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

"Stability-wise, I rate the solution a ten out of ten."
"We run 65 servers globally with just two people: an engineering person and me."
"One of the most valuable features of this solution is it has very good data correlation."
"This solution provides me with various alarms, and I have found security issues with some of my other products."
"It comes with many rules disabled. You can tune them and modify them according to your enterprise needs and avoid false positives."
"The solution is flexible and easy to use."
"In terms of the most valuable features, the log collections and log processing mechanisms are good. They have good dashboards."
"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."
"A great feature of the solution involves its internal portal."
"The product is scalable."
"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

"Solution has too many menus that require going to two or three sub-monitors to enter the QRadar."
"For future updates, I'd like to see more advanced threat intelligence features integrated with AI. This would help with analyzing traffic patterns and improving protection. QRadar currently doesn't integrate with AI for threat analysis. However, AI could enhance its capabilities by learning traffic patterns and automatically blocking or quarantining suspicious traffic. This would be especially useful when administrators are not actively monitoring. AI could help by analyzing incoming and outgoing traffic and adjusting policies accordingly."
"Its architecture is very complicated."
"There should be more focus on small and medium businesses, especially given the number of FinTechs and entrepreneurs in Mexico that require easier solutions with less budget."
"There are reports that I would like to generate that are either not included, or I cannot find."
"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."
"The usability of interfaces could be improved."
"It is not app based."
"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 support could be better."
"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."
 

Pricing and Cost Advice

"QRadar is quite expensive. It wouldn't be worth it for a small business..."
"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 cheaper than ArcSight."
"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 licensing is also overly complex, as there is a need to buy the work load performance monitoring separately."
"There is a license to use this solution, which is paid annually. However, there are subscription options available."
"As for licensing costs, I haven't seen the exact figures, but it is considered somewhat costly. On a scale from one to ten, where one is very expensive and ten is very cheap, I would rate it a six—it’s costly but worth the money."
"The solution is costly and the price differs depending on the vendor you use."
"For a single instance, the price is around $4,000."
"We found the pricing to be quite affordable."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
