Annex A requirements, which are divided between years one and two after your certification audit (your auditor will determine how the requirements are split).

Surveillance auditsĪfter achieving certification, you must schedule surveillance audits with a certification body. This is the only type of ISO 27001 audit that is conducted only once, when you are first awarded your certificate of compliance. During those three years, you’re obligated to maintain your ISMS and the processes, ISO 27001 controls, and requirements that helped you achieve compliance. The certification audit is conducted by a certification body, and if you prove compliance, you will receive a certificate of compliance that’s valid for three years. Let’s take a look at all three types of external ISO 27001 audits below. However, the term also refers to other types of audits conducted by certification bodies. The term “external audit” most commonly refers to the certification audit, in which an external auditor will evaluate your ISMS to verify that it meets ISO 27001 requirements and issue your certification. These audits are called a “second-party audit.” External auditsĮxternal audits are carried out by a certification body to determine whether your organization satisfies ISO 27001 requirements on an ongoing basis. If a business doesn’t have an internal auditor they can use an outside party. These audits can be carried out by an organization’s own internal audit team. They must be conducted on a regular basis and must document the audit process. These audits are meant to review and assess the effectiveness of the company’s ISMS. ISO 27001 requires organizations to plan and conduct internal audits in order to prove compliance. Find out what they are, who they’re conducted by, and how often they occur. Below is an overview of the different types of ISO 27001 audits.
