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 product is easy to use."
"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."
"Better than other SIEM solutions because almost everything can be integrated."
"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."
"You can customize the dashboards as well as the reporting."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"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," and the solution works well and allows me to have visibility into anomalous events."
"The correlation rules and the user platform are most 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."
"ClearSkies is the best for software as a service and small organizations with up to 500 employees."
 

Cons

"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"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."
"The price of this solution is very high and it could be cheaper."
"I would advise others to not implement it for any enterprise-level organization."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"They can add behavior analytics and AI or machine learning technology."
"The main issue for improvement is the platform's slowness in presenting information. Retrieving information can take a little time when clicking on something."
"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."
 

Pricing and Cost Advice

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"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."
"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."
"The solution is open source, so it's free to use."
"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."
"We are using the community version, which can be used for free."
"The tool's licensing costs are yearly."
"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."
