Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.
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

"Search capabilities are sufficient for most tasks."
"We are using the platform version, which I like."
"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."
"It is the core of our entire SOX."
"I think it's a very stable product that provides much more visibility than the other product."
"A nice benefit is when we go to the process of selecting our youth cases, they go by building blocks. QRadar links it to building blocks."
"I think QRadar is stable and currently satisfies my needs."
"It has improved my efficiency."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement."
"The only problem is that if you have too many events that occur, then the storage capacity becomes a problem. We would need to increase the storage capacity."
"QRadar log integration of various applications can be a tough job at times. There may be occasions when you will not find any QRadar guide on adding logs of a particular application. Even if you come across one, adding a log process is not an easy one."
"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."
"They should provide more manual examples online so that I can learn it myself."
"The product does not have a team for investigating malware."
"The architecture could be improved. I got stuck for a long time trying to understand the architecture, as it is quite challenging."
"I would also like to see more integration with other vendors. IBM doesn't integrate well with products from China, like Huawei. Many Middle Eastern customers are switching to Huawei from American vendors like Cisco because of the price. In most RFPs, Huawei wins because it costs less."
"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

"It is very expensive."
"The solution is priced fairly, there is a license for the solution, and we pay annually."
"There is a license required for this solution. There are some limitations depending on what license you purchase."
"Pricing and licensing are competitive. Their new licensing options allow logs to bypass the correlation engine for a flat rate, which is also appealing for log data that is compliance-driven for a small amount of money."
"It is cheaper than ArcSight."
"The price could be better. I bought a subscription for three years."
"I think that the price is fair, but we can always say that the price could be cheaper."
"There is a license required for this solution."
"It’s a single license platform."
