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.
Syarul Idzuddin Adzmi - PeerSpot reviewer
A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution 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

"IBM Qradar's ability to simplify the number of events, not only on a technical level but by making that information easy to pan through the orchestration deduplication. It is very impressive given that we have hundreds of devices that send event logs through."
"What we like about QRadar and the models that IBM has, is it can go from a small-to-medium enterprise to a larger organization, and it gives you the same value."
"think QRadar is great overall. We’ve had a positive experience with it and recommend it for deployment. However, there are areas for improvement. The technical support is good, and the documentation is valuable, but it could be enhanced, especially regarding integration with other systems. In terms of support and updates, QRadar’s capabilities are crucial for maintaining high security standards. Network and software administrators can monitor all traffic effectively, which reassures clients and drives further adoption."
"It's a state-of-the-art product for security information and event management (SIEM)."
"Most valuable features include the granularity of information."
"The most valuable features are the versatility of this solution and the variety of things you can do with it."
"QRadar has somewhat of a new structure recently from last gen. They have moved from the standard UI based infrastructure."
"It's hard for me to pinpoint any one feature that's most valuable because it is all about consuming logs and analyzing them. We started using QRadar UBA because we needed something that could analyze Linux authentication information. Other products take care of the Windows platform."
"The product is scalable."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
 

Cons

"I need a solution which will send alerts in the event of any behavior."
"IBM QRadar User Behavior Analytics is good, but I think the functionality should be much more integrated. You should have easy access to the artifacts if you are doing a particular investigation. It's good, but other team solutions like LogRhythm are actually merging the functionality. So, I think that is something IBM can work on."
"It needs more resilience and functionality."
"I would like to see some artificial intelligence and alternative solutions."
"The user interface and configurability of IBM QRadar User Behavior Analytics can be improved. It has a lot of pre-configured settings and not many things can be changed. It also needs more integrations. Currently, User Behavior Analytics is integrated only with IBM QRadar. It could have deeper integrations. It can also have more complicated scoring models. Currently, it has a very simple linear scoring model for users."
"I would like for Yara to be supported by all components."
"There is a lot of manual configuration required in order for the product to run smoothly, and I think that it could be made more automatic."
"The playbook guide which specifies the rules for security use cases needs to be provided to support in case the organization needs help."
"The support could be better."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"There are different types of subscriptions available. We were on an annual subscription, but our customers typically choose the two years subscription option."
"The licensing is also overly complex, as there is a need to buy the work load performance monitoring separately."
"The price of this solution is a little bit expensive, so if it were cheaper then it would help."
"The product is expensive. We have purchased the perpetual license, but we pay for the support."
"The cost of this product is expensive."
"found other solutions, with more features at the same cost or less. You don’t have to leave the Gartner Magic Quadrant to beat their price."
"The solution's pricing is based on the EPS model."
"IBM Security QRadar is a very expensive tool."
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"We found the pricing to be quite affordable."
