Version 5.1.0 of the VDA ISA Catalog is available!

What is the VDA ISA Catalog anyway?
The VDA ISA Catalog describes the information security requirements of the automotive industry. It contains industry-wide coordinated requirements for information security and is the basis for assessments to determine the level of information security (Information Security Assessments - ISA for short). The VDA ISA catalog is the basis for the TISAX® assessment.


And TISAX® was again...?
The VDA ISA calls for the protection of information and data within the company.

TISAX® is an industry standard for the automotive industry that pursues various test objectives such as information security, prototype protection and data protection.

Those requirements of the VDA ISA for information security in the automotive industry can be proven by the company in question if the audit is successful.


The requirements originate from the automotive sector, but they are aimed at ALL institutions that exist in the automotive value chain. This includes companies that immediately come to mind, such as manufacturers of automotive parts.

But they also include those companies that you might not immediately think of, such as trade show builders, media agencies, or printers that work for or are contracted by automotive groups.


What's new in the VDA ISA catalog version 5.1?
In 2020, the VDA ISA Catalog Version 5.0 was fundamentally revised and optimized - below we have reported in detail on all the changes and the impact on a TISAX® assessment.

According to the change history in the VDA ISA Catalog 5.1, the following changes and adjustments have now been added:

  • Correction of spelling and expression, linguistic clarification, elimination of ambiguities.
  • Restructuring of spreadsheet "Welcome", definition of spreadsheets moved to "Definition".
  • Addition of protection goals regarding requirements for high and very high protection needs in the "Information Security" spreadsheet
  • Removal of the "Addressed protection goals" column in the "Information security" and "Prototype protection" spreadsheets
  • Contents of the "Usual process owner" column in the "Information security" and "Prototype protection" spreadsheets emptied out

Thus, with version 5.1, in addition to language corrections, the protection goals regarding requirements for high and very high protection needs were added to the "Information Security" spreadsheet. No change in requirements took place.

In establishing and maintaining an appropriate level of information security, member companies are supported by the "Information Security Recommendation" and the VDA ISA catalog.

From 01 October 2020, the VDA ISA Catalogue, Version 5.0 will be used for new TISAX® assessments.

Until then, the previous VDA ISA catalogue, version 4.1.1, applies.

And don't panic: For ongoing TISAX® assessments commissioned before 01.10.2020, the previous catalogue can also be used until 31.03.2021.



Anyone who has properly implemented and lived VDA-ISA 4.1.1 in the past can switch to the new VDA-ISA catalogue 5.0 with little effort and easily implement the additional requirements.
