HarshBhardiya - PeerSpot reviewer
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

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"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."
"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 case management, ease of configuration, and investigation."
"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.""
"I recommend it due to the experience of the people running it."
More AlienVault OSSIM pros
"Log-monitoring and alerting enable us to know when things happen that we need to know about."
"AlienVault provides a checklist answer when using SIEM."
"The USM is a work horse, no matter what devices or the number of logs we throw at it, the system processes them in real time, correlates the events, and alerts on only events that need human review."
"It provides a single pane of glass view, coupled with a whole security ecosystem. The ability to manage everything from a central point, including vulnerability assessments, asset management - including the services provided by the various hosts, NIDS, HIDS, etc. - provides a very efficient way of dealing with things."
"AlienVault has an advanced component within one package. With this, we can cover more area with one solution."
"In terms of monitoring, my best feature would be the monitoring of components across the network. It monitors the respective nodes and any new node that comes onto the network and provides reports. The reporting dashboards are really helpful for management in terms of making decisions around patch management."
"It has streamlined log aggregation and analysis to meet organizational and regulatory needs."
"This is a USM, so being able to get all the features under one roof makes it a good product with good new features."
More USM Anywhere pros
 

Cons

"The incidence reporting could be better."
"The correlation engine needs to be improved."
"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."
"AlienVault OSSIM is costly."
"AlienVault OSSIM gives unwanted notifications."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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
"I think plugin management should be self-service on AlienVault USM. The other product is self-service but on the USM side. You have to submit a ticket then AT&T creates and updates the plugins."
"The solution already has quite good tools, however, they need better integration tools for linking with Office 365, Google Suite, and so on."
"The one thing I continue to dislike about the USM is the limitation on reports."
"It would be nice to see some machine learning and monitoring of the configuration in network devices."
"Their threat intelligence platform needs to be broadened. They should integrate it with more threat intelligence platforms. For the threat feed that they get from open intelligence, I would like them to add a few premium threat intelligence platforms. They can provide a bundle in which AlienVault has the threat intelligence background of other premium products."
"they seem to have bugs from time to time that go unfixed for a while and that is frustrating. I'm not saying the product needs to be bug-free, but they need to be responsive to bugs."
"This solution could be easier to use."
"The GUI needs to improve because it's not user-friendly."
More USM Anywhere cons
 

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."
"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."
"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 an open-source solution."
"AlienVault OSSIM is free."
"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."
More AlienVault OSSIM pricing and cost advice
"They are a little more expensive than Microsoft."
"Use the AlienVault team. They are helpful and the documentation that they provide is second to none."
"​The price point is good.​"
"It's very reasonably priced. It was one of the lowest among the ones I looked at. Licensing is pretty flexible. They can do a two-year or a three-year, even a one-year, perhaps."
"Use an MSSP instead. It is much cheaper."
"The pricing is a good value. The key thing is that for the new product, the licensing of it, is subscription-based and it's based on data. Clients need to be really careful when thinking about that, because odds are they're going to need to put a lot more data into it than what they initially estimate, which is going to drive their subscription costs up."
"Do the one month trial and try to work out the kinks during it, as it has free support and service hours."
"The price of this solution is reasonable, which is one of the reasons why we selected it over other solutions."

Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.
