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.

Solution Architect at CTC

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

"The most valuable feature is the logging capability."

"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

"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."

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."

"Better than other SIEM solutions because almost everything can be integrated."

"I recommend it due to the experience of the people running it."

"With AlienVault you get everything in one box."

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

More AlienVault OSSIM pros

"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 setup is not difficult. It was easy."

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

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

"The most valuable feature of Exabeam Fusion SIEM is the easy-to-use user interface."

"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."

More Exabeam pros

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

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

"The correlation engine needs to be improved."

"The user interface could 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."

"AlienVault OSSIM’s configuration and integration could be a little easier."

"The price of this solution is very high and it could be cheaper."

More AlienVault OSSIM cons

"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."

"Exabeam's integration capabilities are not good, as Exabeam has a very limited number of integrations and no out-of-box integration, which is an area where Exabeam should improve."

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

"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."

"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."

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

"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."

More Exabeam cons

Pricing and Cost Advice

"AlienVault OSSIM is free."

"AlienVault OSSIM is expensive compared to its competitors."

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

"The tool's licensing costs are yearly."

"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."

"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."

"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 OSSIM is an open-source solution."

More AlienVault OSSIM pricing and cost advice

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

"Exabeam is not a cheap solution."

"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."

"The solution is expensive."
