vCISO (Fractional CISO)

A vCISO, or virtual or fractional Chief Information Security Officer, is an experienced security executive who runs your security program on a part-time or contract basis instead of as a full-time hire. The vCISO owns policies, controls, risk decisions, audits, and board reporting. It gives a company executive security leadership without a six-figure salary.

In practice

A vCISO is the named person on customer security questionnaires, in regulator correspondence, and in the board deck. That accountability is often the actual deliverable buyers and auditors care about.

The model fits companies that have outgrown ad hoc security but cannot justify a full-time CISO yet. The vCISO sets the program direction and cadence, then hands day-to-day execution to internal staff or specialist partners.
