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.

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

"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 most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"With AlienVault you get everything in one box."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"I recommend it due to the experience of the people running it."
"The initial setup was straightforward. I didn't have any problems."
"The setup is not difficult. It was easy."
"Exabeam has improved our organization by speeding up the investigation process."
"The UI was very clean."
"The Exabeam SIEM has a user friendly UI interface."
"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 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."
"The most valuable feature of Exabeam Fusion SIEM is the easy-to-use user interface."
 

Cons

"The user interface needs to be friendlier across the board."
"Sometimes technical issues take very long to get resolved."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"I don't like to work on OSSIM because it is unpredictable."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"They can add more compliance templates."
"They should provide detailed information about detecting phishing emails."
"The organzation is rigid and not flexible in the way they operate"
"Exabeam needs to improve its documentation and provide more customization for dashboards and case management."
"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."
"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 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."
"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."
"The customer service and support are not satisfactory."
 

Pricing and Cost Advice

"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."
"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 tool's licensing costs are yearly."
"AlienVault OSSIM is free."
"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."
"AlienVault OSSIM is an open-source solution."
"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."
"We are using the community version, which can be used for free."
"Exabeam is not a cheap solution."
"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."
