Can you obtain a certificate of compliance with ISO/IEC 27017?

Yes, it is possible to obtain a certificate of compliance with the ISO/IEC 27017 standard. Certification is a process in which an independent, accredited certification body conducts an audit of an organization’s information security management system (ISMS) for compliance with the requirements of the ISO/IEC 27017 standard. Obtaining a certificate confirms that the organization’s ISMS is compliant with the standard’s requirements and is effectively implemented.

Certification of compliance with ISO/IEC 27017 is particularly important for cloud service providers who want to demonstrate to their customers and other stakeholders that they apply best practices in information security. The certificate is recognized worldwide and constitutes credible confirmation that the provider meets international security standards.

The certification process for compliance with ISO/IEC 27017 includes the following steps:

Implementation of ISMS compliant with standard requirements: The organization must establish, implement, maintain and continuously improve an ISMS that meets the requirements of ISO/IEC 27017. This includes developing policies, procedures, control mechanisms and documentation in accordance with the standard’s guidelines.
Selection of accredited certification body: The organization selects an independent certification body that is accredited to conduct compliance audits with ISO/IEC 27017. Accreditation is confirmation that the body has appropriate competence, independence and recognition. The choice of body may be based on factors such as experience, reputation, scope of accreditation or service costs.
Documentation review and preliminary audit (optional): Before the actual certification audit, the organization may decide to have its ISMS documentation reviewed by the certification body. This review allows for preliminary assessment of documentation compliance with standard requirements and identification of any gaps. The organization may also use an optional preliminary audit, which simulates the course of the certification audit and helps identify areas requiring improvement.
Certification audit: The key stage of the certification process is the certification audit conducted by the certification body. The audit includes review of documentation, interviews with personnel, observations and tests to verify that the ISMS is compliant with ISO/IEC 27017 requirements and is effectively implemented. Auditors assess, among others, policies, procedures, control mechanisms, risk management, monitoring and continuous improvement of the ISMS. The audit can be conducted on-site or remotely, depending on agreements between the organization and the certification body.
Audit report and corrective actions: After completion of the certification audit, the certification body prepares a report that contains the audit results, including any non-conformities or areas requiring improvement. Non-conformities are classified as minor or major, depending on their impact on ISMS effectiveness. The organization has the opportunity to implement corrective actions to eliminate non-conformities before the certificate is issued. These actions must be documented and verified by the certification body.
Certificate issuance: If the audit results are positive and all non-conformities have been eliminated, the certification body issues a certificate of compliance with ISO/IEC 27017. The certificate is typically valid for three years, subject to conducting annual surveillance audits to verify continued compliance.
Surveillance audits and recertification: During the certificate’s validity period, the certification body conducts annual surveillance audits to ensure that the organization’s ISMS still meets ISO/IEC 27017 requirements and is effectively maintained. After three years, the organization must undergo the recertification process to renew the certificate for another three years.

Obtaining a certificate of compliance with ISO/IEC 27017 brings organizations many benefits:

Increases customer and other stakeholder trust, demonstrating commitment to information security.
Confirms that the organization’s ISMS meets international standards and good practices.
