Identity is the new perimeter. A robust ESA prioritizes identity governance to ensure that only authorized users, devices, and workloads can access corporate resources.

SABSA uses a layered approach to ensure that high-level business goals are traceably linked to specific technical configurations. Destination Certification Perspective Contextual

Existing technical debt can make it difficult to enforce a clean, top-down architecture. Address this by adopting a phased migration approach, wrapping legacy systems in modern security perimeters until they can be decommissioned.

The final layer focuses on day-to-day management, monitoring, and maintenance. It defines the operational workflows, patch management schedules, incident response playbooks, and continuous compliance auditing processes. Core Components of a Modern ESA Identity is the new perimeter
