The certification process varies by company and is not “a one-size-fits-all” checklist. Several factors will determine the timeline of how long it takes you to achieve ISO 27001 Certification.

Size/complexity: A small startup company with 10 employees utilizing cloud-based solutions will progress toward ISO 27001 Certification at a faster pace than a medium-sized company with hundreds of employees or larger companies with more intricate business environments that utilize many different types of physical security methods.

Current maturity level of security: If your company has already created and implemented documented information security policies and practices, has established strict access control mechanisms and the resources to implement ISO 27001 Certification within 12 months, then your organisation will be well-positioned to achieve ISO 27001 certification efficiently.

If your company has none of these, then preparing for ISO 27001 will take 1-3 months depending on the capabilities and finances of the organization.

Dedication and Resources: In general, the companies that dedicate a team internally or utilize a consultant for ISO 27001 Certification, often complete certification more efficiently compared to organisations managing the process without external support.

The Timeline for ISO 27001 Implementation

Understanding the timeline for ISO 27001 certification is much easier when you break it down into 5 Phases:

Phase 1 – Preparation and Gap Analysis (Weeks 1-4): This is when you (or your consultant) will compare your current state against the applicable Annex A controls of the ISO 27001 standard to assess what is missing from your operations and develop a roadmap of activities for the next few months.

Phase 2 – Risk Assessment and Treatment (Weeks 5-10): When conducting this phase, you will identify all potential sources of risk to your data; the potential for cyber-attack, possible theft of your data via physical means, employee error, etc.

Phase 3 – Documentation and Controls (Months 3-5):You need to create your “Statement of Applicability” (SoA) and document the various policies that you’ve created.

The internal training phase and the implementation of systems (Phase 4: Internal Training and “Live” with the System) takes approximately five to seven months, while the Two-Stage Audit phase (Phase 5: Two-Stage Audit) will usually occur within eight to twelve months.

The first audit, or Stage 1: Readiness Review, checks for documentation of compliance with the ISO27001 standard

The second audit, or Stage 2: Effectiveness Audit, will involve either an onsite visit to observe the system or a thorough remote audit
