Getting ISO 27001 certification—which demonstrates that your organization has a robust Information Security Management System (ISMS)—involves several key steps.
What is ISO/IEC 27001?
ISO/IEC 27001 is an international standard for managing information security. It helps organizations secure confidentiality, integrity, and availability of data by applying risk management processes.
How to Get ISO 27001 Certification: Step-by-Step
1. Understand the Standard
Read and understand ISO/IEC 27001:2022 (or the latest version).
You can buy the official standard from iso.org.
2. Get Leadership Commitment
Ensure top management supports the initiative—it’s a requirement in the standard and crucial for success.
3. Define the Scope of the ISMS
Decide what parts of your organization the ISMS will cover (e.g., a specific department, your entire company, etc.).
4. Conduct a Risk Assessment
Identify potential risks to information security.
Evaluate likelihood and impact.
Decide how to treat those risks (accept, avoid, reduce, or transfer them).
5. Implement Controls (Annex A)
ISO 27001 includes 93 controls in Annex A (new in the 2022 version).
Apply relevant controls from Annex A to address identified risks.
6. Develop Policies & Procedures
Create and document key ISMS elements, such as:
Information Security Policy
Access Control Policy
Incident Response Plan
Business Continuity Plan
7. Training & Awareness
Train your team on their roles in information security.
Promote a culture of security awareness.
8. Internal Audit
Conduct an internal audit to ensure your ISMS meets ISO 27001 requirements.
Fix any non-conformities.
9. Management Review
Top management must review audit findings and ISMS performance.
10. Select a Certification Body
Choose an accredited certification body (like BSI, TÜV, DNV, or SGS) to perform your external audit.
11. Stage 1 Audit (Documentation Review)
The auditor will review your documentation to verify readiness.
12. Stage 2 Audit (On-site or Remote Audit)
A deeper audit of how your ISMS is implemented and operating.
If successful, you’ll be granted certification (valid for 3 years).
13. Maintain and Improve the ISMS
Conduct annual surveillance audits to stay certified.
Continually monitor, review, and improve your ISMS.
