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

"The solution is flexible and easy to use."
"Improved our organization's TCO."
"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."
"IBM Qradar's ability to simplify the number of events, not only on a technical level but by making that information easy to pan through the orchestration deduplication. It is very impressive given that we have hundreds of devices that send event logs through."
"We have the abilities to monitor each instance which originates on the process along with the performance of each department."
"What I like about IBM QRadar User Behavior Analytics is that it uses machine learning algorithms to generate risk scoring for the user activity. I also like that it syncs with our Active Directory users, so it really has full coverage for all users in our environment."
"The tool's most valuable feature is real-time detection."
"The solution can scale."
"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 don't give it a 10 because it is something we have to request. I would love it if UBA was included out of the box like Microsoft."
"The user interface needs improvement."
"It's resource-intensive."
"The quoting and the dashboard session could be improved. It should be more user-friendly."
"The solution is highly used here in Pakistan and in many sectors, they could improve it by having more SIEM connectors."
"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."
"The features that could be improved include the licensing model and the dashboards and all those presentations. Overall, the user experience part can be improved."
"The dashboard and reports are not user-friendly or efficient so are of little help with threat hunting activity."
"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 of one to ten, I rate the price a one, where one is an extremely expensive product, and ten is a cheap product."
"It is very expensive."
"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."
"It's too expensive. The licensing is also a little bit difficult to understand because you have to license it per event and per number of flows."
"There is a license required for this solution and it is an annual payment. I have found all solutions in the category to be expensive, including Splunk."
"found other solutions, with more features at the same cost or less. You don’t have to leave the Gartner Magic Quadrant to beat their price."
"It's free of charge."
"There is a license required for this solution."
"It’s a single license platform."
