Featured Reviews

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

"The solution is flexible and easy to use."
"This solution has allowed us to correlate logs from multiple sources."
"Regarding the tool's ability to maintain high-security standards, I rate it ten out of ten."
"We have the abilities to monitor each instance which originates on the process along with the performance of each department."
"The integration of third-party technologies with IBM Security QRadar is one of the high points they have; they integrate with almost anybody, anywhere, and there's an integrator tool for almost anything."
"The most valuable features would have to be the products' ability to customize vulnerability management settings."
"There are a lot of great out-of-the-box features included."
"It has a lot of good correlation rules. From a customer's point of view, it is one of the best solutions because you don't need to create correlation rules from scratch. You just review them and customize them as you want."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"The product is scalable."
 

Cons

"The product does not have a team for investigating malware."
"There should be more opportunity for community kind of distribution where, for example, if there was a zero-day threat targeting companies."
"The only challenge is that IBM has been a closed enterprise. It should be more open to integrating with other providers at an enterprise level. We're a bank and the core banking system integration is not way straightforward and there is no integration between IBM and these products. If IBM could open up and provide a way of integrating it seamlessly, without charging more for it, that would make a big difference."
"The released patch quality is poor. IBM should test those patches on their side, not on the client's side."
"IBM QRadar Advisor with Watson could be more user-friendly. You need some skills and understanding of what you're looking at, especially if you're going to draw down specific information."
"QRadar log integration of various applications can be a tough job at times. There may be occasions when you will not find any QRadar guide on adding logs of a particular application. Even if you come across one, adding a log process is not an easy one."
"QRadar needs to be improved on the storage side, particularly when the disc exceeded the maximum threshold."
"The weak signal detection with QRadar needs improvement. You can detect what you know, but what is unknown to the rule engine can't be detected."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"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 support could be better."
"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."
 

Pricing and Cost Advice

"IBM Security QRadar is a very expensive tool."
"It's too expensive. The licensing is also a little bit difficult to understand because you have to license it per event and per number of flows."
"The price of this solution is a little high."
"It's not expensive for the resources that it gives you."
"Licensing is very expensive, IBM QRadar is a very expensive solution. If you want to minimize costs then IBM QRadar is not for you."
"A good approach would be to begin with an On Cloud subscription, then later on do a more exact sizing."
"It is costlier as compared to the other alternatives available in the market."
"The pricing is good."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"For a single instance, the price is around $4,000."
"We found the pricing to be quite affordable."
