Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Hrishiraj Bhattacharjee - PeerSpot reviewer
Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"On the back-end, Watson helps me figure out an exact problem, sometimes giving me the result."
"Blocks of predefined conditions can be used to configure detection rules without having to write complicated script."
"There is a single dashboard that gives us a complete overview of what is happening around the globe."
"It can analyze event logs, event security, and give a good consult."
"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."
"QRadar UBA's most valuable feature is the risk rating of users depending on their behavior."
"It is suitable for large companies with critical infrastructure. For our clients, robustness, availability at a high level, and the level of references and experiences connected to the solution are important."
"It's a state-of-the-art product for security information and event management (SIEM)."
"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

"I think that the search speed of this solution could be improved."
"We need more features in order to create rules to detect or to meet some requirements for other areas, for example, catching the event from other authentication tools."
"QRadar's performance has room for improvement because it cannot handle the volume. I need massive amounts of logs from various devices in our existing network architecture. IBM needs to improve QRadar's capacity to handle more logs."
"I have noticed the interface has room for improvement."
"The quoting and the dashboard session could be improved. It should be more user-friendly."
"Do your research before implementing it, because it is tough to implement."
"There was some complexity in the initial setup due to bandwidth issues."
"The initial setup was complex, and it took six months."
"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

"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."
"A good approach would be to begin with an On Cloud subscription, then later on do a more exact sizing."
"It's very expensive but it fits our budget."
"It is overly expensive and overly complex in terms of licensing. They have many different appliances, which makes it extremely difficult to choose the technology. It is very difficult to choose the technology or QRadar components that you should be deploying. They have improved some of it in the last few years. They have made it slightly easy with the fact that you can now buy virtual versions of all the appliances, which is good, but it is still very fragmented. For instance, on some of the smaller appliances, there is no upgrade path. So, if you exceed the capacity of the appliance, you have to buy a bigger appliance, which is not helpful because it is quite a major cost. If you want to add more disks to the system, they'll say that you can't."
"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."
"Pricing (based on EPS) will be more accurate."
"This price is a little high, so it's an expensive product."
"The price of this solution is a little bit expensive, so if it were cheaper then it would help."
"It’s a single license platform."
