

"We had a large volume right from the beginning and they weren't quite prepared for that. That's something that they should think about when it comes to customers that have a large volume to start off with."

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

More Exabeam cons

Pricing and Cost Advice

"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."

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

"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."

"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."

"AlienVault OSSIM is free."

"AlienVault OSSIM is an open-source solution."

More AlienVault OSSIM pricing and cost advice

"Exabeam is not a cheap solution."

"The solution is expensive."

"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."

"Exabeam Fusion SIEM's pricing is reasonable."

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