TISAX Requirements – Understanding the VDA ISA Catalog and Control Domains

TISAX Requirements are based on the VDA Information Security Assessment (VDA ISA) catalog, developed by the German Association of the Automotive Industry. These requirements span information security management, and where applicable, prototype protection and data protection control domains. Understanding these requirements in detail helps organizations plan an accurate and complete preparation ahead of their formal TISAX assessment.

TISAX Requirements

Meeting TISAX requirements means implementing controls that align with the VDA ISA catalog's structured control domains, covering areas such as information security policies, organization of information security, human resources security, physical and environmental security, access control, and incident management. Depending on the assessment objective selected, organizations may also need to implement additional controls specific to prototype protection or data protection.

TISAX Requirements are structured around the VDA ISA catalog, a detailed control framework covering information security management alongside optional prototype and data protection modules.

Understanding the full scope of TISAX requirements before beginning implementation helps organizations avoid both under-preparation and unnecessary effort on controls outside their assessment objective.

What Are the Core TISAX Requirements?

TISAX Requirements Requirements center on the VDA ISA catalog's information security control domains, covering organizational security policy, risk management, asset management, access control, cryptography, physical security, operations security, supplier relationships, incident management, and business continuity. Organizations pursuing the prototype protection objective must additionally address physical and organizational controls specific to protecting vehicles, components, and confidential materials from unauthorized disclosure.

Organizations pursuing the data protection objective must demonstrate controls aligned with data protection principles relevant to personal data processed within their automotive industry relationships. Across all objectives, the VDA ISA catalog uses a maturity-based scoring model, requiring organizations to demonstrate not just the existence of controls, but their consistent, monitored, and continually improved implementation.


Why Understanding Requirements Matters

Organizations that clearly understand TISAX requirements before beginning implementation are better positioned to build a compliant information security program efficiently, focusing effort on the control domains relevant to their specific assessment objective. A precise understanding of the requirements also reduces the risk of an unfavorable assessment result, since the VDA ISA maturity model specifically evaluates whether controls are genuinely embedded in day-to-day operations, not just documented on paper.


Meeting TISAX Requirements : A 10-Step Approach

1. Review the VDA ISA Catalog

Study the control domains and maturity model relevant to your selected assessment objective.

2. Confirm Applicable Objective

Determine whether information security, prototype protection, data protection, or a combination applies to your organization.

3. Establish Information Security Policy

Develop and formally approve an information security policy aligned with VDA ISA expectations.

4. Implement Risk Management Processes

Establish a structured process for identifying, assessing, and treating information security risks.

5. Implement Access Control Measures

Establish controls governing user access, authentication, and authorization across systems and facilities.

6. Address Physical Security Requirements

Implement physical safeguards for facilities handling sensitive automotive information or prototypes.

7. Implement Supplier and Third-Party Controls

Establish requirements for managing information security risk across your own supplier relationships.

8. Establish Incident Management Processes

Implement processes for detecting, reporting, and responding to information security incidents.

9. Demonstrate Maturity Through Evidence

Gather operational evidence showing controls are consistently applied, monitored, and improved over time.

10. Prepare for Objective-Specific Requirements

Address any additional prototype protection or data protection controls relevant to your assessment objective.

A clear, methodical approach to meeting TISAX Requirements helps organizations build a compliant, assessment-ready information security program without unnecessary rework.

TISAX Requirements Success Story

  • Precision Parts Manufacturer Closed Physical Security Gaps: A precision automotive parts manufacturer had strong IT security controls but weak physical security around prototype storage areas. TopCertifier helped implement the physical safeguards required under the prototype protection objective.
  • Software Integrator Clarified Applicable Control Domains: A software integrator serving automotive clients was unsure which VDA ISA control domains applied to its cloud-based services. TopCertifier helped scope and prioritize the relevant requirements.
  • Logistics Provider Strengthened Supplier Management Controls: A logistics provider handling automotive parts strengthened its own supplier and third-party risk management controls with TopCertifier's guidance, meeting a key VDA ISA requirement ahead of assessment.

These success stories show how a precise understanding of TISAX requirements helps organizations focus their preparation effort effectively, addressing the specific control domains and maturity expectations relevant to their assessment objective.

Why Choose TopCertifier to Help You Meet TISAX Requirements?

TopCertifier helps organizations interpret and apply the VDA ISA catalog's control domains accurately, based on their specific assessment objective and scope, rather than a generic checklist.

Our team ensures your documentation, implemented controls, and operational evidence meet the maturity expectations of the VDA ISA model, reducing the risk of an unfavorable outcome during your formal assessment.

Frequently Asked Questions


The core requirements are based on the VDA ISA catalog's information security control domains, along with optional prototype protection and data protection modules.

The VDA ISA catalog is the assessment framework developed by the German Association of the Automotive Industry that defines TISAX control requirements and maturity levels.

No, prototype protection requirements only apply to organizations whose assessment objective includes handling of vehicles, components, or confidential prototype materials.

The VDA ISA catalog uses a maturity-based scoring model that evaluates not just whether controls exist, but how consistently and effectively they are implemented and improved.

Yes, organizations must demonstrate they manage information security risk within their own supplier and third-party relationships.

Organizations must implement controls governing user authentication, authorization, and access management across relevant systems and facilities.

Yes, a formally approved information security policy is a foundational requirement under the VDA ISA catalog.

Data protection requirements focus specifically on the handling of personal data, while information security requirements cover the broader protection of confidential business and technical information.

Unmet requirements typically result in a lower maturity score or an unfavorable assessment outcome, requiring corrective action before the result can be finalized.

A structured gap analysis against the VDA ISA catalog, scoped to your specific assessment objective, is the most reliable way to confirm your organization meets all applicable requirements.
