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

"I have used IBM QRadar User Behavior Analytics in a Cloud Pak on Amazon, and there it runs on top of it and is easy to assess. Additionally, I have installed processes and characters."

"I find that the dashboards are the most helpful to get an overview of traffic flow and issues."

"It is a very good SIEM."

"This product helps us to find security incidents before they become a problem to the business."

"The most valuable feature for us is probably the intelligence we get out of the product."

"IBM QRadar User Behavior Analytics has easy architecture, has a good portfolio and integration."

"With QRadar we managed to focus on the more critical incidents that we have experienced and as a result we have managed to decrease the most critical incidents and most critical attacks, and now we are focusing on the ones that are not too heavy or too critical so at the moment we are more secure than before."

"What's most valuable in IBM QRadar User Behavior Analytics is its higher availability than other tools."

More IBM Security QRadar pros

"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."

"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."

"The initial setup of Nagios Log Server was easy and straightforward."

Cons

"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 product can be a bit complex."

"The price is very high."

"GUI needs to be improved."

"If you are searching for three to four months back it takes and there is a time delay. If I compare it to Splunk, it is a little bit delayed."

"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."

"To be very frank, it's not that much help as of now. We are not getting that many insights from UVA, which we wanted, actually."

"The API integration for AD is a problem when it comes to vulnerability management. If you want to incorporate multiple factor authentication it becomes a problem with the AD. It doesn't integrate well. That needs to be improved."

More IBM Security QRadar cons

"The configurations during initial setup could be improved."

"The support could be better. They only offer email support."

"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."

"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."

Pricing and Cost Advice

"The maintenance costs are high."

"QRadar's price is reasonable compared to LogRhythm."

"The tool's price is high."

"This price is a little high, so it's an expensive product."

"I think that the price is fair, but we can always say that the price could be cheaper."

"Only enterprise businesses can afford the tool."

"Pricing (based on EPS) will be more accurate."

"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."

More IBM Security QRadar pricing and cost advice

"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."
