The UK Part-Time CISO Market

The part-time CISO model (also known as fractional CISO or vCISO) has become increasingly popular as companies recognise they need senior security leadership without the full-time cost. This creates opportunities for experienced security professionals to build portfolio careers.

Unlike interim CISO roles which are full-time for a fixed period, part-time CISO positions offer ongoing engagement typically 1-3 days per week. Many fractional CISOs work with multiple clients simultaneously.

Who Hires Part-Time CISOs?

  • SMEs - Companies needing security governance
  • Startups - Companies building security foundations
  • Regulated businesses - FCA, healthcare, fintech compliance
  • PE portfolio companies - Businesses needing security oversight
  • Scale-ups - Growing companies needing cyber maturity

FAQ

Common Questions About Part-Time CISO Jobs UK

A part-time CISO (also called fractional CISO or vCISO) is a Chief Information Security Officer who works with companies 1-3 days per week on an ongoing basis. This model provides senior security leadership without the full-time commitment or cost.
Part-time CISO day rates in the UK typically range from £1,000-£1,500 per day. For a 2-day per week engagement, annual costs are £100,000-£150,000 - significantly less than a full-time CISO package.
Most part-time CISO roles involve 1-3 days per week, with 1-2 days being common for SMEs. Many CISOs work with multiple clients to build a portfolio career.
The terms are often used interchangeably, along with 'virtual CISO' or 'vCISO'. All refer to senior security leaders working less than full-time, providing ongoing security leadership and compliance oversight.
SMEs, startups, scale-ups, and regulated businesses commonly hire part-time CISOs. They get experienced security leadership at a fraction of full-time cost - ideal for companies needing compliance and security governance.
