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.
Shivam Dhang - PeerSpot reviewer
IT Infrastructure & Cloud Manager at Softcell Technologies Limited
Unified security view has reduced incident response time and improves cross-domain threat hunting
From a customer perspective, given that we are using Microsoft Defender XDR at a company with multiple cloud environments, I would like to see more intelligent alert tuning. Sometimes we still get noise, so better prioritization would help. I also wish the advanced hunting interface was more streamlined, especially for large-scale queries. Finally, deeper integrations with third-party tools would help us get a more complete picture across our stack. Onboarding can be complex if Microsoft 365 identity and endpoints are not properly aligned. Initial setup requires good planning. Overall, the platform is strong, but onboarding should be planned according to your specific needs.

A highly stable and affordable solution for detecting and preventing security threats
The solution needs to provide better integration. We may receive things from email, network, or the machine itself. So we need a centralized system to get alerts or messages which are not available in the product. The solution must provide features to centralize the alerts received. It should provide integration with other Symantec products.
