Room For Improvement

IBM Security QRadar users seek improved upgrades, integrations, user interface, cost efficiency, AI features, and better threat detection.
SentinelOne Singularity AI SIEM requires improvements in performance, customization, integrations, automation, pricing, and clearer AI insights.
We receive logs from different types of devices and need a way to correlate them effectively.
Network and Security Architect at Deutsche Telekom
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
Information Security Analyst at Banglalink
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Cyber Security Architects at VaporVM
The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things.
Associate Vice President at Novac Technology Solutions
The interface flickers frequently, and sometimes it does not load properly.
IT Security Analyst at a tech consulting company with 11-50 employees
Whenever OT security comes into the picture, the customers do not allow us to integrate their OT devices on a cloud. It should be available on-premises because the OT SIEM market, in the India market for instance, is something around a four to eight billion dollar market.
Vice President Cyber Security Practice Head at orbit techsol w pvt.ltd
 

Setup Cost

IBM Security QRadar is costly but valuable, priced per EPS/FPS, and cheaper than Splunk yet pricier than other SIEMs.
SentinelOne Singularity AI SIEM offers a value-driven package with bundled services; its advanced capabilities justify slightly higher costs.
Splunk is more expensive than IBM Security QRadar.
Cyber Security Architects at VaporVM
It was costly mainly because of the value you can get right now compared to other solutions.

It depends on how much you want to spend.
Strategic Account Executive at a computer software company with 51-200 employees
I find SentinelOne's pricing to be reasonable and competitive.

IBM Security QRadar gives the opportunity to improve the time to market of the releases with a great evaluation of cybersecurity breaches.
Strategic Account Executive at a computer software company with 51-200 employees
Compared to ArcSight, Splunk, or any other SIEM tools where you need their processing language such as structured query language, SPL, and in Sentinel there is KQL query languages, IBM Security QRadar doesn't require reliance on query languages.
SOC Engineer at a outsourcing company with 10,001+ employees
We finally have visibility into things that were never visible before.
IT Security Consultant at Systemhaus for you GmbH
It employs a combination of AI and ML to check for viruses or any other malicious processes, including fileless attacks.

Featured Reviews

HarshBhardiya - PeerSpot reviewer
SOC Engineer at a outsourcing company with 10,001+ employees
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.
Dev Reshwal - PeerSpot reviewer
Technical Support Executive at Softcell Technologies Limited
Automation has reduced workload and real-time monitoring provides faster incident response
SentinelOne Singularity AI SIEM is the best, but sometimes the dashboards are a little simple compared to other tools. The custom dashboard is not available in their features. Therefore, I would suggest adding the custom dashboard for any of our requirements. The AI-driven analytics from SentinelOne Singularity AI SIEM has not affected our ability to reduce false positives. SentinelOne Singularity AI SIEM has affected my SOC's efficiency in investigating alerts and responding to incidents. If we receive any alerts, we can observe what activity is being done. We can see if it is malicious or something suspicious, or a true positive. We can analyze the path, the hash, and whether the signature is verified or not. We can see if it is an alert triggered by any engine. We can see the source of this. We will do that type of analysis and raise it to the client side. Also, if I identify anything suspicious or malicious in the alert, I will forcefully kill and quarantine it immediately.
