An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Enables automated threat intelligence sorting and enhances proactive threat hunting capabilities
You have to have at least a threat intelligence background or a SOC analyst background to use it, as that's the information you'll dig around with in there. If you don't have that kind of knowledge, it probably can be a little hard to use, but they do provide training. They offer training not only for how to use the platform but also some basic threat intelligence training to explain what these things are and what these terms mean. My company is a customer of Anomali. I would recommend it to other people. I would advise making sure you don't pick it without testing other products and have your use cases well thought out and documented before testing, so you know it will solve the problems you're trying to address. Keep an open mind with it and realize that whatever you can dream of, you can probably do with the platform. Overall, I would rate Anomali an eight out of ten.

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 threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"The product is easy to use."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The solution is free to use."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"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 paid version of the solution has reporting and better scalability options."
"We now have a very robust collection of threat intelligence based on the capabilities that Anomali provides."
"I have found Cyber threat intelligence (CTI) very useful and concise. The solution is easy to use."
"The most valuable aspect of Anomali is the threat modeling capability."
"The feature I have found most valuable is credential monitoring. This feature is easy and quick."
 

Cons

"The documentation could be improved."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"I don't like to work on OSSIM because it is unpredictable."
"It's so hard to configure and explore something new on it."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"The solution needs more integration with cyber intelligence systems."
"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."
"Less code in integration would be nice when building blocks."
"A lot of tools can give you many features, such as CTI intelligence and a tax service reduction. However, many people are combining different tools together to have more capabilities. It is up to the consumer whether they want to have multiple tools or have one tool that serves the purpose. Anomali Enterprise could improve by combining all the other tools' features into one solution."
"Support in the past has been top-notch, but recent trends indicate that it has taken a back seat, as we often don't get answers for days."
"An area for improvement is the intelligence sharing within the Anomali community. The tagging system can be inconsistent, as any company can use any tags for their reporting."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"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."
"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 tool's licensing costs are yearly."
"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."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is free."
"When comparing the price of Anomali Enterprise to other solutions it is in the medium to high range. However, I am satisfied with the price."
