ISO 27001 Readiness

ISO 27001 readiness with a practical action plan.

Understand the gaps between your current security practices and the ISO 27001 requirements in your agreed scope. TISA Hub helps organise risk, control ownership, documentation and evidence so your team can work through the next actions.

Readiness support is scoped to your organisation and its existing controls.

Capabilities

Connect requirements
to controls and evidence.

For founders, CTOs and security leaders preparing an information security management system, reviewing an existing programme or responding to an assurance requirement from a customer.

01

Scope and baseline review

Identify the business activities, systems, information and dependencies included in the review. Capture existing policies, responsible people and the assurance outcome you are working towards before deciding what needs to change.

02

Readiness gap assessment

Compare applicable requirements with the controls and evidence already available. Record gaps and questions that need validation, distinguish missing documentation from missing operational practice, and prioritise the work with your team.

03

Risk register and treatment planning

Document security risks in business context, including affected systems, current controls and proposed treatment. Establish review and acceptance responsibilities so decisions remain understandable after the assessment.

04

Policies and control ownership

Develop or review policies and supporting procedures around how your organisation operates. Make control ownership, approval, review and day-to-day responsibilities explicit rather than leaving the programme dependent on a document set alone.

05

Evidence mapping and remediation

Connect applicable requirements to supporting records, system settings and operational activities. Build an evidence gap list and a remediation plan with proposed owners, dependencies and review criteria for the work in scope.

06

Internal review and handover

Support internal review planning and documentation checks within the agreed engagement. Hand over the requirements map, findings and open actions so your team can maintain the programme and coordinate with an independent certification provider.

What useful work looks like

A readiness review
your team can act on.

A useful readiness deliverable explains what was reviewed, what supports each finding and which decisions remain open. It should help leadership prioritise changes and give control owners a practical record to maintain.

Illustrative deliverable excerptSecurity assessment
Access control · example finding

Leaver access remains active.

An example account is still enabled after its owner has left. The removal process has no named review owner.

Evidence to review
Identity inventory, account status and the leaver record.
Risk context
Unnecessary access may remain available to business systems.
Proposed action
Review the account, remove unnecessary access and define a documented removal check.
Proposed owner
System owner, with People Operations supporting the leaver process.
Review before acceptanceValidate the evidence, impact and priority with the business owner.
