When it helps

Security evidence. Business consequences.

A certification, policy or completed questionnaire is a starting point. The useful question is what the evidence tells you about the risk you are taking on.

I help owners, boards, investors and advisers review security governance, resilience and dependencies before an important commercial decision. The scope is agreed around your decision, access to evidence and timeframe.

How I can help

Assurance for the decisions that matter.

01 · ACQUISITIONS

Buyer-side cyber due diligence

Review governance, incident history, critical suppliers and recovery arrangements. Identify material risks, evidence gaps and priorities for further investigation or post-acquisition improvement.

02 · SALE READINESS

Prepare for buyer scrutiny

Organise security evidence, identify gaps and prepare clear responses to diligence questions before a business sale or investment process.

03 · SUPPLIERS

Supplier and partner assurance

Assess policies, questionnaires, ISO certificates and SOC reports against your needs. Clarify dependencies, unresolved findings and decisions requiring risk acceptance.

04 · CUSTOMERS

Customer security assurance

Support security questionnaires and assurance calls with accurate, evidence-backed responses. Build a reusable evidence pack for future customer requirements.

05 · BOARDS

Independent risk review

Give executives a concise view of security maturity, ownership, resilience and improvement priorities, with findings expressed in business terms.

06 · FOLLOW-THROUGH

From findings to action

Turn the assessment into an accountable improvement plan. Add fractional CISO support where continuing leadership is needed.

The outcome

A clear view of what is known, what remains uncertain and what needs to happen next.

Questions before we start

A focused scope. Proportionate assurance.

Does every review need technical testing?

No. Interviews and evidence review can establish governance, assurance and resilience gaps. Where a decision needs penetration testing, forensic investigation or specialist architecture analysis, I help define that additional scope and coordinate the relevant specialists.

Can you work with our existing advisers?

Yes. I can work alongside corporate finance advisers, legal teams, fractional CFOs, IT providers and internal teams, with clear responsibilities and reporting.

Can you help before we sell or raise investment?

Yes. Readiness work can organise your evidence and address gaps before buyer or investor questions arrive. Findings reflect the scope and evidence available; they do not guarantee an incident-free business or a transaction outcome.

Is ongoing support available?

Start with a defined project, then add fractional CISO leadership to oversee improvements where needed.
