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

"It helps us discover any threats with their alerts and tracking."

"Integration is very easy and the reporting is good."

"IBM Security QRadar has significantly improved our incident response procedures."

"The most valuable feature is the searching capability and real-time operational use."

"I equate QRadar to a robust solution."

"Scalability is good because it is a cloud-based offering and a managed services offering solution, and the scalability is left for IBM to manage, so it's not a headache for us to manage."

"The most valuable features are all the implementations, the plug-ins, and the User Behavior Analytics (UBA)."

"We get events and make the correlation, or rules. In IBM, we can implement our customer's rules. We can have very clear status threats and severity of antigens."

More IBM Security QRadar pros

"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."

"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."

"The product is scalable."

Cons

"Reporting should be very good, and a proper integration with cloud, not only the IBM cloud, but with other clouds also."

"SOAR is what is expected the most from QRadar. They have something called SOAR Resilient, and it would be great if that gets induced in SIEM. IBM QRadar (as well as McAfee ESM) should have analytics platform integration. Currently, SIEMs don't have full-fledged integration with analytics where we are able to dump our data in SIEM, and the same data can be called from different analytics applications. We should be able to bring this data to a platform like Hadoop for big data and run the analytics there. Currently, people are seeing the past data and taking some actions in the present, but when it comes to analytics, there should be futuristic data where you can predict something out of your present and past data. Apart from that, I would like to see a full-fledged ITSM tool in QRadar. It sometimes has some technical issues that need to be checked. It requires a dedicated QRadar engineer to completely manage it. It has different module sets, such as event collector and event processor, and some technical glitches come in between. It takes the log but doesn't exactly process it in the way we want."

"There are reports that I would like to generate that are either not included, or I cannot find."

"Search capability and indexing still lag behind competitors. We also need to see improved rule based access controls and rule/event tuning."

"There needs to be better integration with other applications."

"They should provide more integration with more devices."

"The solution is difficult to understand in the beginning and has complex management configurations that can be improved."

"There are several vulnerabilities that IBM is working with us on."

More IBM Security QRadar cons

"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."

"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."

Pricing and Cost Advice

"It is costlier as compared to the other alternatives available in the market."

"It's not expensive for the resources that it gives you."

"Its price is good in terms of efficiency and the number of people required for implementing various things. You might pay more in terms of money, but you might save on the number of people. For example, if you are using Kibana, you have to pay more for people or experts, which is not the case with IBM QRadar."

"It's free of charge."

"A good approach would be to begin with an On Cloud subscription, then later on do a more exact sizing."

"You have a one-time payment, and you also can purchase it for one year as a subscription. We have it on-premise, and we have a permanent license for it. We have to pay for the support on a yearly basis. If you compare its cost with Sentinel for one year, QRadar would seem more expensive, but if you compare its cost over five or ten years, Azure Sentinel will be more expensive than QRadar. If you compare its cost with Sentinel for one year, QRadar would seem more expensive, but if you compare its cost over five or 10 years, Azure Sentinel can be more expensive than QRadar."

"The maintenance costs are high."

"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."

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."

"For a single instance, the price is around $4,000."

"We found the pricing to be quite affordable."
