SSI-approved Assessment Bodies are responsible for conducting independent, third-party audits, to certify member sites against the SSI Standards. The SSI accepts assessment bodies (ABs), and individual assessors associated with approved ABs, based on the requirements defined in the SSI core document: ‘Assessment Body and Assessor Approval Procedure’.

To be eligible to conduct assessments as an SSI-approved Assessment Body, please refer to the criteria set out in the ‘Assessment Body and Assessor Approval Procedure’. This procedure ensures audit companies and their individual assessors follow best auditing practices, are independent, and have the required technical knowledge to evaluate requirements in the SSI Standards.
