Featured Reviews

Syed Abid  - PeerSpot reviewer
Advanced threat protection secures diverse workloads with cost-effective deployment
If I need logs and don't have local storage bundled with Defender, I need to add workspace and log analytics, which is costly for storing logs of 2 GB, 5 GB, 10 GB. A default storage of 5 GB for logs should be included with Defender. There are limitations in whitelisting folders and files, and the whitelisting feature for Defender threat protection was deprecated. A straightforward feature for this should be added.
Asim Naeem - PeerSpot reviewer
It integrates well with other platforms, is user-friendly, and is stable
SentinelOne Singularity Complete integrates with our other security solutions, correlating data from NDR, ADR, SIEM, and XDR tools. All this information is consolidated within SentinelOne, providing a centralized access point. SentinelOne Singularity Complete has helped us streamline our security operations by consolidating multiple solutions into a single platform. We are currently in the process of acquiring a threat intelligence platform to complete our security stack. We use Ranger to monitor our network and track connected devices. This is crucial because it helps us quickly identify unauthorized machines connected to our infrastructure, including personal devices. We have additional security measures in place, but Ranger provides an extra layer of protection. It also alerts us if the SentinelOne Singularity Complete agent is missing from any new or existing machines, allowing us to take appropriate action. SentinelOne Ranger's agentless and hardware-independent nature is crucial for our environment with 26,000 endpoints, as manual management of such a large number would be extremely challenging. Ranger uses a multi-layered approach to prevent vulnerable devices from being compromised. We employ scanners, network configurations, and a risk scanner to assess devices, endpoints, servers, and cloud infrastructures. Vulnerability reports and timelines for remediation are shared with device owners or custodians. This proactive strategy enables us to address vulnerabilities efficiently and secure our infrastructure. SentinelOne Singularity Complete has significantly enhanced our security posture. While no system is impenetrable, this solution has brought us closer to achieving a high level of protection, ensuring we maintain at least a 90 percent security level. Our team is dedicated to refining alerts and eliminating false positives from our solutions. Additionally, a team is responsible for identifying and excluding alerts from the solution. We can manually expedite this process by reviewing these elements and utilizing our security tools. We have been able to reduce the alert volume by 20 percent. Our 30-member Security Operations Center team has been able to redirect their focus to other tasks due to the time saved after implementing SentinelOne Singularity Complete. SentinelOne Singularity Complete has helped us improve our mean time to detect threats, which we accomplish using the Vigilance service for detection and response. SentinelOne Singularity Complete has helped us decrease our organizational risk. We utilize the Security Scorecard to manage our security posture, which has remained steady at 90 percent.
