TISAX® is a cross-organisational assessment and exchange procedure for information security in the automotive industry. It focuses on the protection of data, its integrity and availability throughout the manufacturing process and during the operation of vehicles.
This is achieved through an Information Security Management System (ISMS) analogous to the ISO 27001 standard. Based on this standard, the VDA has developed the specific ISA requirements and assessment catalogue for the automotive sector.
The effectiveness of an ISMS can be demonstrated through assessments against the VDA-ISA. Upon successful testing, e.g. by TÜV NORD, ENX* – the administrator of the TISAX® programme – issues a TISAX® label in its database. This is recognised and required by all VDA members and vehicle manufacturers such as Audi, Volkswagen and BMW.
Participants in the TISAX® process exchange information on the status of information security via a shared online portal. Registration on the portal is mandatory for participation in a TISAX® process. In addition to the exchange of assessment data, the portal also enables participants to contact audit service providers. Within the exchange model, there are two roles that each company can assume as required.
Passive participants include, for example, vehicle manufacturers. These require another company (e.g. their supplier) to provide evidence of specific TISAX® labels, thereby carrying out an assessment against the appropriate audit objectives, and request access to the audit results.
Active participants or auditees include, for example, suppliers: a company is either requested by another company (e.g. an OEM or car manufacturer) to undergo an audit against the criteria catalogue, or it undergoes an audit on its own initiative. Once the audit has been completed, the active participant decides who within the TISAX® network is granted access to its audit results.
Participants in the TISAX® process exchange information on the status of information security with one another via a shared online portal. Registration on the portal is mandatory for participation in a TISAX® process. In addition to the exchange of assessment data, the portal also enables participants to contact audit service providers. Within the exchange model, there are two roles that each company can assume as required.
The TISAX® process essentially consists of three phases: registration, assessment and exchange. Would you like to find out in detail how you can navigate these three phases? Our guide, ‘How do TISAX® assessments work?’, will help you understand the entire process.
The ENX Association, as the operator of the TISAX® programme, has clearly defined the levels and scope of the assessments. TISAX® distinguishes between three different protection classes and assessment levels against which an organisation can be assessed. These assessment objectives depend on the level of protection required for the information.
This is intended for standard security requirements. The auditee can carry out the assessment as a self-assessment.
Assessment Level 2 is aimed at suppliers and service providers with high security requirements. A prerequisite for this is the submission of a complete self-assessment. The audit provider then carries out the following steps:
Level 3 assessment involves very high security requirements. An audit provider (TISAX® AP) must also be involved here, and a complete self-assessment must be submitted. The subsequent audit steps are similar to those for Level 2 assessment, except that key aspects are examined during an on-site audit.
Following the assessments, the results and the requirements for corrective actions are summarised in a preliminary report. In this case, two further audit steps are required to obtain a TISAX® label:
TISAX® stands for Trusted Information Security Assessment Exchange and describes an assessment and exchange process for information security in the automotive industry.
Only audit service providers approved by ENX for this purpose (TISAX® AP) are permitted to carry out TISAX® assessments. TÜV NORD CERT is ENX’s contractual partner for this purpose.
Developed by the German Association of the Automotive Industry (VDA), TISAX® is managed by the ENX Association, which monitors the quality of the assessments and their results.
The scope and duration of the TISAX® audit are primarily determined by the agreed audit objectives, the maturity and complexity of the ISMS, and the number of sites to be audited.
A fixed period of nine months is available from the closing meeting (concluding meeting of the initial assessment) until the completion of the entire assessment process (including verification of the successful implementation of any necessary corrective measures). If this deadline cannot be met, the process must be restarted from the beginning. After three years (the validity period of the TISAX® label), the process must be repeated.
All suppliers and service providers to car manufacturers and their suppliers who process sensitive information belonging to those organisations should have an interest in participating in TISAX®. On the one hand, this enables them to meet their customers’ requirements. On the other hand, it means they avoid having to undergo the same audits repeatedly at the hands of their customers. This is because clients regularly require their suppliers to provide evidence that they meet information security requirements.
To receive a quote for a TISAX® audit, interested parties must first register on the ENX portal and provide the relevant information. Please contact us if you would like us to assist you with the quote request process.
Companies can gain access to the TISAX® portal, which facilitates the exchange of assessment data, by registering as a participant. This is a prerequisite for commissioning an assessment from an assessment provider (TISAX® AP) such as TÜV NORD.
ENX has compiled detailed information on TISAX® in a participant handbook available on its website.
