Fractional CISO salary · day rate, retainer and annual equivalent
What a fractional CISO earns, by the day, the month and the year
A fractional CISO salary is a day rate or a monthly retainer, not a salary.
Optima Europe’s 2026 benchmarks put the fractional CISO day rate at £1,200–£2,000, and two to three days a week at £8,000–£18,000 a month.
Cypro puts a virtual CISO (vCISO) at £1,200–£2,500 a day, or £3,000–£15,000 a month.
The client pays only for the days agreed.
When you hire a fractional CISO through us, we send a shortlist of 3–5, each with day rate, days a week, availability and IR35 position set out.

Fractional CISO jobs on the board
Roles on the board: fractional and virtual CISO
Fractional Quest is a fractional recruitment agency: send a Fractional CISO brief and we come back with a shortlist of three to five vetted candidates.
01/ the cross
Where a permanent hire becomes cheaper.
Move the day rate and the days a week: the rising line is a month of part-week cost, the flat line a permanent hire’s month. Where they cross, the seat should go full-time.
At 2.4 days a week a permanent hire costs less.
Our arithmetic. Permanent a month = the salary ÷ 12 plus 15% employer NI, plus the 30% search fee spread over 12 months — the calculator’s inputs. Hover, tap or use the arrow keys for each step.
Permanent = the £135,250 Robert Half 2026 median salary. The full calculator below adds the months, the totals and the currency tabs.
- The fractional CISO at 2 days a week never passes permanent inside 24 months.
- Interim passes permanent at month 3.
Our arithmetic, cumulative. Permanent = the salary’s 30% search fee in month 0, then salary ÷ 12 plus 15% employer NI each month. Interim = the midpoint of the published interim band (£1,250 a day, Barclay Simpson) × 5 days × 4.33 weeks. Hover, tap or use the arrow keys for each month.
02/ the route
Fractional, interim or permanent?
Four taps. The answer names the route for the seat and the page that covers it.
The route · Fractional
A fractional CISO.The work fills part of the week, so buy the days it needs.
A fractional CISO holds the seat on agreed days for as long as the seat is needed, and works for other clients on the rest.
The route · Interim
An interim CISO.The work fills the week, and it has an end: a programme, a cover, a transaction.
An interim CISO takes the seat full time for that stretch and hands it over when it is done.
The route · Interim, then permanent
Interim now, a permanent CISO after.The seat is full time and long term, and the need is now.
An interim CISO holds it while the permanent search runs, so the seat is not left empty.
The route · Permanent
A permanent CISO.A full-time seat that sits at the table for years is a permanent hire.
There is time to run a search, so run one.
03/ the role
What a fractional CISO is paid for
A fractional CISO holds the security seat for part of the week, on an ongoing basis: the strategy, the risk register, the board report, the certification programme and the call when something goes wrong.
A virtual CISO, or vCISO, is the same arrangement delivered mostly remotely.
For the role itself, see fractional CISO.
The pay follows the days.
Optima Europe publishes £1,200–£2,000 a day for fractional and interim CISOs, and £8,000–£18,000 a month for two to three days a week.
Cypro publishes £1,200–£2,500 a day for a vCISO, with retainers of £3,000–£6,000 a month for smaller businesses taking 4–6 days a month.
The board is buying accountability, not hours.
The government’s Cyber Governance Code of Practice sets out what directors should do to govern cyber risk, and the NCSC’s Cyber Security Toolkit for Boards explains how to put it into effect.
A fractional CISO on a few days a month should report against it as a full-time one would.
04/ scope
What moves a fractional CISO’s rate
Days committed
The retainer scales with the days.
Cypro puts 4–6 days a month at £3,000–£6,000, and its full band at £3,000–£15,000 a month.
Optima Europe puts two to three days a week at £8,000–£18,000 a month.
Sector and regulation
Cypro says rates above £2,000 a day typically reflect specialist domains such as financial services, healthcare or M&A due diligence.
The framework the seat must deliver moves the scope too.
Cyber Essentials is the government-recommended minimum standard, built on five technical controls.
ISO/IEC 27001 sets the requirements for a full information security management system.
The NIST Cybersecurity Framework helps organisations understand and improve how they manage cyber risk.
A personal data breach can also bring a duty to report it to the regulator: the ICO’s guide to personal data breaches sets out when and how.
Credentials and track record
Cypro links the top of its band to CISSP or CISM credentials and FTSE-level experience.
The UK Cyber Security Council, the profession’s Royal Charter body, awards professional titles up to Chartered.
Ask for the incident they led and the board paper they wrote, not only the letters after their name.

Our arithmetic, indicative. Permanent = the £135,250 Robert Half 2026 median salary pro rata for the same months, plus 15% employer NI, plus a 30% search fee on the annual base (UK retained search runs 25–35%, Headhunters.co.uk). Excludes pension, bonus and equity.
06/ the week
How a week divides.
The days you buy are yours; the rest of the week goes to other clients. Move the days a week in the calculator above and the week redraws.
Illustration only: one way a fractional CISO’s week can divide at 2 days a week for you. Each block is half a day.

08/ rates by commitment
Fractional CISO salary by days committed
Day rates and monthly retainers as each source publishes them. Optima Europe is a recruiter; Cypro sells a vCISO service. The annual column is the source’s own figure where it gives one; otherwise our arithmetic (monthly × 12), labelled.
09/ economics
Day rate or retainer: what the fee has to cover
A fractional CISO’s fee is gross income to their own company.
From it they fund their pension, holidays, insurance, equipment, training and certifications, and the days between clients.
That is why a day rate looks high next to a salary divided by working days.
Tax status is a separate question from price.
It depends on how the engagement runs in practice: under the off-payroll working rules (IR35), a medium or large client makes the status determination; for a small client outside the public sector, the CISO’s own company decides.
HMRC’s CEST tool can help, and our IR35 guide sets out the tests.

11/ fractional ciso day rate
Fractional CISO day rate: the unit of pay
The published fractional CISO day rate runs from £1,200 to £2,000 in Optima Europe’s 2026 benchmarks, and from £1,200 to £2,500 for a vCISO in Cypro’s guide.
Cypro says rates above £2,000 typically reflect financial services, healthcare or M&A work.
Both sources also publish monthly retainers for a set number of days, which gives the client a predictable cost.
Two to three days a week comes to £8,000–£18,000 a month on Optima Europe’s figures, and Cypro’s retainers run from £3,000 to £15,000 a month.
For the hourly view, see fractional CISO hourly rate; for what a whole engagement costs a business, see fractional CISO cost.
12/ virtual ciso salary
Virtual CISO salary: what a vCISO earns
A virtual CISO salary is a retainer in the same way.
Cypro puts UK vCISO retainers at £3,000–£15,000 a month, and £40,000–£120,000 a year at 5–10 days a month.
Smaller businesses taking 4–6 days a month sit at £3,000–£6,000.
What the vCISO keeps depends on how many clients they hold and how many days each takes.
No source we have checked publishes a verified figure for a vCISO’s total annual income across clients, so we do not give one.
The model is now tracked in the interim market too: the Institute of Interim Management’s 2026 survey asked interim managers, for the first time, whether their last assignment was delivered fractionally.
13/ compared
Against a permanent salary and an interim day rate
A fractional fee does not compare one for one with an employee’s pay or a full-time contractor’s.
A permanent CISO is paid a salary plus bonus, pension and employer’s National Insurance; an interim CISO is paid a day rate for full-time cover over a fixed term.
Our CISO salary and interim CISO salary pages set out each, source by source.
Compare the annual cost of the days you need, not the day rate against a salary.
