Fractional CISO / Part-Time Security Director — London at Fractional Quest
About This Role
About This Fractional CISO Opportunity in London
We are seeking an experienced Fractional CISO (also known as a Part-Time Security Director) to provide strategic cybersecurity leadership to high-growth companies across London. This is a portfolio role offering 1-3 days per week, with remote and hybrid working options available.
According to the National Cyber Security Centre (NCSC), cyber threats to UK businesses have increased significantly, yet many SMEs lack dedicated security leadership. London's position as a financial and tech hub creates exceptional demand for experienced security executives.
What Does a Security Director Do in a Fractional Capacity?
As a Part-Time CISO, you will establish and mature cybersecurity programmes while managing risk at board level. ISC2 recognises that fractional security leadership enables organisations to access CISO-calibre expertise during critical growth phases.
Key responsibilities include security strategy and roadmap development, risk assessment and management frameworks, compliance and regulatory adherence (GDPR, ISO 27001, SOC 2), incident response planning and crisis management, security awareness and culture building, and vendor security assessments and due diligence.
Day Rates in London
This role offers day rates of £900-£1,500 depending on sector complexity and regulatory requirements. According to Glassdoor UK, fractional CISOs working 2-3 days per week can achieve annual earnings of £180,000-£350,000.
ISACA reports a critical shortage of senior security professionals, with demand outstripping supply by 3:1 in the UK, driving premium rates for experienced CISOs.
Who Should Apply?
Ideal candidates will have 15+ years in information security with experience building security programmes from the ground up. CISSP, CISM, or equivalent certification is expected. Experience in regulated industries (financial services, healthcare) is highly valued.
Understanding of ICO requirements and FCA operational resilience expectations is important for many London-based roles.
