How Long Does It Take To Get ISO 27001 Certified

by Alex .

In an era where information security is paramount, achieving ISO 27001 certification stands as a testament to an organization's commitment to safeguarding its digital assets. The process of obtaining this prestigious certification entails a meticulously orchestrated series of steps, each contributing to the fortification of an organization's information security management system (ISMS). Discover the intricate timeline and multifaceted process involved in acquiring ISO 27001 certification, encompassing every stage from inception to accomplishment.

ISO 27001

1. Pre-Assessment Phase (Duration: 2-4 Weeks)

The voyage towards ISO 27001 certification commences with a preliminary assessment. Here, the organization's current information security practices undergo scrutiny, and the foundation for subsequent steps is laid. The duration of this phase hinges upon the organization's preparedness and the extent of modifications required. On average, this preliminary assessment might span between 2 to 4 weeks, setting the groundwork for the journey ahead.

2. Gap Analysis (Duration: Weeks to Months)

Once the initial assessment is concluded, an intricate gap analysis ensues. This entails a meticulous comparison between the organization's existing security measures and the exhaustive requirements stipulated by the ISO 27001 standard. The temporal span of this phase varies immensely, ranging from a few weeks for smaller entities to several months for complex and expansive organizations.

3. Risk Assessment and Management (Duration: Weeks to Months)

Central to ISO 27001 implementation is the identification, assessment, and management of information security risks. A comprehensive risk management framework is established, scrutinizing vulnerabilities, appraising potential consequences, and devising risk mitigation strategies. The dynamic and iterative nature of this process can encompass weeks or even months, dictated by the intricacies of the organization's structure and operations.

4. Development of Information Security Management System (ISMS) (Duration: 3-6 Months)

The nucleus of ISO 27001 implementation resides within the creation of the ISMS. This intricate framework comprises policies, procedures, processes, and guidelines that holistically manage information security risks. The development of this multifaceted system requires meticulous detailing of security controls, crafting risk treatment blueprints, and delineating roles and responsibilities. This pivotal phase unfolds over a span of 3 to 6 months, contingent upon the organization's magnitude and intricacy.

5. Implementation and Testing (Duration: 3-6 Months)

With the ISMS framework in place, the organization embarks on the execution and validation of identified security controls. This endeavor entails employee training, awareness campaigns, and seamless integration of security practices into daily operations. Rigorous testing of the implemented controls via simulations and assessments verifies their efficacy. This phase extends across 3 to 6 months, adapting to the scale of implementation and the extent of testing requisites.

6. Internal Audit (Duration: 1-2 Months)

Before embarking on the quest for external certification, an internal audit of the ISMS is conducted. Independent internal auditors meticulously review the ISMS to ensure its congruence with ISO 27001 requirements. This internal audit provides a preliminary check for any gaps or discrepancies necessitating rectification before the external audit. The internal audit phase typically spans 1 to 2 months.

7. External Audit (Certification Audit) (Duration: Days to Weeks)

A pivotal juncture in the certification expedition involves the external audit, executed by an accredited certification body. Expert auditors meticulously assess the organization's ISMS, scrutinizing its alignment with the rigorous ISO 27001 standards. This audit is typically executed in two stages: an exhaustive document review followed by an on-site assessment. The temporal scope of the external audit spans days to weeks, contingent upon the organization's complexity and operational expanse.

8. Corrective Actions and Certification (Duration: Weeks to Months)

Following the external audit, any identified non-conformities or findings necessitate rectification. Once these amendments are successfully executed, the certification body bestows the coveted ISO 27001 certification. The temporal span for addressing corrective actions and obtaining certification fluctuates between a few weeks to several months.

How to speed up the certification process

Speeding up ISO 27001 certification involves strategic steps. Obtain leadership support for swift decision-making and resource allocation. Establish a dedicated team, defining clear ISMS scope to stay on track. Leverage existing resources and prioritize high-impact risks for effective risk mitigation. Implement automation tools and ISO 27001 templates to streamline processes. Run parallel tasks, conduct internal audits, and ensure employee engagement.

Seek external expertise and readiness checks before the final audit. Embrace continuous improvement to maintain effectiveness post-certification. Balancing efficiency with quality ensures a swift, successful ISO 27001 certification process, fortifying information security and operational resilience.

Navigating Potential Roadblocks on the Path to ISO 27001 Certification

Embarking on the ISO 27001 certification journey can encounter obstacles that extend the timeline. Insufficient resources, both human and financial, may impede progress, causing delays in tasks. A lack of senior management buy-in can hinder decision-making and resource allocation, slowing down implementation efforts. Scope ambiguity might lead to confusion and expanded workloads, stretching the timeline.

Resistance to change from employees, combined with inadequate training, could undermine the effectiveness of new security measures, causing setbacks. Technical complexities, especially in intricate IT environments, might necessitate extra time for risk assessments and control implementations. Regulatory or legal challenges, unforeseen third-party dependencies, and cultural resistance can also contribute to delays. Addressing these potential roadblocks proactively is crucial for ensuring a streamlined and efficient path to ISO 27001 certification.


The odyssey toward ISO 27001 certification is an intricate expedition that underscores an organization's dedication to fortifying information security. This comprehensive timeline weaves through multifarious phases, each contributing to the creation of a robust information security management system. While the overarching process spans approximately 9 to 18 months on average, it is crucial to note that individual circumstances can precipitate variations in this timeline. By diligently adhering to the ISO 27001 implementation framework, organizations can galvanize their information security posture and flourish within the evolving digital landscape.
