An organisation can have an information security management system (ISMS) certified or receive a label for it. The leading international standard for organizations to have their ISMS certified is ISO/IEC 27001. TISAX is an assessment and exchange mechanism for information security and is particularly important in the German automotive industry. In order to receive a certificate or label for your ISMS, you must pass a certification audit by an accredited certification body.
