Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.

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.

"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
"SentinelOne Singularity AI SIEM has improved our overall security posture and is reducing the workload on the SOC team."

Cons

"It is quite good, but the only downside is that it is costly."
"The AI-generated investigations can occasionally require manual validation for complex incidents."
