Fractional CISO Services

Board-level cybersecurity leadership for UK businesses — without the £200k+ salary.

What Is a Fractional CISO?

A fractional CISO — Chief Information Security Officer — provides board-level cybersecurity leadership to your business on a flexible, part-time basis. They take full accountability for your security strategy, cyber risk posture, compliance obligations, and incident response capability. A fractional CISO is not a technical engineer or a managed service provider: they are a senior leader who translates cyber risk into business language, owns security governance, manages security vendors, and ensures the board has accurate visibility of the threats facing the organisation. For UK SMEs, the fractional model makes enterprise-grade security leadership accessible without the overhead of a permanent CISO costing over £130,000–£200,000 per year.

When Should You Hire a Fractional CISO?

  • You are facing increasing cyber threats, a recent security incident, or regulatory pressure but lack senior security leadership to respond
  • You need to achieve a security certification — Cyber Essentials, ISO 27001, SOC 2 — and require an experienced leader to own the programme
  • Your board is asking questions about cyber risk and you need someone who can answer them authoritatively and drive the right actions
  • You hold sensitive customer data, operate in a regulated sector, or are subject to supply chain security requirements from enterprise customers
  • You are preparing for acquisition, investment, or contract tendering where security maturity will be scrutinised during due diligence
  • Your security spend is growing but lacks strategic direction — you need independent oversight of your security vendors and investments

What They Deliver

Cybersecurity Strategy & Roadmap

A pragmatic, risk-based cybersecurity strategy aligned to your business context, regulatory obligations, and evolving threat landscape. Covers the security controls, investments, and capabilities required to protect the business — prioritised by actual commercial risk rather than technical completeness or vendor preference.

Risk & Control Assessment

A structured assessment of your current security posture against best-practice frameworks — including Cyber Essentials, ISO 27001, and NIST CSF. Identifies critical gaps, quantifies risk in business terms, and produces a prioritised remediation roadmap the board can understand, own, and act upon.

Security Governance & Compliance

Establishment and ongoing management of security governance: policies, standards, audit schedules, and board-level reporting. Ensures your business meets its compliance obligations — GDPR, sector regulations, and customer contractual requirements — with clear accountability and appropriate documentation maintained at all times.

Incident Response Planning

Development of incident response playbooks, facilitation of tabletop exercises, and coordination of external vendor relationships. Ensures the business is genuinely prepared to respond to a cyber incident quickly and effectively — protecting operations, data, and reputation when a security event occurs.

Identity & Access Management

Senior oversight of identity and access management — MFA rollout, least-privilege access frameworks, privileged access governance, and full identity lifecycle management. Addresses one of the most frequently exploited attack vectors facing UK SMEs in a structured, proportionate, and commercially sensible manner.

Vendor & Supply Chain Security

Assessment and management of security risk across your supplier and technology vendor relationships. Includes security questionnaire frameworks, third-party risk assessments, and contractual security requirements — protecting your business from the increasingly common threat of cyber incidents originating through your supply chain.

Frequently Asked Questions

What does a fractional CISO do?

A fractional CISO provides board-level cybersecurity leadership on a part-time basis. They own the security strategy, cyber risk posture, compliance programme, and incident response capability for your business. Unlike a technical security engineer, a fractional CISO operates at the strategic level — translating cyber threats into business risk, managing security vendors, presenting to the board, and making the governance decisions that protect the organisation from financial, reputational, and regulatory harm.

A fractional CISO from Leadership Services ranges from £1,500 to £5,000 per month, depending on scope and the number of days required. This compares to a full-time CISO salary of £130,000 to £200,000 per year in the UK, plus employer on-costs, benefits, and recruitment fees. For most UK SMEs and mid-market businesses, the fractional model provides the board-level security leadership they need to manage cyber risk effectively at a fraction of the permanent hire cost.

These are complementary, not interchangeable. A managed security service provider (MSSP) delivers technical security tools and monitoring. A CISO provides the strategic leadership, governance, and commercial judgement to direct those services effectively. Without a CISO, many businesses spend on security technology without a coherent strategy, overpay for the wrong services, and lack the board-level accountability to manage security risk properly. A fractional CISO ensures your security investment is directed intelligently.

Yes. Supporting certification programmes — including Cyber Essentials, Cyber Essentials Plus, and ISO 27001 — is a common engagement type for Leadership Services’ fractional CISOs. They own the certification programme end-to-end: gap assessment, remediation planning, policy development, audit preparation, and coordination with certification bodies. Many clients achieve Cyber Essentials within three months and ISO 27001 within twelve months of engaging a fractional CISO.

Most engagements begin within one to two weeks of an initial consultation. There is no lengthy recruitment process, no notice period, and no extended onboarding. Leadership Services matches you with a fractional CISO whose sector experience and regulatory background are relevant to your business. They join your leadership team, conduct an initial security assessment, and begin building the risk and governance framework appropriate to your organisation’s size and risk profile.

Our fractional CISOs have experience across financial services, professional services, healthcare, technology, legal, manufacturing, and not-for-profit sectors. Many SMEs in regulated industries — financial services, healthcare, legal — face particularly acute security and compliance obligations. We match each engagement with a fractional CISO who understands your sector’s regulatory environment, threat landscape, and the security expectations of your enterprise customers and supply chain partners.
