ABHISHEK_SINGH - PeerSpot reviewer
Senior Process Expert at A.P. Moller - Maersk
Gained full visibility and streamlined threat detection through behavior-based insights and AI integration
Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.
Kalpesh Pawar - PeerSpot reviewer
Technical Head Cloud Services at Softcell Technologies Limited
Unified threat visibility has reduced incident impact and streamlines response across our endpoints
From a customer or SOC perspective, the best features Microsoft Defender for Endpoint offers are the EDR with deep telemetry, which helps us with continuous behavioral monitoring. The automated investigation and remediation feature includes auto-isolation, file quarantine, and incident-level correlation. The advanced hunting KQL-based feature along with Attack Surface Reduction and vulnerability management proactively hardens exposures and provides visibility to reduce attack paths before exploitation. The advanced hunting and vulnerability management features in Microsoft Defender for Endpoint help my team day to day by allowing us to utilize Advanced hunting KQL for proactive threat hunting and validation of alerts, querying process trees, lateral movement, and IOC swipes across all endpoints in seconds. The vulnerability management feature gives us a real-time exposure view with risk-based prioritization. We align it with patching cycles and use security recommendations to reduce attack surface before exploitation. Device isolation and live response provide real operational value. This capability allows a SOC to instantly isolate compromised hosts and run remote forensics or commands without user impact, which is critical during active incidents.
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.
