ISO 27001 case study
ISO 27001 in four weeks for a healthcare company
A large new project required ISO 27001 certification before a fixed start date.
The challenge
A large new project required ISO 27001 certification before a fixed start date. The client already had many good security practices but no information security management system, and a typical six-month programme would have cost them the contract.
What we did
- Booked the Stage 1 and Stage 2 audit dates with an accredited certification body before day one.
- Kept the scope tight to the services the new project needed, with a plan to extend it later.
- Ran the gap assessment against clauses 4 to 10 and Annex A, the risk assessment with leadership and the Statement of Applicability in the first week.
- Tailored our policy library to how the client actually works, while the client's team closed gaps in access reviews, asset inventory, supplier reviews, logging and awareness training.
- Generated real operating records, then ran the internal audit and management review before Stage 1.
Timeline
- Week 1: scope, gap assessment, risk assessment, Statement of Applicability
- Week 2: policies tailored, control gaps closed by the client's team
- Week 3: operating records, internal audit, management review, Stage 1 audit
- Week 4: Stage 1 observations closed, Stage 2 audit
Results
- Stage 2 completed with a recommendation for certification.
- No nonconformities. Two minor observations were raised, and both were already on the client's improvement roadmap for the next year.
- The client met its project start date.
What made it work
A firm deadline with executive backing, a client team assigned full-time for four weeks, existing controls that only needed formalising, and audit dates secured first. Four weeks is the exception: most organisations should plan three to six months.
