• Design and implement both macro‑segmentation and micro‑segmentation strategies across network and application environments.
• Architect identity‑centric access controls based on user, device, and contextual risk signals.
• Drive integration of ZTNA with the enterprise security ecosystem (SIEM, SOAR, EDR, DLP, IAM).
• Design and implement automated remediation capabilities leveraging SOAR, orchestration platforms, and policy engines to dynamically respond to threats and non‑compliance.
• Establish and enforce security controls for AI‑enabled systems interacting within ZTNA frameworks, including model access controls, data protection, and monitoring of AI‑driven access behaviors.
• Conduct threat modeling and risk assessments across access pathways, segmentation boundaries, and AI‑integrated services.
• Lead vendor evaluation and selection for ZTNA, SASE, automation, and AI security technologies.
• Provide executive advisory and governance for Zero Trust and secure access initiatives.
