TISAX® Certification

Your inquiry


Information security in the automotive industry

Are you a supplier or service provider for the automotive industry? Then in future, you will only have to provide proof of the security of sensitive information provided to you by clients once every three years - as a participant in the TISAX® procedure via a corresponding assessment. The procedure is applicable across all industries and defines requirements for information security in your company.

Mutual recognition among all TISAX® participants

Suppliers and service providers achieve greater trust in your audited company

The assessment for TISAX® certification takes place only every three years

Saving time and costs by participating in the TISAX® network

Basic information about the TISAX® assessment

TISAX® is a common assessment and exchange procedure for the automotive sector. It is based on the questionnaire (ISA - Information Security Assessment) developed by the VDA working group "Information Security", which in turn is based on key aspects of the international standard ISO/IEC 27001 and has been extended to include a maturity model.

In addition, the responsible bodies at the German Association of the Automotive Industry (VDA) have created the conditions for establishing the joint assessment and exchange mechanism under the name TISAX® (Trusted Information Security Assessment Exchange).TISAX® is a registered trademark of the ENX Association. The Association of European automotive manufacturers, automotive suppliers and automotive associations monitors the quality of TISAX® assessments and controls the approval of TISAX® audit service providers.

Why is a TISAX® assessment useful for my company?

As a service provider or supplier in the automotive industry, you need to prove to your customers that you comply with information security requirements. Until now, these assessments were primarily performed by the manufacturers themselves. Registered participants in the TISAX® network can now select an audit service provider via a common online platform and request an assessment. The advantages for companies outweigh the disadvantages:

  • Duplicate and multiple assessments by different customers can be avoided
  • Cross-company recognition of information security assessments for TISAX® participants
  • Reliability of results due to the harmonized VDA ISA test catalogue
  • Strengthening of trust in audited companies with TISAX® label

What are the requirements of TISAX®?

The TISAX® assessment and exchange procedure contains the requirements of the VDA Information Security Assessments (ISA). This questionnaire on information security in the automotive industry was developed by the VDA working group. However, TISAX® is also based on essential requirements of ISO 27001 (Information Security Management System).

The industry-specific VDA ISA catalogue has been available in version 5.1 since 2022. This version has been mandatory for all TISAX® audits since October 2020. The requirements from the international and cross-industry standard for information security ISO 27001, in turn, contribute among other things to companies looking beyond the protection of IT technical systems - namely to all corporate assets to be protected.

How does TISAX® work?

In TISAX®, participants can take on two different roles: the "Information Consumer" (passive), for example, is there a manufacturer who would like to receive information about a vendor, and the "Information Contributor" (active), for example, is there a parts supplier or service provider who would like to be audited for suitability in order to receive orders from manufacturers.

A company can also take on both participant roles. Anyone wishing to participate in TISAX® as an Information Contributor must take the following four main steps:

  • 1. Register online at www.enx.com/TISAX
  • 2. Select an ENX-approved audit service provider such as DQS
  • 3. Undergo a TISAX® assessment
  • 4. Exchange the audit results on the TISAX® online platform.

How does a TISAX® assessment work?

The requirements of the scope and the assessment level must be defined by you in advance, for example "with or without prototype protection".

In the first step, you select an approved audit service provider. In the second step, there is a kick-off, the document review (self-assessment, not on-site) and a subsequent assessment (Level 2: not on-site, Level 3: on-site).

Please note: There is an alternative method for conducting an assessment in Assessment Level 2. Instead of a plausibility check, your audit service provider conducts a full remote assessment. This method is sometimes referred to as "Assessment Level 2.5." The advantage of an Assessment Level 2.5 is that the approach is methodologically compatible with Assessment Level 3. It is therefore possible to upgrade to a full Assessment Level 3 exam at a later date with manageable effort.

The findings from the audit are recorded in an interim report. In the event of non-conformities, measures to be implemented are agreed. If necessary, the implementation of measures is determined within an agreed period of time.

After closing the non-conformities, an effectiveness check is carried out by means of an audit.

The final report is posted online on the TISAX® portal. This lists your company as a participant with the corresponding audit label.

What does the TISAX® assessment cost?

Two important factors

Two important factors influence the scope of the entire assessment and thus the costs. Assessments are possible on the basis of an extended scope, a standard scope, or a restricted scope. Your decision for a scope should be well prepared and determined by the desired protection goals, but also by the size of your company.

The protection goals, for example, are about whether you want to include topics such as prototype protection or data protection in the assessment. If you want to get involved in the TISAX® procedure, talk to DQS, your approved audit service provider, as early as possible. This is the only way we can determine the correct calculation for the assessment scope, and provide you with a reliable quote for the cost of your TISAX® certification.
