How Much ISO 27001 Certification audit Costs in 2024

Embarking on the journey towards ISO 27001 certification necessitates a comprehensive understanding of the associated audit costs, which play a crucial role in ensuring a smooth and successful certification process. ISO 27001, a globally recognized standard, sets forth the best practices and stringent guidelines for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). The certification process involves a series of ISO/IEC 27001 audits, each designed to assess and validate the efficiency and efficacy of the organization’s ISMS controls and practices.

External audits, on the other hand, are pivotal in validating that the organization’s ISMS adheres to the ISO 27001 standard, ultimately leading to certification. The cost associated with these audits includes fees for the certification body, potential travel expenses, and any additional resources required to address findings and ensure compliance.

How much ISO 2700 Audit Costs in 2024?

The pricing structure for the ISO 27001 certification process can be broken down by understanding the costs associated with the audit stages. On average, the ISO 27001 certification audits for Stage 1 and Stage 2 range from $10,000 to $15,000. For small start-ups, the expenditure to hire an ISO 27001 auditor for these crucial stages typically falls between $13,000 and $15,000. It is important to note that these costs are influenced by various factors, such as the size of your organization, the number of operational offices, the intricacies of your IT infrastructure, the methods used for data storage and system management, your choice of audit partners, and the existing security measures in place.

The cost of internal and external ISO 27001 audits can vary significantly, influenced by factors such as the size and complexity of the organization, the maturity of its existing ISMS, and the specific requirements of the ISO 27001 standard. Internal audits, conducted by the organization’s own personnel or hired consultants, are a vital phase in the ISO 27001 certification process, ensuring that the ISMS is consistently aligned with the standard’s requirements. These audits help identify areas for improvement, ensuring that the organization is well-prepared for the external audit conducted by a certified body.

Understanding the cost implications of both internal and external ISO 27001 audits is essential for organizations aiming to achieve and maintain ISO 27001 certification. It ensures that they are adequately prepared, both financially and operationally, to navigate the certification process successfully and reap the long-term benefits of a robust ISMS.

What are the options to conduct ISO 27001 Audit?

Type #1: Using your Internal Team to conduct ISO 27001 Audit

When an organization chooses to take a Do-It-Yourself (DIY) approach using its internal team for ISO 27001 certification, it means leveraging existing resources to implement and manage the Information Security Management System (ISMS). This approach requires a substantial commitment from the organization’s internal team, as they will be responsible for understanding the ISO 27001 standards, developing the necessary documentation, implementing the ISMS, and preparing for the certification audit. Moreover, While the DIY approach using an internal team can be cost-effective in terms of minimizing external consultancy fees, it requires a significant investment in terms of employee time and potential lost productivity. Organizations need to weigh these internal costs against the benefits of building ISO 27001 expertise in-house and having direct control over the implementation process.


  • Internal Project Team: A cross-functional team comprising members from various departments such as IT, HR, Legal, and Operations. This team is responsible for driving the ISO 27001 implementation process.
  • Training and Awareness: The internal team needs to be trained on ISO 27001 standards and best practices. This training extends to the broader organization to ensure everyone is aware of their role in maintaining information security.
  • Documentation Development: Creating comprehensive documentation that outlines the organization’s ISMS policies, procedures, and controls. This documentation serves as the foundation for the ISMS and is critical for the certification audit.
  • ISMS Implementation: Putting the documented policies and procedures into practice across the organization. This involves a significant change management effort to ensure all employees are following the new practices.
  • Internal Audits: Conducting internal audits at planned intervals to ensure the ISMS is functioning as intended and to prepare for the external certification audit.
  • Continuous Improvement: Establishing a process for ongoing review and improvement of the ISMS to ensure it remains effective over time.

Cost Breakdown

  • Opportunity Cost of Lost Productivity: The internal team will be dedicating a significant portion of their time to ISO 27001 implementation, which could lead to lost productivity in their regular roles.
  • Training Costs: Investment in training programs and materials to ensure the internal team and the broader organization are knowledgeable about ISO 27001.
  • Employee Time: The internal team will spend several months working on ISO 27001 implementation, leading to substantial labor costs.
  • Potential Need for External Resources: Depending on the complexity of the organization’s environment and the expertise of the internal team, there may be a need to bring in external resources for specific tasks, which could incur additional costs.


The DIY approach using an internal team can be time-consuming, with the process taking 5 months or more, depending on the size and complexity of the organization.
