ISA 2.1 Major version
The catalogue version TISAX started with in 2016, then heavily based on ISO/IEC 27001. source
Who it applies to
Companies in the automotive supply chain that handle partners' sensitive information, when a partner requires a TISAX label.
- Who takes part
- Companies use the ISA internally and for assessments of suppliers and service providers that are part of the automotive supply chain. source
- What it protects
- Design data, production information, customer information, prototypes and intellectual property. source
- Why it is required
- Some participants made it a mandatory requirement for many of their suppliers to prove that their ISMS meets a defined set of requirements. source
- Which label
- The partner names the TISAX label it requires, and the supplier selects the matching assessment objective. source
- Contracts
- A participant usually signs two contracts: the TISAX Participant General Terms and Conditions with ENX Association, and a contract with an audit provider. source
- Catalogue in use
- ISA 6 is the current version, effective for TISAX assessments ordered from 1 April 2024. Assessments ordered in 2027 use ISA2027; the final date to open an initial assessment under ISA 6 is March 2027. source source
- Next catalogue
- ISA2027 strengthens supplier and supply chain requirements: for very high protection needs, suppliers must show a TISAX label, an equivalent third-party assessment or a supplier audit. Prototype protection was consolidated from five control groups into two domains, with new requirements on traceability and on disposal or return of protected parts. Mappings were updated to NIST CSF 2.0, ISO/IEC 27001:2022 and ISA/IEC 62443, and references to ISO/IEC 27001:2013 were removed. source
How compliance is assessed
A self-assessment against the ISA, then an assessment by an ENX-approved audit provider. The resulting TISAX labels are valid for up to three years.
- Process
- Registration of the participant and its assessment scope, choice of an audit provider, the assessment, then exchange of the results with partners. source
- Assessment
- Starts with a self-assessment based on the ISA, followed by an external audit that ranges from document reviews to on-site inspections depending on protection needs. source
- Audit providers
- ENX Association approves audit providers and monitors the quality of implementation and the assessment results. source
- Assessment levels
- Higher assessment levels include lower ones: an assessment at level 3 fulfils all requests for level 2. source
- Validity
- TISAX labels are valid for at most three years, counted from the closing meeting of the initial assessment. source
- Annual ISA releases
- The annual catalogue cycle does not change label validity or increase reassessment frequency. source
- Result format
- Results are shared through the ENX Portal with chosen partners and are not public; ENX issues no wall certificate. source source
Enforcement and penalties
Enforced through business relationships: partners demand labels, and a participant that does not fix non-conformities in time gets none.
- Partner demand
- Partners set TISAX labels as a requirement for their suppliers and name the label they need. source source
- Non-conformities
- Non-conformities must be resolved within nine months of the initial assessment's closing meeting; otherwise no TISAX labels are issued, and the participant can start a new initial assessment. source
