The perimeter moved into identity
Modern environments are stitched together by workforce accounts, service principals, API keys, and delegated trust. One overprivileged identity can bypass layers of otherwise sound infrastructure.
Start with high-impact paths
Prioritize administrative roles, non-human identities, stale access, recovery mechanisms, and the systems that can mint new credentials.
Good identity security makes normal work easy, privileged work deliberate, and abnormal behavior expensive.
