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.

"The product is easy to use."

"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."

"The paid version of the solution has reporting and better scalability options."

More AlienVault OSSIM pros

"Exabeam Fusion SIEM has a good performance and more advantages than traditional solutions."

"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."

"It is user-friendly and quite simple to use."

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

"The UI was very clean."

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

More Exabeam pros

Cons

"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."

"GUI could be improved."

"They can add more compliance templates."

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

"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."

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

"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."

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."

"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."

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

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

"Exabeam lacks customizable dashboards, which might be a limitation if visualization is a key requirement."

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

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

"The customer service and support are not satisfactory."

More Exabeam cons

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."

"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."

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

"OSSIM is free."

"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."

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

"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."

"AlienVault OSSIM is expensive compared to its competitors."

More AlienVault OSSIM pricing and cost advice

"Exabeam Fusion SIEM's pricing is reasonable."

"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."

"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."

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