Featured Reviews

Nasseer Qureshi - PeerSpot reviewer
Pre Sales Consultant at Redington Group
Delivers seamless and secure remote access while enhancing security posture
Check Point Harmony SASE (formerly Perimeter 81) offers strong features, but there are areas that could be improved. One area for improvement is integration with third-party identity providers. It works with standard SAML and SSO, but we would prefer deeper integrations with solutions such as Ping for more advanced identity-based policies. Additionally, a mobile-specific client or lightweight agent would be helpful for securing access from smartphones, especially in BYOD environments. We would appreciate more granular reporting and analytics, including better drill-down capabilities to investigate specific users or app activity. The logs are comprehensive, but filtering them can sometimes feel messy. The user interface on the management portal could be more intuitive, especially when managing multiple sites or remote offices. Some of the policy configuration steps are nested and could be streamlined.
Vaibhav Mahendra Kolhe - PeerSpot reviewer
Soc Analyst at Softcell Technologies Limited
Automation has reduced alerts and freed the soc team to focus on faster incident response
Regarding mean time to respond, the improvements I see with SentinelOne Singularity Complete are that genuine files also get alerts. We are getting false positives, but we are also getting genuine true positive alerts. The improvement will be deep visibility because as I am using Splunk as a SIEM, I compare deep visibility with Splunk, but deep visibility has limited access with only a 14-day policy to retain logs. The improvement will be in overall policy management. The third point will be the complexity of policies. If we want some endpoints to use only USB or if we need to block USB on some points, the policy management is very complex. The fourth point will be that Mac OS and Linux don't have the rollback policy; that policy is only for Windows. These four points are improvements if SentinelOne Singularity Complete can address them. Data privacy and security when utilizing Purple AI is crucial for SentinelOne Singularity Complete, and SentinelOne Singularity Complete lacks in data security. Data security is very important in this world. In my organization, if we deploy SentinelOne Singularity Complete and we have integrated all the firewalls, all devices, and AWS devices to SentinelOne Singularity Complete, logs will be forwarded to SentinelOne Singularity Complete through SentinelOne Singularity Complete. However, SentinelOne Singularity Complete doesn't have data security solutions such as Forcepoint DLP or 48 layer; SentinelOne Singularity Complete doesn't have that DLP solution. From the data security point of view, SentinelOne Singularity Complete is not good.
