Trusted Information Security Assessment Exchange (TISAX)

The Trusted Information Security Assessment Exchange (TISAX) is a standardized protocol for conducting security assessments within the automotive industry. It is a mechanism established to ensure a uniform level of information security, data protection, and compliance among all participants, including manufacturers and service providers within the automotive supply chain. TISAX enables companies to undergo an independent assessment, which other participating organizations can accept without the need for redundant audits.

TISAX Certification

Gaining TISAX certification demonstrates that a company meets specific high standards of information security tailored to the sensitive nature of the automotive industry. The certification process involves a detailed examination of a company’s information security management systems (ISMS) to ensure they align with the stringent requirements specified under TISAX. Once certified, a company’s compliance status is recognized by all other participating automotive industry entities, facilitating smoother collaboration and partnerships.

TISAX Compliance

Compliance with TISAX is mandatory for any company seeking to engage with certain automotive manufacturers, particularly in Germany where the standard originated. TISAX compliance implies that the company adheres to the high standards of security protocols and data handling practices as laid out by the ENX Association—the governing body responsible for TISAX. Compliance helps companies safeguard against information theft, data breaches, and other cyber threats, thereby fostering a secure business environment.


A TISAX audit is a comprehensive evaluation conducted by accredited and independent auditors. These audits are designed to verify that the information security measures a company has in place are effective and meet the TISAX requirements. The audit process typically involves reviewing technical and organizational security measures, data protection protocols, and compliance with legal requirements. The outcomes of a TISAX audit are crucial as they determine a company’s qualification to receive TISAX certification.

TISAX Assessment

The assessment process under TISAX includes an initial self-assessment followed by an external audit conducted by a TISAX-accredited service provider. This rigorous assessment ensures that all aspects of a company’s ISMS comply with the specific requirements set out by TISAX. The assessments are categorized into different levels based on the sensitivity of the information handled, with each level requiring a deeper and more stringent evaluation. The results of these assessments are shared within the TISAX network and are valid for three years.

TISAX Requirements

To meet TISAX requirements, a company must implement several key security controls and processes. These include establishing an effective ISMS, regular training for employees on security policies, implementation of physical and technical measures to protect sensitive data, and regular audits and assessments to ensure continuous compliance. The requirements are heavily based on the European General Data Protection Regulation (GDPR) and tailored to the specific needs of the automotive industry.


TISAX stands as a crucial standard within the automotive sector, promoting high levels of trust and security in inter-company exchanges. By adhering to TISAX standards, companies not only enhance their security posture but also gain a competitive advantage in an industry where security and data protection are paramount. The collaborative nature of TISAX helps reduce the administrative and financial burden associated with multiple security assessments, thereby streamlining operations and enhancing efficiency across the automotive supply chain.
