CISO as a Service
CISO as a Service is an outsourced, on-demand model that gives a board senior cybersecurity leadership without hiring a permanent chief information security officer. vCyberBoard Advisor delivers CISO as a Service to boards, executives and organisations across the European Union independent, remote and answerable to the board.
What CISO as a Service includes
CISO as a Service covers security strategy, the cyber-risk conversation with leadership, governance and reporting, regulatory readiness, and preparation for incident response and recovery. It is deliberately board-facing: the service translates technical exposure into decision-ready risk so directors can govern it like any other material business risk.
CISO as a Service versus a permanent CISO
Not every organisation needs a full-time CISO. CISO as a Service gives a board the same senior judgement and accountability at a fraction of the commitment and keeps it independent. Where a permanent CISO can become embedded in internal politics, an outsourced CISO remains an external, objective voice the board can trust to challenge management's reporting without conflict of interest.
Governance and regulatory leadership
European regulation now places accountability directly on management bodies. CISO as a Service helps the board evidence its obligations under NIS2, DORA and ISO/IEC 27001, and govern AI under the EU AI Act, turning compliance into a governance programme the board can own and defend.

How it relates to a virtual CISO
CISO as a Service and a virtual CISO (vCISO) describe the same idea senior security leadership delivered remotely and on demand. The terms are often used interchangeably; the model pairs the seniority of a CISO with the virtual cyber board advisor relationship for continuous counsel.
