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

"AlienVault OSSIM's GUI is very user-friendly."

"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

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

"The product is easy to use."

"Asset discovery is good."

"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 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."

More AlienVault OSSIM pros

"The setup is not difficult. It was easy."

"The UI was very clean."

"It's a very user-friendly product and it's a very comprehensive technology."

"The solution's automation capabilities are great."

"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."

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

"Timeline based analysis; good platform support"

More Exabeam pros

Cons

"It's so hard to configure and explore something new on it."

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

"Lacking in depth of reporting."

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

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

"The documentation could be improved."

"The incidence reporting could be better."

"They can add more compliance templates."

More AlienVault OSSIM cons

"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 initial setup of Exabeam Fusion SIEM is complex because it needs to integrate with the SIEM solution, but after this is complete it is straightforward."

"Exabeam's reporting dashboard could have included a filtering option to filter by the most recent detection."

"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."

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

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

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

More Exabeam cons

Pricing and Cost Advice

"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."

"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 price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."

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

"AlienVault OSSIM is an open-source solution."

"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."

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

More AlienVault OSSIM pricing and cost advice

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

"They have a great model for pricing that can be based either on user count or gigabits per day."

"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."

"The solution is expensive."

"Exabeam is not a cheap solution."
