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

"You can customize the dashboards as well as the reporting."

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

"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 AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"The solution is free to use."

"The initial setup is straightforward."

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

More AlienVault OSSIM pros

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

"The user interface and the timelines they use are the most valuable features. The price model is very simple so that one can understand it easily and there are no surprises within it."

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

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

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

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

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

"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

"Sometimes technical issues take very long to get resolved."

"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."

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

"It's so hard to configure and explore something new on it."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"We need more dashboards and we need more customization for dashboards."

"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."

More AlienVault OSSIM cons

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

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

"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."

"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."

"Exabeam should be a bit faster, especially in loading and vulnerability scanning."

"Exabeam's reporting dashboard could have included a filtering option to filter by the most recent detection."

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

More Exabeam cons

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

"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."

"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 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 tool's licensing costs are yearly."

More AlienVault OSSIM pricing and cost advice

"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."

"The solution is expensive."

"Exabeam is not a cheap solution."

"Exabeam Fusion SIEM's pricing is reasonable."
