What should a fractional CISO do in the first 90 days?

The first 90 days should produce a risk view, control roadmap, evidence plan, and executive reporting cadence.

A good start includes reviewing critical assets, access, vendors, cloud configuration, policies, and existing incidents or near misses.

The output should help leaders decide what to fix now, what to monitor, and what can wait.

How should fractional CISO value be measured?

Measure value through reduced critical risks, faster customer diligence, better audit readiness, and stronger incident preparedness.

Security leadership should create visible progress. Examples include closed high-risk findings, completed access reviews, tested incident plans, and cleaner customer security responses.
