Featured Reviews

HarshBhardiya - PeerSpot reviewer

Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.

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

"Vulnerability data, network data and the like, are part of correlation and detection."
"IBM has everything you need in a cybersecurity solution. If you want to build a cybersecurity operation center version then I think QRadar is a perfect solution."
"Overall a great solution."
"This solution provides me with various alarms, and I have found security issues with some of my other products."
"Improved our organization's TCO."
"A valuable feature is the detection capability, and I like that the solution can use data other than log data which means that things like vulnerability data, network data and the like, are part of the correlation and detection."
"This solution provides me with various alarms, and I have found security issues with some of my other products."
"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 product is scalable."
"A great feature of the solution involves its internal portal."
"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."
"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."
"My company is a featured partner of Nagios XI, so I'm implementing Nagios XI in different companies and supporting the product, and I'd recommend the solution because it offers a lot of benefits and has a good dashboard, it's pretty easy to get up and running, and the pricing is good."
 

Cons

"The price of this solution is a little bit expensive, so if it were cheaper then it would help."
"IBM needs to invest more into the collaboration with other vendors."
"I would like for them to develop a detection management solution. It does not have a detecting management solution in it, you have to buy it as it is, on top of the extended solution."
"The solution's technical support works, but sometimes, it can take quite a long time to get a solution from technical support."
"I would like to see a better GUI."
"The IBM support can be better."
"However, when it comes to IBM, they consider each module as a separate license with a separate cost."
"The setup is very complex; it's not like somebody can walk in and build it."
"The support could be better. They only offer email support."
"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."
"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 configurations during initial setup could be improved."
 

Pricing and Cost Advice

"There is a license required for this solution and it is an annual payment. I have found all solutions in the category to be expensive, including Splunk."
"I would like for them to lower the price."
"Only enterprise businesses can afford the tool."
"The price of this solution is a little bit expensive, so if it were cheaper then it would help."
"The pricing is higher but cheaper than others and there are no additional costs."
"We use QRadar as a managed service and we pay licensing fees to the partner."
"An X-Force feed is free with QRadar."
"Customers have to purchase a license based on the number of users, devices, and applications they want to protect. It allows you to take a license on a subscription basis for three years or five years."
"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."
"For a single instance, the price is around $4,000."
