TISAX Explained: Understanding Scope, Impact, and the Certification

The automotive industry is accelerating toward a future of autonomous vehicles, robotaxis, and connected mobility. But as innovation speeds up, so do cyber threats—95% of automotive cyberattacks are remote, posing risks like hijacked vehicles or compromised braking systems.

To secure this complex, data-driven landscape, the industry increasingly turns to TISAX (Trusted Information Security Assessment Exchange).

TISAX helps standardize how companies handle sensitive data by enforcing explicit assessment scopes, confidentiality levels, and a verifiable audit trail, making it a rising benchmark for building trust and resilience in modern mobility ecosystems.

What is TISAX?

TISAX (Trusted Information Security Assessment Exchange) is a globally recognized standard for information security, especially in the automotive industry. Developed by the German Association of the Automotive Industry VDA in collaboration with the ENX Association, the standard ensures secure data handling and information exchange across organizations.

The VDA sets out the security requirements in the information security assessment (ISA), and ENX oversees the certification process. The standard builds upon the established controls of ISO 27001, the gold standard for information security, while customizing them according to automotive industry needs.

What TISAX Aims to Achieve?

TISAX (Trusted Information Security Assessment Exchange) seeks to create a standard for checking and sharing information security in the automotive supply chain. It is based on ISO 27001 and tailors security controls to the industry’s needs.

The framework is designed to:

– Protect sensitive information like intellectual property, personal data, and confidential contracts.

– Allow secure and efficient teamwork between OEMs, suppliers, and service providers.

– Minimize audit fatigue with a single, widely accepted assessment.

– Boost market credibility and increase compliance transparency across the supply chain.

Why TISAX is Important for the Automotive Industry  

While not required, TISAX has become a standard expectation for businesses that work with OEMs and Tier 1 suppliers. Here’s why:

– Better Data Protection: TISAX implements strong security measures to protect valuable automotive data from breaches.

– Sales Enablement: Certification builds customer trust and can help revive stalled deals or secure new contracts.

– Audit Efficiency: Multiple partners accept one TISAX assessment, reducing the need for repeated checks.

– Lower Implementation Costs: Companies already compliant with ISO 27001 can use existing controls, saving time and resources.

What are the Key Components of TISAX Frameworks

TISAX primarily targets companies in the European automotive industry supply chain that handle sensitive information. However, many multinational companies require global partners and suppliers to comply with TISAX. This makes it relevant for international organizations wishing to enter into business contracts with European firms.
The following entities fall under TISAX:

• Original Equipment Manufacturers (OEMs): Companies that develop, assemble, and market vehicles.
• Suppliers and sub-suppliers: Companies that provide parts, systems, and components for manufacturing vehicles. This also includes sub-suppliers that provide raw materials or components to leading suppliers.
• Service Providers: Organizations that offer services related to IT, engineering, consulting, and data processing and handle sensitive information
• Research and Development Firms: Organizations that are involved in prototype creation, design, or innovation
• Other partners: Companies offering logistics and transportation services

Other key aspects of TISAX Scope:

ISMS: Organizations must establish a fully compliant ISMS aligned with ISO 27001 and TISAX requirements.

Data Categories: Entities falling under TISAX must protect prototypes and product development data, operational and business process information, customers’ personal information, and third-party and partner information exchange.

What are the Assessment Levels of TISAX

Depending on the data’s sensitivity, the organization’s importance in the automotive supply chain, and the maturity of information security controls, TISAX conducts assessments at 3 levels. These levels represent the depth and scope of the assessment.

Let’s dive deep into these 3 levels:

Assessment Level 1 (AL1)

This introductory level suits organizations that handle non-sensitive data such as general business information.

• Organizations must implement foundational security controls such as access controls and incident response plans
• Organizations complete a survey or a questionnaire as per the TISAX standard to undergo a self-assessment and prepare a self-assessment report
• No external verification or audit is required in this case
• No TISAX label is issued, and the self-assessment report is shared with clients on request

Assessment Level 2 (AL2)

AL2 is a slightly advanced level suitable for organizations handling medium-risk data, such as some personal data, supplier information, intellectual property, and internal communication.

• Organizations must implement additional security controls, such as data encryption, advanced access controls, regular security audits, a formalized incident response plan, and data integrity and protection protocols
• It requires a self-assessment and a partial evaluation conducted by a chosen TISAX-accredited auditor
• The auditor reviews documentation and may conduct interviews to identify any deficiencies
• The final report is issued by the auditor after gap remediation, and the organization receives a TISAX label

Assessment Level 3 (AL3)

Level 3 is for organizations that deal with highly sensitive data, such as prototype information, personal data protected under GDPR, critical systems data, or confidential information.

