Featured Reviews

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

"The threat protection network is the most valuable feature, because when you get an offense, you can actually trace it back to where it originated from, how it originated, and why."
"The query search and log fetching are really helpful in IBM Security QRadar when compared to other tools."
"It is a scalable solution."
"IBM Security QRadar has impacted my organization positively by helping me with many things, including catching attacks and moving quickly to reduce damage or risk from attacks."
"Vulnerability detection is the most valuable feature. It's the tool that finds the threats."
"The ability to add extensions is the most valuable feature. For example, extensions that provide valuable test ports."
"This solution has allowed us to correlate logs from multiple sources."
"This console gives you the entire view, which makes life easier and allows you to take precautionary measures."
"The product is scalable."
"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."
 

Cons

"IBM needs to invest more into the collaboration with other vendors."
"Technical support really needs to be improved. Right now, they aren't where they need to be at all."
"The features that could be improved include the licensing model and the dashboards and all those presentations. Overall, the user experience part can be improved."
"There could be better integration with the solution."
"The solution is expensive compared to other products."
"When it comes to what could be better, it is always what others are trying to do and what is the roadmap. It can have more integration. It should have more flexible RESTful APIs for integration with applications. These are the things that are always in demand for any of the SIEM solutions, not only for QRadar. Integration is ever-evolving. Nowadays, different versions of mobile handsets are there and data is getting scattered. Users are using their personal handsets to keep the data of the organization. So, it should have a more flexible integration, irrespective of the flavor of the firmware and iOS or Android version. It should have an API that can seamlessly get integrated. It should also provide more flexible control and a more advanced or analytical view to see what exactly is happening across the globe or network. From wherever a user is connecting and accessing the enterprise data, it should give real-time visibility and predictive visibility about what exactly is happening. These things are already there, but there should be more advanced control in terms of managing the security."
"Solution has too many menus that require going to two or three sub-monitors to enter the QRadar."
"I would like to see some artificial intelligence and alternative solutions."
"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."
"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."
 

Pricing and Cost Advice

"IBM's Qradar is not for small companie. Unfortunately, it would be 'overkill' to place it plainly. The pricing would be too much."
"The solution's pricing is based on the EPS model."
"It could be cheaper, but the value itself is far more important for us than the price. Typically, our clients have yearly subscriptions."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate IBM Security QRadar's pricing a five out of ten."
"The license is not subscription-based."
"The cost of this product is expensive."
"We use QRadar as a managed service and we pay licensing fees to the partner."
"It is cheaper than ArcSight."
"We found the pricing to be quite affordable."
"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."
