• Develop security classification models for applications, data, workloads, and environments.
• Create reusable policy design patterns, design authority documentation, and reference architectures.
• Define review and approval processes for segmentation policies, facilitate architecture design workshops, and produce executive-level decision records.
• Microsegmentation Architecture
• Design workload segmentation models leveraging VMware NSX / vDefend to control east-west traffic patterns.
• Create application-centric segmentation methodologies and define standards for workload grouping, policy inheritance, and rule management.
• Cloud & Hybrid Security Architecture
• Define Azure segmentation architecture, security zoning, and cloud network security guardrails.
• Ensure seamless alignment between data center and cloud-based security controls, establishing strict security requirements for hybrid connectivity.
• Discovery & Current-State Assessment
• Assess existing firewall policies and segmentation controls to identify opportunities to reduce complexity and improve policy effectiveness.
• Document current-state architecture, conduct gap analyses, and produce prioritized remediation recommendations.

Qualifications
