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 detection is the most valuable feature. It's the tool that finds the threats."

"The threat hunting capabilities in general are great."

"There are new things that are coming up in QRadar, such as AI to IBM Watson, which is going to create a huge impact in these types of solutions."

"The security has improved my organization."

"Most of our clients have seen a return on investment because compared to other solutions it does not require a busload of people to operate it and it is reasonably priced."

"The visibility it gives you into your infrastructure has been great."

"QRadar shows very effective correlations. If you combine all the logins plus user behavior and the current intelligence, it gives a very good correlation for business. I think it reduces the false positives in user activity monitoring because there is a lot of social information to correlate with other data."

"Customer service is very good and technical support is excellent."

More IBM Security QRadar pros

"The product is scalable."

"A great feature of the solution involves its internal portal."

"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."

"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."

Cons

"I don't give it a 10 because it is something we have to request. I would love it if UBA was included out of the box like Microsoft."

"I don't look at only the features and benefits; I also look at the price. It is a bit expensive when compared with other solutions. It is expensive for specific deployment topologies, and the decision-makers go for alternatives like ArcSight. It should also have more AI features or capabilities for better threat intelligence. The more it uses machine learning, the better would be the dashboard, analytics, and other things."

"Technical support could be improved by a bit."

"Technical support really needs to be improved. Right now, they aren't where they need to be at all."

"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."

"I would like to see more APIs available in order to provide tighter integrations between other IBM products and third-party solutions."

"Our consultants are taking too much time understanding the product's technical aspects."

"I gave IBM Security QRadar a score of six or seven out of ten because it has a very basic interface; the dashboards require extension management for better usability."

More IBM Security QRadar cons

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

"The configurations during initial setup could be improved."

"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 pricing is higher but cheaper than others and there are no additional costs."

"The price of this solution is a little bit expensive, so if it were cheaper then it would help."

"The cost of this product is expensive."

"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."

"The license is not subscription-based."

"There is a license to use this solution, which is paid annually. However, there are subscription options available."

"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."

More IBM Security QRadar pricing and cost advice

"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."

"We found the pricing to be quite affordable."
