Enables cost-effective security management for small businesses
Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

Improved threat detection has provided clear user risk insights and streamlined incident response
Exabeam's UEBA is the most valuable feature that I have found so far. Exabeam's UEBA displays the type of description that it could show in a console regarding one particular user, the rating that it shows, and how vulnerable the user is, which is very good. Exabeam's automation for incident response is very good. The machine learning capabilities of Exabeam are also good.

Quotes from Members

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

Pros

"With AlienVault you get everything in one box."
"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 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 solution is free to use."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"The initial setup was straightforward. I didn't have any problems."
"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 UI was very clean."
"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."
"Exabeam has improved our organization by speeding up the investigation process."
"Timeline based analysis; good platform support"
"The setup is not difficult. It was easy."
"The way it can connect with AWS is very useful, and the integrations are pretty good."
"It is user-friendly and quite simple to use."
"It's a very user-friendly product and it's a very comprehensive technology."
 

Cons

"The incidence reporting could be better."
"The price of this solution is very high and it could be cheaper."
"The correlation engine needs to 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."
"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 initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"AlienVault OSSIM gives unwanted notifications."
"The user interface could be improved."
"We still have questions surrounding hardware deployment."
"We use the on-prem Exabeam product and face limitations using the web UI and administration of custom models and rules."
"One area for the solution's improvement is integration capabilities, particularly out-of-the-box integration which sometimes requires additional professional services."
"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."
"Updating the new release of Exabeam Fusion SIEM takes time and slows our performance."
"I believe if it were more flexible it would be a better product."
"The only problem is that the UI is not very impressive."
"Exabeam's reporting dashboard could have included a filtering option to filter by the most recent detection."

"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."
