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

"This solution provides me with various alarms, and I have found security issues with some of my other products."
"IBM Security QRadar's AI and machine learning capabilities for threat detection and response are exceptional, and Q Site is used to create panels and visualizations of software development processes."
"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."
"This console gives you the entire view, which makes life easier and allows you to take precautionary measures."
"We run 65 servers globally with just two people: an engineering person and me."
"The integration of third-party technologies with IBM Security QRadar is one of the high points they have; they integrate with almost anybody, anywhere, and there's an integrator tool for almost anything."
"This solution has excellent security analytics."
"The scalability is good."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"The solution lacks some maturity."
"There is a shortage of skilled individuals with knowledge about the solution. There is training required."
"The Indian tech support is not helpful."
"We sometimes experience downtime, but it depends on the version. There is some variability."
"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 biggest problem was built on top of the QRadar in the executive operations center network. The integration was not using the network security specialist properly, and all the incidents were inferior with QRadar. Its compatibility is not really good."
"It would be better if it were more stable and more secure. The price for maintenance could be better. It's too high. In the next release, I think they should focus on the price and the operation."
"Improving the integration with IBM Server for MetaMask for correlation rules would be beneficial. Currently, I use Sentinel in Azure, and I would prefer creating one rule to roll it out to both Sentinel and QRadar. However, this is not possible because QRadar lacks this capability."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"We use QRadar as a managed service and we pay licensing fees to the partner."
"It's free of charge."
"Licensing is very expensive, IBM QRadar is a very expensive solution. If you want to minimize costs then IBM QRadar is not for you."
"The tool's price is high."
"The pricing is always fine."
"Our licensing costs for this solution is on a yearly basis."
"There are additional costs, such as the cost associated with the different hardware required for implementation and deployment. Along with the add-on apps, these are all additional costs, and they require licensing as well."
"The solution's pricing is based on the EPS model."
"Security Onion is an open-source solution."
"It is an open-source solution."
"Security Onion is a free solution."
