Featured Reviews

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.
Mahmoud Younes - PeerSpot reviewer
Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.

Quotes from Members

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

Pros

"With AlienVault you get everything in one box."
"The initial setup is straightforward."
"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.""
"Asset discovery is good."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The solution is free to use."
"The dashboard is easy to use and easy to understand what's going on and what the alerts mean."
"It is really helpful to us from the compliance point of view."
"The most valuable feature currently is security behaviors and the pdf files."
"We find predictive analysis capabilities valuable."
"It has improved comprehensive visibility for what is going on in the perimeters, and on the inside, as well."
"The most valuable features of IBM Security QRadar are flexibility, IBM support, and scalability."
"The feature that I find the most useful is that IBM QRadar User Behavior Analytics is free of charge. It's a fully free product that can be installed on top of IBM QRadar SIEM."
"IBM QRadar has improved my organization by introducing many functions. It collects logs from all of our systems in the organization and has functioned very well. It alerts and correlates the aggregate events or offenses we receive through all the applications we use."
 

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"The incidence reporting could be better."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"GUI could be improved."
"The correlation engine needs to be improved."
"We need more dashboards and we need more customization for dashboards."
"The solution is not scalable."
"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 is difficult to understand in the beginning and has complex management configurations that can be improved."
"Technical support could be improved by a bit."
"A lot of information that we receive for the devices is IP-based, but it would help if we could have a default dashboard in which we can add more details about the assets for which we are receiving the information. For example, if it is a Windows or Linux device, we only get the IP for that particular device. We don't really get the name and other details of that particular device. For that, you have to drill down into your own asset management system. It would be good to have a place where we can probably add this information so that we don't have to look into other tools."
"The modularity could be improved."
"The architecture could be improved. I got stuck for a long time trying to understand the architecture, as it is quite challenging."
"IBM Security QRadar lacks automated response. With this feature, there's no need to visit VirusTotal or other sites for IP reputation. There should be a small plug-in where users can click to retrieve details about the reputation and organization of public IP."
"From a functionality point of view there are issues sometimes."
"It doesn't have a SOAR system by default. You need to purchase it additionally, which is the main problem with QRadar."
 

Pricing and Cost Advice

"OSSIM is free."
"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."
"We are using the community version, which can be used for 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."
"AlienVault OSSIM is 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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault OSSIM is expensive compared to its competitors."
"IBM's Qradar is not for small companie. Unfortunately, it would be 'overkill' to place it plainly. The pricing would be too much."
"Pricing and licensing are competitive. Their new licensing options allow logs to bypass the correlation engine for a flat rate, which is also appealing for log data that is compliance-driven for a small amount of money."
"The pricing is good."
"It could be cheaper, but the value itself is far more important for us than the price. Typically, our clients have yearly subscriptions."
"There are additional costs, such as the cost associated with the different hardware required for implementation and deployment. Along with the add-on apps, these are all additional costs, and they require licensing as well."
"I would like for them to lower the price."
"The tool's price is high."
"The solution is priced fairly, there is a license for the solution, and we pay annually."

What SOC product do you recommend?
