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 mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is user behavior analytics (UBA)."
"This is a distributed application, meaning that a customer can stack small and then scale it so that they can expand pretty effectively. You can use, basically, the same product in an SMB or a large enterprise."
"Almost every feature is useful."
"We were using a different solution, and we moved to QRadar; it has some more benefits than our previous solution, and we have totally transferred to QRadar now."
"I equate QRadar to a robust solution."
"It is a scalable solution."
"The most valuable feature is the DSM Editor."
"This solution provides me with various alarms, and I have found security issues with some of my other products."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"IBM QRadar User Behavior Analytics could improve machine learning use cases because they are limited and most of the use cases are rule-based. They should develop more use cases, such as in Securonix or Exabeam because they will detect a threat. Using machine learning is mainly on the correlation rules, but if you think about Exabeam or Securonix, they detect using machine learning or machine learning-based algorithms."
"QRadar needs to be improved on the storage side, particularly when the disc exceeded the maximum threshold."
"IBM QRadar could improve the plugins and threat detection."
"We were very disappointed."
"They have to build more quantitative monitoring, profiling, and make it more predictive."
"I would like to see some artificial intelligence and alternative solutions."
"Its architecture is very complicated."
"However, too many issues existed with the product and too many more appeared as they tried to fix different issues."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"We use QRadar as a managed service and we pay licensing fees to the partner."
"The licensing is also overly complex, as there is a need to buy the work load performance monitoring separately."
"IBM QRadar is a little bit expensive compared to other products."
"IBM Security QRadar is a very expensive tool."
"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."
"When it comes to the initial pricing there can be a huge discount from there side and also I think they are open to competing with other products."
"The maintenance costs are high."
"The tool is priced in a competitive manner. The tool's price is dependent on the installation and the product size, but it is competitive in the marketplace."
"It is an open-source solution."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
