FAQ

Common Questions About Advisory CISO Jobs UK

An advisory CISO is a senior security professional who provides strategic cybersecurity guidance on a consultative basis. Unlike interim CISOs who take on full operational responsibility, advisory CISOs offer high-level counsel on specific challenges such as security strategy, risk assessment, compliance, or board reporting. They typically work fewer hours but bring deep expertise to critical security decisions.

Advisory CISO day rates in the UK typically range from £700-£1,000 per day, depending on experience, sector expertise, and complexity of the engagement. Specialist areas like financial services security or incident response can command rates of £1,000-£1,400/day. Advisory roles often involve fewer days per month than interim roles, making them cost-effective for specific strategic needs.

Advisory CISO engagements are typically structured around specific deliverables or time allocations (e.g., 2-4 days per month). The advisory CISO might review security strategy, attend board meetings, assess security posture, mentor security leaders, or provide guidance on compliance and regulatory requirements. Engagements can be ongoing retainers or project-based.

Advisory CISOs provide strategic counsel without operational responsibility, typically working 1-4 days per month on high-level guidance. Fractional CISOs take on part-time operational leadership (1-3 days per week), managing security teams and programs. Advisory roles suit companies with capable security teams needing strategic oversight; fractional roles suit those needing hands-on leadership.

Most advisory CISOs have 15+ years of security experience including prior CISO, Security Director, or VP Security roles. Essential qualifications include security certifications (CISSP, CISM, CRISC), experience with regulatory frameworks (ISO 27001, SOC 2, GDPR), and board-level communication skills. Many have sector-specific expertise in financial services, healthcare, or critical infrastructure.

The highest demand for advisory CISOs comes from: financial services (regulatory compliance, threat management), healthcare (patient data protection, HIPAA-equivalent), technology companies (product security, SOC 2), and regulated industries (critical infrastructure, government contractors).

Advisory CISO roles often fall outside IR35 due to their consultative nature, lack of day-to-day control, and project-based scope. However, each engagement must be assessed individually. Key factors include: no substitution restrictions, working for multiple clients, providing genuine advice rather than filling a role. Always obtain a status determination statement (SDS).

Advisory CISO hiring focuses on expertise fit and trust. The process typically includes: initial discussion with CEO/board about security challenges, assessment of relevant experience and certifications, discussion of working relationship dynamics, and agreement on scope and confidentiality. Decisions are often made within 2-3 weeks.

Yes, advisory CISO relationships often expand. Many advisory engagements lead to: increased scope (from advisory to fractional), board positions (security oversight), and referrals. The advisory model is excellent for building a portfolio of security leadership relationships.

Focus on: security programs built and matured, compliance certifications achieved, incident response experience, board-level communication skills, and sector expertise. Highlight your advisory approach and how you complement existing teams rather than replacing them.
