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.

Provides good threat hunting by finding infected ports, but its initial setup is difficult
The most valuable feature of Security Onion for security monitoring is its ability to find infected ports. I have used the Squert tool within Security Onion the most for threat hunting The initial setup of the solution is a little bit difficult. I have been using Security Onion for one year.…

Quotes from Members

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

Pros

"I am fond of IBM Security QRadar because it is very user-friendly."
"IBM QRadar User Behavior Analytics's most important feature is its ease of use."
"The flexibility is good in terms of pulling log files."
"The solution can scale."
"The most valuable aspect of the solution is the integration capabilities on offer."
"The visibility it gives you into your infrastructure has been great."
"QRadar has somewhat of a new structure recently from last gen. They have moved from the standard UI based infrastructure."
"I think it's a very stable product that provides much more visibility than the other product."
"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

"We have had problems with networking."
"The interface is very old. IBM should remake it into a more modern interface."
"Solution has too many menus that require going to two or three sub-monitors to enter the QRadar."
"The solution lacks vendor support."
"Sometimes it takes time to load queries, but other than that, it performs excellently."
"Whenever we are upgrading or installing any type of patch, at that time we have some delays."
"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."
"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."
"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

"The product is expensive. We have purchased the perpetual license, but we pay for the support."
"The solution is costly and the price differs depending on the vendor you use."
"The tool's price is high."
"It's free of charge."
"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 very expensive."
"They can give us some scalability and flexibility on pricing. If its pricing can be reduced, it would help a lot of customers in bringing in a new SIEM environment and grow business in the market. If I start a license today and take around 10,000 EPS, and after a month, there is an increase in the number of clients on my platform, I can increase the number of licenses. I can add 5,000 EPS on a yearly basis."
"It is expensive. It is not a product that I can provide for SMBs. It is a program that I can only provide for really large enterprises."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
