FRACTIONAL CISO & SECURITY LEADERSHIP
Your board needs assurance. Your regulators need evidence. Your business needs a leader who has done this before – at scale, under pressure, in the sectors that carry real risk.
A Fractional CISO is a senior, board-credible security leader who works with your organisation on a flexible, part-time basis – providing the strategic oversight, regulatory confidence, and leadership capability of a full-time CISO, without the overhead of a permanent hire.
It is not consultancy. It is not a report. It is accountable leadership – embedded in your business, present in your boardroom, and answerable to your stakeholders.
Clear, confident reporting to your board and audit committee. We translate technical risk into commercial language your leadership can act on.
ISO 27001, Cyber Essentials Plus, DORA, NIS2, SRA, FCA – we ensure your organisation is evidenced and audit-ready across every relevant framework.
A multi-year security strategy aligned to your business objectives – not a generic framework. Prioritised, resourced, and owned.
When a breach occurs, you need someone who has stood in that room before. We provide on-call incident leadership and post-incident review.
From due diligence on M&A targets to ongoing supplier assurance programmes – we manage the risk that sits beyond your perimeter.
Building security awareness from the boardroom to the front desk. We develop the people, processes, and culture that make security sustainable.
Our Fractional CISO service is designed for organisations that carry regulatory, reputational, or commercial risk they cannot afford to mismanage – but who do not need, or cannot justify, a full-time security hire.
● Law Firms & Legal Services
SRA obligations, client data, and AI adoption demand credible security leadership – not a checklist.
● Listed & Regulated Businesses
FCA, NIS2, DORA, and investor scrutiny require board-level security governance that stands up to external challenge.
● Professional Services Firms
Accountants, consultants, and advisors holding sensitive client data face growing cyber threat and client due diligence pressure.
● Private Equity & Portfolio Companies
Security risk is deal risk. We provide pre-acquisition assessment and post-deal security uplift across PE portfolios.