• Organizations must implement a mature ISMS and advanced measures such as advanced encryption standards, continuous monitoring, awareness training, risk assessments, and data loss prevention measures.
• It requires an on-site audit by the TISAX-accredited auditor
• The auditor conducts an in-depth evaluation of the controls and issues a TISAX label
• Leading automotive manufacturers require AL3 as it offers the highest level of assurance

Exchange Size and Growth of TISAX

TISAX is currently said to be the second most widely adopted information security standard. Over the years, its adoption has expanded beyond the automotive industry, and organizations across the globe are realizing its value in data protection and strengthening partnerships.

• Number of Registered Participants: Over 10,000 locations have been assessed across 80 countries, with more than 3000 registered TISAX participants. The increasing number of companies joining the network highlights the strong demand for trusted suppliers in the automotive industry who have undergone formal assessments.
• Regional and Global Reach: TISAX is expanding its influence across other regions, especially North America and Asia, after establishing a strong foothold in the European automotive industry. AWS has recently achieved TISAX certification across 19 regions and is a notable example of how the standard is globally recognized for information security in supply chains.
• Industries Beyond Automotive: TISAX requirements are recognized as valuable beyond the automotive sector because of its strong emphasis on information security. Sectors such as aerospace, rail manufacturing, energy, and defense also adopt TISAX principles to safeguard sensitive information.

The Roadmap to Achieving TISAX Certification

For TISAX attestation, the VDA suggests you take a self-assessment using the ISA (Information Security Assessment) questionnaire. It’ll help you understand your ISMS’s maturity level.
The ISA also ranks these maturity levels from 0 (incomplete) to 5 (optimizing) based on whether or not structured processes are in place. Organizations must reach a minimum of level 3 (established) to receive the TISAX label.

The TISAX certification process has 4 phases:

1. Preparation

The preparation phase involves the following steps:

Familiarize yourself with the requirements

Begin by understanding the TISAX requirements and familiarizing yourself with the VDA questionnaire, which covers data protection and prototyping security.

Determine the scope and assessment level

Next, identify the systems and processes eligible for evaluation and determine the assessment level based on the sensitivity of the information you handle.

Conduct a review of existing policies and processes

Identify the weaknesses in your ISMS and review existing policies and processes to pinpoint the gaps per TISAX requirements. This is like a self-assessment to understand your current security maturity. Some common areas of improvement include risk assessments, access controls, incident response plans, and data protection controls.

Remediate the gaps

Implement the required security enhancements such as encryption, MFA, data classification policies, and role-based access controls. Also, train your employees on security best practices and create solid documentation of corrective actions.

2. Registration

Go to the ENX Association website and create an account on the TISAX portal for registration. You’ll be required to enter details such as the organization’s name and contact information, scope of assessment, and assessment levels. From the portal, choose a TISAX-accredited audit provider and agree on terms such as timeline and costs.

3. Assessment by an accredited auditor

Coordinate with the chosen TISAX auditor regarding the audit scope, schedule, and documentation. The auditor will conduct an in-depth assessment of the ISMS, security measures, and prototyping security as part of compliance verification against TISAX objectives.

The auditor compiles a report with detailed findings after interviews with staff, process walkthrough, and documentation review.

For any gaps identified, the organizations have nine months to implement remediation and undergo follow-up assessments.

If the organization meets the criteria, the auditor submits the report to ENX, and the company gets a TISAX label. You can selectively share the results with trusted partners through the ENX portal, as the results are not public for everyone.

4. Ongoing Monitoring and Improvements

Once you’ve received the label, you will only be reassessed after 3 years. However, you must display an ongoing commitment to security. Establish a continuous monitoring mechanism to proactively address security gaps and regularly review and update your ISMS to minimize risks.

TISAX vs ISO 27001: Key Differences

While TISAX builds on ISO 27001, there are several key differences between the two:

Feature	TISAX	ISO 27001
Industry Focus	Automotive-specific	Industry-agnostic (applies across all sectors)
Governing Body	VDA (requirements) + ENX (oversight)	International Organization for Standardization (ISO)
Assessment Approach	Three-tiered (AL1, AL2, AL3) based on data sensitivity	Single-level certification
Audit Model	Varies by level – from self-assessment to full external audit	An external audit is required for certification
Confidentiality Levels	Explicit confidentiality levels are set per scope and data type	The organization defines confidentiality requirements
Exchange Network	Results shared selectively through the ENX portal	No standardized platform for result sharing
Recognition in Automotive	Widely accepted and often expected by OEMs and suppliers	Often a prerequisite, but not tailored to automotive needs

In essence, TISAX tailors ISO 27001 for the automotive industry. It streamlines compliance, cuts down on repetitive audits, and fosters trust within the automotive exchange network.
