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.

Advanced threat hunting saves significant time in tracking and responding to incidents
Microsoft Defender XDR could be improved with a lower price. My main suggestion would essentially be what Copilot is providing, which is a single pane of glass, so I don't have to go to different windows. That's just a workflow consideration for me. It would be great to have all the information centralized into one particular data app. If I need to open up extra ones, I can, however, I would appreciate a future where everything I need is right there on one single pane of glass. Beyond that, there's really nothing else I see that I would want Microsoft to improve.

Advanced threat prevention has strengthened incident response and customized security workflows
The biggest advantage of Trellix Endpoint Security Platform is the ATP solution, which provides advanced threat prevention. Machine learning algorithms are available in the product as part of the threat anti-malware, including predictive machine learning and behavioral analysis, which are integral to the anti-malware module of EPP. In terms of my experience with the machine learning algorithms for analysis and threat detection, we are analyzing logs provided by Trellix, but we are not able to conduct specific machine learning analysis on those logs. The automated response mechanisms in the products help with incident management because we have to create playbooks in Trellix console for automation, which we need to enable. The customizable dashboard of Trellix Endpoint Security Platform definitely contributes to the decision-making process, as we customize the dashboard according to customer requirements. When it comes to integration aspects, we are able to integrate Trellix Endpoint Security Platform with SIEM or SOAR solutions using the ePO console, which enhances threat detection capabilities. Reporting and analytics aspects have an impact on security posture assessment, as we are able to fetch reports in the ePO console customized according to customer requirements for downloading and sending via email.
