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.

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.

The initial setup phase is very easy and user-friendly
I had tried Kaspersky a long time ago. I think it is available only in India. I don't know for sure. I have used that one for a couple of years, but I didn't like it, and that is the only reason I went back to Norton. Kaspersky was not safeguarding me in all aspects. I had seen some loopholes in the tool, so that is the only reason I went for Norton. The only thing I like about Kaspersky is that it supports the mobile version.
