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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"Due to the skills shortage, we are able to use it from the standpoint of bringing in a lower level employee or a person who may not have security knowledge."
"think QRadar is great overall. We’ve had a positive experience with it and recommend it for deployment. However, there are areas for improvement. The technical support is good, and the documentation is valuable, but it could be enhanced, especially regarding integration with other systems. In terms of support and updates, QRadar’s capabilities are crucial for maintaining high security standards. Network and software administrators can monitor all traffic effectively, which reassures clients and drives further adoption."
"It protect us from multiple authentication values, unauthorized access and antivirus threats."
"It provides many options for searching. I can see devices from different vendors, like Cisco, in one interface, which is good for me."
"The most valuable feature is user behavior analytics (UBA)."
"It's user-friendly when compared to other products."
"The most valuable feature is the QRadar Vulnerability Manager which provides vulnerability scans. In addition, I like the way QRadar generates alerts."
"Providing real-time visibility for threat detection and prioritization - QRadar SIEM provides contextual and actionable surveillance across the entire IT infrastructure."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"The technical support can be improved a little bit, and the price could be cheaper."
"I have also been working with other SIEM solutions, and I have observed that they have extensive Linux-based and Unix-based integrations. They have been able to support some of the Linux-based agents, which is useful to investigate and process the information on the Linux and Unix side."
"Ideally we would like a mobile version so that any alert that comes in will notify us in a mobile app, or by using SMS integration."
"For the common needs of clients to fulfill requirements, a real integration with Blueworks Live (BPA modeling tool also from IBM) and a more suitable BPM on cloud solution for midsize customers."
"We sometimes get an error about the hard drive. Approximately once in two months, we can't find the logs, and they go missing, which is a terrible issue. We are getting support for this issue from our support company."
"Needs better visualization options beyond the time series charts and a few other options that they have."
"Integration could be better. They should make it easy to integrate with other solutions."
"The solution lacks some maturity."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"IBM QRadar is a little bit expensive compared to other products."
"It is a perpetual license that we have for the event collector. The licensing is done based on the number of events and flows that you receive on this particular device. These are perpetual licenses, which means once you purchase them, they don't expire, which means that the support to IBM is definitely renewed after every one year. We have an enterprise agreement with IBM, which puts the cost in a totally different category as compared to someone who is not an IBM partner and is approaching IBM for this solution. We were able to get massive discounts. To give you an idea, we recently purchased 30,000 event licenses, and it costs around $480,000. It is definitely not a cheap product. We have licenses for about 270,000 events per second and 3 million flows per second. All the appliances and their events and flows are basically clubbed together and charged or rather calculated through a single source. The console receives all the details from all the event processes that we have globally. So, the license that we have is a single license for 270,000 events per second and 3 million flows per second, but that can be managed centrally. I was only part of the secondary purchase, which was 30,000 events per second for about $480,000. You can calculate how much we paid for 270,000 events. Reducing its price would be a compromise. We have already used a lower-priced product in the form of NNT, but we had to get rid of it because it was not doing the job that we actually wanted to do. You get what you pay for."
"IBM has subscriptions plans that run for one year."
"I feel that the price is reasonable but compared to other products that are on the market, such as an offering by Microsoft, it is more expensive."
"On a scale of one to ten, I rate the price a one, where one is an extremely expensive product, and ten is a cheap product."
"It could be cheaper, but the value itself is far more important for us than the price. Typically, our clients have yearly subscriptions."
"The pricing is higher but cheaper than others and there are no additional costs."
"It's free of charge."
"It’s a single license platform."
