Security strategy and governance
Assess the current position, clarify appetite for risk and shape a proportionate roadmap that leadership can sponsor and delivery teams can use.
CYBER SECURITY LEADERSHIP
Fractional & Interim CISO.
Clarity when it matters.
You may need CISO-level judgement without a permanent appointment, or experienced leadership during a transition. I help organisations understand their cyber exposure, establish clear priorities and give accountable direction to the teams delivering change.

THE BUSINESS CASE
What a fractional CISO can actually change
A fractional CISO is not simply an occasional security review. The value comes from having a senior adviser who can question assumptions, support leadership decisions and maintain a coherent direction across people, technology and suppliers.
The scope should match the organisation's needs. It may be a defined period of interim leadership, a regular advisory commitment or a time-bound security transformation programme. The aim is practical oversight, not creating unnecessary process.
HOW I HELP
Where I can help
Board and executive reporting
Translate vulnerabilities, incidents, third-party dependencies and control weaknesses into clear exposure, decisions and priorities.
Remediation and transformation oversight
Help teams establish owners, realistic sequencing and evidence of progress across control improvement and security programmes.
Supplier, incident and resilience readiness
Challenge whether response plans, recovery assumptions, external providers and assurance activities are workable rather than merely documented.
PRACTICAL APPLICATION
When it makes sense to bring in an interim or fractional CISO
- Leadership needs an independent view of security risk before approving investment.
- A permanent security leadership role is vacant or not yet justified.
- An acquisition, separation or major change has increased security demands.
- Security findings are accumulating but ownership and delivery priorities are unclear.
- Existing teams need senior sponsorship and an interface with the board.
INDEPENDENT PERSPECTIVE
Experience grounded in delivery
My background spans IT leadership, specialist cyber security consultancy and oversight of assessment and remediation work. I have founded and led a specialist cyber security firm, and supported security risk and transformation activity in complex industrial and manufacturing environments.
That combination matters: effective CISO leadership requires enough technical depth to challenge evidence, but also the ability to make risks understandable, negotiate priorities and maintain accountability.

ENGAGEMENT OUTPUTS
What would the organisation receive?
The first step is agreeing the leadership gap and the decisions that need support. Depending on scope, an engagement may include:
- An independent view of material cyber risks, evidence gaps and immediate priorities.
- A proportionate security roadmap with accountable owners and clear decisions for leadership.
- A regular executive reporting approach that focuses on risk, investment choices and progress.
- Oversight of remediation, supplier dependencies and a practical handover where the role is interim.
These are examples of possible outputs, not a fixed package. Responsibilities, availability, reporting and deliverables are agreed for each engagement.
COMMON QUESTIONS
Choosing the right leadership arrangement
What's the difference between fractional and interim CISO support?
Fractional support usually provides ongoing leadership on an agreed part-time basis. Interim support typically fills a defined leadership gap or carries responsibility through a period of transition. The level of involvement should reflect the organisation's risks and available internal capability.
Does this replace the existing IT or security team?
Not usually. The role is to provide direction, executive challenge and accountable oversight, while working with the people who operate the systems and implement improvements.
How do we decide the scope?
We start with the business decision, leadership gap or change programme that needs support, then agree the expected outcomes, stakeholders and an appropriate level of involvement.
