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

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

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

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

"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."

"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 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."

"The product is easy to use."

More AlienVault OSSIM pros

"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."

"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 solution's automation capabilities are great."

"The Exabeam SIEM has a user friendly UI interface."

"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."

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

"The UI was very clean."

More Exabeam pros

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"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."

"I don't like to work on OSSIM because it is unpredictable."

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

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

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

"They can add more compliance templates."

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

More AlienVault OSSIM cons

"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."

"We still have questions surrounding hardware deployment."

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

"We use the on-prem Exabeam product and face limitations using the web UI and administration of custom models and rules."

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

"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."

"Exabeam needs to improve its adaptive nature towards rules and its capability to understand the entire client environment faster."

"I believe if it were more flexible it would be a better product."

More Exabeam cons

Pricing and Cost Advice

"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."

"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."

"OSSIM is free."

"AlienVault OSSIM is an open-source solution."

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

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

"The tool's licensing costs are yearly."

More AlienVault OSSIM pricing and cost advice

"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 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."

"The solution is expensive."
