• Collaborate with application owners to discover, validate, and map application dependencies to enable policy-driven segmentation via firewall rules and security zones.
• Define and enforce granular security policies using zone-based segmentation, VRFs, and SRX policy constructs across hybrid environments.
• Integrate segmentation with firewalls, SIEM, IAM, EDR/XDR, and cloud-native controls for unified policy enforcement.
• Lead adoption and standardization of Juniper SRX as the primary segmentation enforcement platform across enterprise environments.
• Develop segmentation governance models, policy lifecycle management, and compliance alignment (CIS/NIST/Zero Trust frameworks).
