• Collaborate with application owners to discover, validate, and map application dependencies to enable policy-driven segmentation.
• Define and enforce granular security policies using label/tag-based segmentation approaches across hybrid environments.
• Integrate microsegmentation with firewalls, SIEM, IAM, EDR/XDR, and cloud-native controls for unified policy enforcement.
• Lead adoption of microsegmentation platforms (e.g, Guardicore/Akamai Segmentation).
• Develop segmentation governance models, policy lifecycle management, and compliance alignment (CIS/NIST/Zero Trust frameworks).

Core Network Security Responsibilities

• Participate in network security design reviews and ensure all implementations meet enterprise security standards.
• Analyze business requirements to design and implement security across data centers, campus networks, and hybrid environments.
• Provide ongoing risk metrics, control effectiveness tracking, and security posture reporting.
