The Growing Need for Security Leadership
Cybersecurity has evolved from a technical concern to a board-level strategic priority. Ransomware attacks make headlines weekly. Data breaches trigger regulatory investigations and reputational damage. Supply chain compromises cascade through interconnected businesses. Every organisation, regardless of size, faces sophisticated threats that demand executive-level security leadership.
The Chief Information Security Officer (CISO) is the executive responsible for an organisation's information security strategy. They ensure that security considerations inform business decisions, that risks are identified and managed, and that the organisation can respond effectively when incidents occur.
In the UK, full-time CISOs command salaries between £120,000 and £200,000—investment levels that exceed what many mid-market companies can justify. The fractional model is changing this equation, making CISO-level security leadership accessible to organisations that need it most.
What Is a Fractional CISO?
A fractional CISO is an experienced security executive who provides strategic security leadership on a part-time, ongoing basis. Rather than dedicating full-time capacity to a single organisation, they typically work 2-4 days monthly with each client, providing the executive oversight that effective security requires.
This isn't security consulting or penetration testing. A fractional CISO operates at the strategic level—setting security direction, advising leadership, managing risk, and ensuring that security capabilities mature alongside business growth.
Key responsibilities include:
- Developing and overseeing information security strategy
- Advising the board and executive team on security risks
- Establishing security governance frameworks and policies
- Overseeing security operations and incident response capabilities
- Managing regulatory compliance (GDPR, PCI-DSS, ISO 27001)
- Evaluating and selecting security technologies and vendors
- Building security awareness culture across the organisation
- Representing security in strategic business decisions
When Do You Need a Fractional CISO?
Several indicators suggest your organisation would benefit from fractional CISO leadership:
Growing Attack Surface: As you add cloud services, remote workers, and third-party integrations, your security complexity increases. Someone needs to think strategically about this expanding landscape.
Regulatory Requirements: Industries facing regulatory scrutiny—financial services, healthcare, government contractors—need demonstrable security governance that goes beyond technical controls.
Customer and Partner Expectations: Enterprise customers increasingly require security attestations. A fractional CISO can establish the frameworks and certifications that open these doors.
Board and Investor Pressure: Sophisticated boards want security briefings and assurance. Investors conduct security due diligence. A fractional CISO provides credible representation.
Security Incidents or Near-Misses: If you've experienced security events that highlighted gaps in your approach, a fractional CISO can assess the situation and implement improvements.
Benefits of a Fractional CISO
Executive Security Expertise at Accessible Cost
A fractional CISO typically costs £40,000-80,000 annually for 2-4 days monthly engagement. Compare this to £150,000-250,000 for a full-time equivalent including benefits and overhead. You access genuine CISO capability at a fraction of the investment.
Immediate Security Maturity
Experienced fractional CISOs have built security programmes multiple times. They know what frameworks to implement, what policies to establish, and how to prioritise limited resources. This experience accelerates your security maturity dramatically.
Threat Landscape Awareness
Fractional CISOs work across multiple organisations, maintaining current awareness of threats, attack patterns, and defensive innovations. They bring real-time threat intelligence that single-company CISOs may lack.
Regulatory and Compliance Expertise
Navigating GDPR, achieving ISO 27001 certification, or preparing for regulatory examinations requires specific expertise. Fractional CISOs have guided organisations through these processes repeatedly.
Vendor and Technology Independence
Unlike security vendors who recommend their own products, fractional CISOs provide independent guidance on technology decisions. They recommend solutions based on your needs, not their commercial interests.
How to Hire a Fractional CISO
What to Look For
Prioritise candidates with genuine CISO or Head of Security experience—not just security engineering or analyst roles. Verify certifications such as CISSP, CISM, or SABSA. Confirm experience in your regulatory environment and with organisations of similar scale.
Assess their ability to communicate security concepts to non-technical audiences. CISOs must translate technical risks into business terms for boards and executives. Request examples of board presentations or risk reports they've produced.
Key Questions to Ask
- What security programmes have you built, and what maturity improvements resulted?
- How do you approach security strategy for a new organisation?
- What compliance frameworks have you implemented?
- How do you handle security incidents in a fractional capacity?
- What security metrics do you track and report to leadership?
Red Flags to Avoid
Be cautious of candidates who focus exclusively on technical controls without connecting to business risk. Avoid those who advocate fear-based approaches or unrealistic security investments. Question anyone who dismisses the importance of security culture and user awareness.
Protect Your Organisation
Security leadership isn't optional in today's threat environment. The question is whether you address security strategically or reactively. A fractional CISO provides the executive oversight that transforms security from a technical function into a business enabler.
