A sample answer to question 1

How would you carry out a cyber security maturity assessment for a client, and which frameworks would you use?

I'd start by agreeing scope, objectives and the client's context, because a regional charity and a financial services firm need different benchmarks. I'd choose a framework that suits them: NIST Cybersecurity Framework 2.0 for a broad view, the NCSC Cyber Assessment Framework for critical services, ISO 27001 for certification goals, or CIS Controls for technical hardening. I'd run structured interviews with IT, security, HR, legal and the business, review policies, architecture diagrams and previous audit and test reports, and sample technical evidence, such as configuration exports, to validate what people say. I'd score each domain on a consistent maturity scale and highlight where current state differs from target state. The output would be a short executive summary, a heat map, and a prioritised, costed roadmap with quick wins separated from longer-term investments. I'd workshop findings with the client before the final report so recommendations are realistic and owned.

Common mistake to avoid: One-size-fits-all checklist; Report without workshop
