How long does it take to get ISO 27001 certified?

by Sneha Naskar

The time it takes to achieve ISO 27001 certification can vary significantly depending on several factors, including the size and complexity of your organization, your existing information security practices, and the resources allocated to the certification process. On average, it typically takes organizations between 6 to 12 months to become ISO 27001 certified. However, it's essential to understand the key stages and considerations that contribute to this timeline.

  • Initial Assessment (1-2 months): The first step is to conduct an initial assessment of your organization's current information security practices and identify the gaps that need to be addressed to meet ISO 27001 requirements. This stage involves understanding the scope of certification, defining objectives, and assembling a project team.
  • Gap Analysis (2-3 months): After identifying the gaps, you'll need to develop a comprehensive plan to bridge them. This may involve creating or updating policies, procedures, and security controls to align with ISO 27001 standards. The duration of this phase depends on the extent of existing practices and the complexity of your organization.
  • Implementation (3-6 months): During this phase, you'll execute the plan developed in the gap analysis stage. This includes implementing new security controls, training employees, and making necessary changes to your organization's processes. Larger organizations or those with complex infrastructures may take longer to complete this phase.
  • Internal Audit (1-2 months): Before pursuing external certification, an internal audit is conducted to assess the effectiveness of the implemented controls and ensure they meet ISO 27001 requirements. Any identified issues must be addressed and resolved.
  • Management Review (1-2 months): Senior management must review the results of the internal audit and ensure that the information security management system (ISMS) is operating effectively. Necessary adjustments and improvements should be made based on this review.
  • External Audit (2-3 months): After successfully completing the internal audit and management review, an accredited certification body (CB) will conduct an external audit. This process involves assessing whether your ISMS complies with ISO 27001 standards. The duration may vary based on CB availability and scheduling.
  • Certification (1-2 months): Once the external audit is completed and any identified issues are resolved, the CB will issue ISO 27001 certification if your ISMS meets the standards. You'll receive a certificate valid for three years, subject to annual surveillance audits.

It's important to note that the timeline provided here is a general estimate, and the actual duration can vary widely. Smaller organizations with simpler information security setups may complete the process more quickly, while larger, more complex organizations may require more time. Effective project management, resource allocation, and commitment from top management are crucial factors that influence the timeline for ISO 27001 certification.

Additionally, achieving and maintaining ISO 27001 certification is an ongoing process that requires continuous improvement and monitoring of your ISMS. Organizations should allocate resources to sustain compliance and adapt to changing security threats and business needs.
