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.

Pros

"Exabeam has improved our organization by speeding up the investigation process."
"The solution's automation capabilities are great."
"It's a very user-friendly product and it's a very comprehensive technology."
"The most valuable feature of Exabeam Fusion SIEM is the easy-to-use user interface."

"Timeline based analysis; good platform support"
"The solution's initial setup process is easy."
"The platform is not extremely expensive compared to its direct competitors; I would rate its pricing around six out of ten."
 

Cons

"AlienVault OSSIM gives unwanted notifications."
"They can add more compliance templates."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"I don't like to work on OSSIM because it is unpredictable."
"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 solution is not scalable."
"The correlation engine needs to be improved."
"The solution needs more integration with cyber intelligence systems."
"We use the on-prem Exabeam product and face limitations using the web UI and administration of custom models and rules."
"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."
"Adding to the number of certifications that they have, for example, ISO 27001, would be helpful."
"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 organzation is rigid and not flexible in the way they operate"
"The solution's reporting and dashboarding could be improved."
"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."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"AlienVault OSSIM is expensive compared to its competitors."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"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."
"OSSIM is free."
"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."
"They have a great model for pricing that can be based either on user count or gigabits per day."
"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."
"The solution is expensive."
"The platform is not extremely expensive compared to its direct competitors; I would rate its pricing around six out of ten."
"Exabeam is not a cheap solution."
