How to Structure Your ISO 27001 Certification Project in 6 Months

Key steps, pitfalls to avoid and resources needed for a successful ISO 27001 certification — a concrete project plan for Canadian organizations.

8 min readJanuary 2025

ISO 27001 certification is a structuring project that requires rigor, management commitment and dedicated resources. Six months is an ambitious but achievable timeline for organizations that start with an existing documentation base. Here is a proven project plan.

6-month project plan

Month 1

Scoping and management commitment

  • Obtain formal management mandate (sine qua non)
  • Define the ISMS scope (systems, processes, sites covered)
  • Assemble the project team (CISO, DPO, business representatives)
  • Choose the certification body (BSI, Bureau Veritas, SGS, etc.)
  • Conduct an initial gap analysis to assess maturity level

An overly broad or poorly defined scope is the leading cause of failure.

Month 2

Risk analysis and treatment plan

  • Choose and document the risk assessment methodology
  • Complete the information asset inventory
  • Identify threats, vulnerabilities and impacts
  • Assess and prioritize risks according to defined appetite
  • Draft the Statement of Applicability (SoA)

The SoA is the central document of the audit — do not neglect it.

Months 3-4

Controls implementation

  • Implement priority controls from Annex A
  • Draft or update security policies
  • Train staff on policies and procedures
  • Implement security incident management
  • Document key operational procedures

Prioritize high-impact controls — implementing everything in 6 months is unrealistic.

Month 5

Internal audit and management review

  • Conduct a full ISMS internal audit
  • Document non-conformities and open corrective action plans
  • Hold the formal management review with results
  • Validate that all required records are in place
  • Conduct an incident or business continuity simulation exercise

The internal audit must be conducted by someone independent of the audited process.

Month 6

Certification audit (Stage 1 + Stage 2)

  • Document review (Stage 1): verification of policies and SoA
  • Correct minor gaps identified during Stage 1
  • On-site audit (Stage 2): verification of effective implementation
  • Address any non-conformities within the allotted time
  • Obtain the certificate (valid 3 years, annual surveillance audits)

Between Stage 1 and Stage 2, allow 2 to 4 weeks for corrections.

The 5 most common pitfalls

1

Treating ISO 27001 as an IT project only

Certification concerns the entire organization, not just IT. Management and business units must be involved.

2

Underestimating the documentation workload

ISO 27001 requires substantial documentation: policies, procedures, records, audit results. Plan the necessary human resources.

3

Copy-pasting generic policies

Policies must reflect your organization's reality. An experienced auditor immediately detects unapplied policies.

4

Neglecting staff training

Annex A requires staff to be security aware. Without documented training, non-conformities are inevitable.

5

Forgetting surveillance audits

Certification lasts 3 years with annual surveillance audits. The ISMS must be continuously maintained and improved.
