What a fractional CISO actually does in 2026 — four defining elements
The role against the current regulatory backdrop
A fractional CISO provides the security leadership function that a permanent CISO would — strategy, governance, risk management, compliance, board communication, incident readiness, vendor oversight — but on 1–3 days per week across multiple clients.
Cyber Security and Resilience Bill readiness
AI as both threat vector and governance obligation
Supply chain security as a first-class concern
Cyber insurance as a control-driving force
When companies hire a fractional CISO — seven scenarios
The most common engagement triggers
The case for a fractional CISO is almost always specific. The most common triggers fall into seven patterns.
Cyber Security and Resilience Bill readiness (3–12 months, £1,200–£1,800/day, 2–3 days/week)
SOC 2 or ISO 27001 certification preparation (4–9 months, £1,000–£1,500/day, 2 days/week)
Post-breach or post-incident (3–12 months, £1,500–£2,500/day, 3–5 days/week initially)
Cyber insurance renewal or new placement (2–4 months, £1,000–£1,500/day, 2 days/week)
FCA-regulated firm under SMCR (ongoing, £1,500–£2,500/day, 2–3 days/week)
Supply chain security response to customer demand (3–6 months, £1,200–£1,800/day, 2 days/week)
M&A and investment due diligence (8–16 weeks, £1,500–£2,000/day, 2–4 days/week)
How to evaluate a fractional CISO candidate — six essential checks
What to look for beyond the CV
Evaluating a fractional CISO is substantially different from evaluating a security consultant or a permanent CISO candidate. The signal-to-noise ratio is different, the references that matter are different, and the skills that predict success in multi-client portfolio work are not always visible on a standard security leadership CV.
Depth of direct CISO experience, not security leadership adjacent to CISO
Certifications calibrated to credibility, not to skills
Reference check prior boards and prior CEOs, not prior engineering leaders
Regulatory fluency specific to your context
Portfolio management honesty
Incident response track record with specifics
