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.

Quotes from Members

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

Pros

"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."
"With AlienVault you get everything in one box."
"The solution is free to use."
"The most valuable feature is the logging capability."
"I recommend it due to the experience of the people running it."
"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 most valuable features of this solution are the data correlation and vulnerability assessment."
"The security level that they are maintaining with the pre-authentication keys is very good."
 

Cons

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The documentation could be improved."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"It's so hard to configure and explore something new on it."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"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 solution could improve by providing better documentation for beginners to learn, such as videos or other tutorials."
 

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."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The solution is open source, so it's free to use."
"The solution is not expensive for the data security measure you receive, it is reasonable."

Questions from the Community

What is your experience regarding pricing and costs for AlienVault OSSIM?
It depends. I would need to review their cost models, but generally, they are on a scaled basis based on throughput usage. Because it's a software as a service solution for their core product for U...
What needs improvement with AlienVault OSSIM?
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 implement...
