What is TISAX?

More context

TISAX exists to solve a supply-chain problem specific to carmakers: an OEM shares sensitive design and prototype data with hundreds of suppliers, and it cannot practically audit each one itself. Instead the industry agreed on a shared assessment that a supplier undergoes once and can then present to any participant, so a single credible result substitutes for many redundant customer audits across the network.

Because its control catalog is built on ISO 27001's Annex A, much of what TISAX asks for at the technical level overlaps with the same secure-configuration expectations that other information-security frameworks impose. A supplier that already maintains hardened, continuously evidenced systems is therefore addressing a substantial part of the technical scope, leaving the assessment to concentrate on process maturity and the automotive-specific handling requirements layered on top.
