Virtual CISO

What a virtual CISO does

A vCISO typically covers seven core areas, scaled to the organisation’s maturity and needs:

• Security strategy – designing and maintaining a cyber security strategy aligned with business objectives, regulatory requirements, and risk appetite. This includes selecting frameworks NCSC CAF, NIST CSF, ISO 27001) and setting a roadmap for maturity improvement
• Risk management – identifying, assessing, and prioritising cyber risks. Establishing risk registers, defining risk appetite with the board, and ensuring mitigation plans are resourced and tracked
• Compliance oversight – managing compliance with regulations and standards relevant to the organisation: GDPR, UK NIS Regulations, NIS2 (for EU operations), DORA (for financial services), Cyber Essentials, ISO 27001
• Board reporting – translating technical risk into business language for board members and non-technical stakeholders. Presenting security posture, incident trends, and investment cases in terms the board can act on
• Incident response planning – building and testing incident response plans, defining escalation procedures, and ensuring the organisation can respond effectively when an incident occurs. Often includes running crisis simulation exercises
• Vendor and supply chain security – assessing third-party risks, reviewing supplier security practices, and ensuring contracts include appropriate security requirements
• Security culture – driving security awareness across the organisation through training programmes, policy development, and embedding security into operational processes

When you need a virtual CISO

The vCISO model fits specific organisational profiles:

You need a vCISO if your organisation handles sensitive data or operates in a regulated sector, you have no dedicated security leadership, your IT team manages security alongside other responsibilities, the board is asking for cyber risk assurance and nobody is qualified to provide it, or you are preparing for ISO 27001 certification or a regulatory audit.

You probably don’t need a vCISO if your organisation already has a CISO or head of security, you need someone on-site full-time managing a large security team, or your security needs are purely operational (patching, monitoring) rather than strategic.

The middle ground is organisations that have outgrown ad-hoc security management but are not yet large enough to justify a £200,000 executive. A vCISO bridges that gap. Typically for 2 to 8 days per month, with the ability to scale up during incidents, audits, or board cycles.

vCISO vs managed security services

A vCISO and an MSSP (managed security service provider) are not the same thing:

	Virtual CISO	MSSP
Focus	Strategy, governance, risk, compliance	Operations, monitoring, alerting
Deliverables	Security strategy, board reports, risk registers, policies	SIEM alerts, threat detection, incident triage
Reports to	Board / CEO / CFO	IT Director / Security team
Engagement	Retained advisory days	Continuous monitoring service
Replaces	The strategic CISO role	The SOC / monitoring function

Many organisations need both. The vCISO sets the direction; the MSSP or [MXDR](/glossary/mxdr/) service executes the operational monitoring.
