The fractional model
Fractional CISO services for UK businesses
A Fractional CISO is a senior security leader who joins your business for a set number of days each month: embedded in your leadership team, accountable for security strategy, and shared across a small number of clients rather than employed full time.
How it works
A real leader, a fraction of the time
Embedded in your leadership team
Your fractional CISO works set days each month inside your business: attending leadership meetings, chairing the security committee and building relationships with the people who own the risks.
Days per month, matched to need
Most engagements run one to four days a month. Compliance pushes, funding rounds and incidents flex the days up; steady state flexes them down. You are never paying for a full-time seat that the workload does not justify.
Continuity without employment risk
The same named leader month after month, without recruitment fees, notice periods or single-point-of-failure risk. If your fractional CISO is ever unavailable, the CyPro bench stands behind them.
Accountable for outcomes
A prioritised roadmap, measurable risk reduction and audit-ready evidence. Fractional means part-time presence, not part-time accountability.
The work itself spans the same six areas as every engagement we run: see what's included for the full specification.
Is it for you?
Who the fractional model suits
- Scale-ups whose customers and investors now expect a named security leader
- Regulated businesses that need credible security ownership between audits
- Companies replacing a departed security lead without rushing a permanent hire
- Boards that want security represented properly at leadership level
Cost, plainly
Fractional engagements run at £2,500 to £5,000 per month depending on days and scope. Compare that with UK market day rates of £1,200 to £2,500 for senior security contractors, or around £255,000 a year all-in for a full-time CISO, and the model explains itself.
See the pricing tiersSame leaders, different label
Fractional CISO, Virtual CISO and CISO as a Service describe the same senior leadership in different engagement shapes. Whichever fits, the person is a named CyPro partner or senior practitioner with real CISO experience behind them.
Flexible by design
The number of days flexes with your needs: scale up ahead of an audit, a certification push or a funding round, then back down once the pressure passes. There are no recruitment fees and no notice periods to manage.

Fractional CISO FAQs
What is a Fractional CISO?
A Fractional CISO is a senior security leader who joins your business for a set number of days each month: embedded in your leadership team, accountable for security strategy and risk, and shared across a small number of clients rather than employed full time.
How much does a Fractional CISO cost in the UK?
Our fractional engagements run at £2,500 to £5,000 per month depending on days and scope. UK market day rates for senior security leaders typically sit between £1,200 and £2,500, which makes a monthly fractional engagement dramatically cheaper than either contracting or a £255,000 all-in full-time hire.
Fractional CISO or Virtual CISO: which do I need?
They are the same seniority delivered in different shapes. Choose fractional if you want a leader visibly embedded in your business on set days. Choose the virtual model if you want flexible, largely remote leadership with on-demand access. We deliver both, with the same named practitioners.
