TISAX Assessment – Understanding Assessment Levels, Objectives, and Scope

A TISAX Assessment evaluates an organization's information security maturity against the VDA Information Security Assessment (VDA ISA) catalog, producing a result that can be shared with automotive partners through the ENX Association exchange platform. Understanding the different assessment levels, objectives, and scope options is essential for selecting the right assessment type and preparing effectively. This guide explains what a TISAX assessment involves and how organizations can approach it strategically.

TISAX Assessment

Before undergoing a TISAX assessment, organizations must determine which assessment level and objective best matches their business requirements and the expectations of the OEMs or partners requesting the assessment. Assessment levels range from a low-level self-assessment to higher levels involving on-site or remote review by an accredited audit provider, while assessment objectives determine which specific control domains, information security, prototype protection, or data protection, are evaluated.

TISAX Assessment requires organizations to first determine the appropriate assessment level and objective, since these choices shape both the scope of controls reviewed and the depth of evidence required.

Selecting the correct TISAX assessment level and objective from the outset helps organizations avoid unnecessary rework and ensures the resulting label meets partner expectations.

What Does a TISAX Assessment Involve?

TISAX Assessment Assessment involves organizations selecting an assessment level, ranging from Assessment Level 1 (self-assessment) through higher levels that require review by an accredited audit provider, and an assessment objective covering information security, and where relevant, prototype protection or data protection. The assessment itself evaluates documented policies, implemented controls, and operational evidence against the VDA ISA question catalog.

Once an assessment is successfully completed at the required level, the organization receives a TISAX label and assessment result that can be shared with specific partners via the ENX Association platform. Sharing is controlled by the assessed organization, allowing it to selectively grant visibility of its result to relevant OEMs and business partners without repeating separate individual audits for each relationship.


Why Understanding the Assessment Structure Matters

Organizations that understand the structure of TISAX assessments, including levels, objectives, and scope, before beginning preparation are better positioned to select the right assessment type for their specific partner requirements and avoid wasted effort. Since different OEMs and partners may request different assessment levels or objectives, organizations working with multiple automotive partners benefit from understanding how scope and objective selection affects the applicability of a single assessment result across their partner relationships.


Preparing for Your TISAX Assessment : A 10-Step Approach

1. Determine Required Assessment Level and Objective

Confirm with your OEM or partner which assessment level and objective (information security, prototype protection, data protection) is required.

2. Define Assessment Scope

Identify the locations, business units, and processes that will fall within the assessment scope.

3. Register on the ENX Portal

Create your organization profile and initiate the assessment process through the ENX Association platform.

4. Conduct a Readiness Gap Analysis

Assess current practices against the VDA ISA catalog requirements relevant to your selected objective and level.

5. Develop Required Documentation

Prepare information security policies, procedures, and evidence required to support your assessment.

6. Implement Missing Controls

Address control gaps identified during the readiness review before the formal assessment.

7. Train Relevant Personnel

Ensure employees involved in information security processes understand their roles and responsibilities.

8. Conduct an Internal Mock Assessment

Simulate the assessment internally to identify any remaining gaps in evidence or implementation.

9. Undergo the Formal Assessment

Complete the assessment with an accredited audit provider at the confirmed level.

10. Share Your Result

Grant visibility of your assessment result to relevant partners through the ENX platform.

A structured approach to preparing for your TISAX Assessment helps ensure a smooth process and a result that meets your partners' expectations.
