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

"The product is majorly used for threat detection of the agents on servers and endpoints."

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

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

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

More AlienVault OSSIM pros

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

"Exabeam is very easy to use, with a straightforward platform and workflow, unlike other tools that require more expertise."

"The most valuable feature of Exabeam is the timeline creation based on log sources, which helps in security investigations."

"The way it can connect with AWS is very useful, and the integrations are pretty good."

"I have customers that like the EUBA functionality of it. The solution has the ability to build a session, basically. It pulls a lot of information together, for example, everything a user does in a specific timeframe. It's quite helpful."

"Exabeam has improved our organization by speeding up the investigation process."

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

More Exabeam pros

Cons

"The solution needs more integration with cyber intelligence systems."

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"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."

"They can add more compliance templates."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"GUI could be improved."

"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."

"The documentation could be improved."

More AlienVault OSSIM cons

"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."

"We still have questions surrounding hardware deployment."

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

"Updating the new release of Exabeam Fusion SIEM takes time and slows our performance."

"One area for the solution's improvement is integration capabilities, particularly out-of-the-box integration which sometimes requires additional professional services."

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

"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 organzation is rigid and not flexible in the way they operate"

More Exabeam cons

Pricing and Cost Advice

"The tool's licensing costs are yearly."

"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."

"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."

"AlienVault OSSIM is free."

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

"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."

More AlienVault OSSIM pricing and cost advice

"Exabeam Fusion SIEM's pricing is reasonable."

"Exabeam is not a cheap solution."

"The solution is expensive."

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

"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."
