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.
Jörg Kippe - PeerSpot reviewer
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"It'll get you from point A to B."
"The tool helps with infrastructure, application, and network monitoring."
"We have worked with other solutions, such as LogRhythm and Splunk. Compared to others, IBM QRadar has the best price-performance ratio so that you are able to reserve minimum costs. It starts settling in fast and gets the first results very quickly. It is also very scalable."
"One very useful feature is the plug-in offering that allows you to integrate it with other solutions, such as integrating it with plug-ins like Scout, Carbon Black, and the rest."
"The features that I have found most valuable in QRadar are its data enrichment, use case creations, and adding references - those kinds of features are very good. Also QRadar's event filtration and device integration are perfect."
"It helps us discover any threats with their alerts and tracking."
"Most of our clients are interested in automation. The automation part is good because they are able to detect threats and vulnerabilities in real time. It's very fast."
"This console gives you the entire view, which makes life easier and allows you to take precautionary measures."
"We use Security Onion for internal vulnerability assessment."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
 

Cons

"The user interface is a bit difficult to get used to."
"Some of the cloud apps need improvement."
"IBM is going through some problems with its resources currently making its support response time slow."
"The whole process for support is something that needs to be improved."
"AI is superb but need improvements."
"The implementation and configuration are not easy."
"I'd like them to improve the offense. When QRadar detects something, it creates what it calls offenses. So, it has a rudimentary ticketing system inside of it. This is the same interface that was there when I started using it 12 years ago. It just has not been improved. They do allow integration with IBM Resilient, but IBM Resilient is grotesquely expensive. The most effective integration that IBM offers today is with IBM Resilient, which is an instant response platform. It is a very good platform, but it is very expensive. They really should do something with the offense handling because it is very difficult to scale, and it has limitations. The maximum number of offenses that it can carry is 16K. After 16K, you have to flush your offenses out. So, it is all or nothing. You lose all your offenses up until that point in time, and you don't have any history within the offense list of older events. If you're dealing with multiple customers, this becomes problematic. That's why you need to use another product to do the actual ticketing. If you wanted the ticket existence, you would normally interface with ServiceNow, SolarWinds, or some other product like that."
"I would like to see some artificial intelligence and alternative solutions."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"An X-Force feed is free with QRadar."
"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."
"It is expensive. It is not a product that I can provide for SMBs. It is a program that I can only provide for really large enterprises."
"It's very expensive but it fits our budget."
"The price of this solution is a little high."
"IBM QRadar is a little bit expensive compared to other products."
"Pricing is good."
"The pricing is always fine."
"It is an open-source solution."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
