•     Lead end-to-end network and security architecture across global platforms ensuring secure, high-performing, fault-tolerant, and resilient environments.
 
Microsegmentation & Zero Trust Responsibilities:
•     Architect and implement microsegmentation strategies across data center, campus, and cloud environments to limit lateral movement and enforce least-privilege access.
•     Design and operationalize Zero Trust Architecture (ZTA) principles, integrating identity, application, and network-based policy enforcement.
•     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.
•     Conduct and support internal and external security audits and compliance assessments.
•     Maintain awareness of emerging threats and update policies accordingly.
•     Develop and manage policies, processes, and procedures ensuring reliability, availability, and security of network systems.
•     Manage and optimize Security Information and Event Management (SIEM) systems.
