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.
Zuhair Hasan - PeerSpot reviewer
Manager, Information Technology Security at Nesma
Has good integration capability and provides information and events but improvement is needed in information retrieval speed
The best features are the comprehensive event collection and analysis. Once set up properly, we receive all events and information. The team analyzes our data and presents incidents to us. We can communicate with their team to escalate and resolve incidents. It has a feature we use to search for information about our environment and past incidents. This is very valuable. The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of this solution are the data correlation and vulnerability assessment."
"The solution is free to use."
"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."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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 feature is the logging capability."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"AlienVault OSSIM's GUI is very user-friendly."
"The correlation rules and the user platform are most valuable."
"ClearSkies is the best for software as a service and small organizations with up to 500 employees."
"The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets."
 

Cons

"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"The correlation engine needs to be improved."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"We need more dashboards and we need more customization for dashboards."
"They can add more compliance templates."
"The documentation could be improved."
"They can add behavior analytics and AI or machine learning technology."
"They can add behavior analytics and AI or machine learning technology. They also improve their correlation engine. In addition to collecting logs from devices, they can collect the traffic and then correlate these logs and the traffic information."
"The main issue for improvement is the platform's slowness in presenting information. Retrieving information can take a little time when clicking on something."
 

Pricing and Cost Advice

"The tool's licensing costs are yearly."
"AlienVault OSSIM is free."
"The solution is open source, so it's free to use."
"We are using the community version, which can be used for 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."
"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 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."
"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."
"They have changed the pricing policy. Its price is competitive. Its price is less than half of the price of QRadar, LogRhythm, and Splunk."
"Regarding pricing, I'd say it's in the middle range. Pricing is very good compared to others."
