Preparing for TISAX® audit: Key checklist for businesses

What is a TISAX® audit?  

A TISAX® (Trusted Information Security Assessment Exchange) audit is a standardized assessment process developed by the German Association of the Automotive Industry (VDA) and managed by the ENX Association. The TISAX® audit is the testing process for obtaining a TISAX® label. It aims to ensure high levels of information security across the automotive supply chain.  

Based on the VDA Information Security Assessment (VDA ISA) catalog, which aligns with ISO/IEC 27001, the audit evaluates an organization’s data protection, risk management, and physical security measures. Results are shared on the TISAX® platform, enhancing trust and reducing the need for multiple audits by different partners. 

What is the main goal of the TISAX® audit? 

The main goal of the TISAX® audit is to ensure and verify high standards of information security across the automotive industry’s supply chain. This standardized assessment helps organizations protect sensitive data, manage risks effectively, and comply with industry-specific security requirements. By doing so, TISAX® enhances trust and credibility among business partners and customers, facilitating secure and reliable information exchanges within the automotive sector. 

What are assessment levels, and what are their main types?   

There are three TISAX® assessment levels (AL), each reflecting different degrees of information security requirements. 

TISAX® Level 1: Basic protection 

This level is for organizations handling general business information. Assessments focus on basic security measures like password management, secure data storage, and access control. Organizations at this level must ensure a basic level of security for non-sensitive information. 

TISAX® Level 2: Advanced protection 

Level 2 is for organizations handling sensitive information, such as intellectual property or personal data. This assessment is more thorough, covering additional controls like data classification, protection, and encryption. Organizations at this level must follow stricter security standards to protect sensitive information. 

TISAX® Level 3: Enhanced protection 

This level is for organizations dealing with highly sensitive information, such as prototypes or confidential projects. The assessment is very rigorous, focusing on advanced security measures like strict access controls, enhanced monitoring, and detailed incident response procedures. Companies at this level must have strong security measures to protect highly sensitive data. 

TISAX® has eight different test objectives. A company can get eight different labels according to TISAX®.  

	TISAX® test objective	Assessment Level (AL)
1	Handling information with a high need for protection	AL 2
2	Handling information with a very high need for protection	AL 3
3	Protection of prototype parts and components	AL 3
4	Protection of prototype vehicles	AL 3
5	Handling test vehicles	AL 3
6	Protection of prototypes during events and film/photo shoots	AL 3
7	Data protection (according to Art. 28 GDPR)	AL 2
8	Data protection with special categories of personal data	AL 3

Three TISAX® assessment levels also describe the auditor’s activities during the audit. 

At AL 1, the auditor does not participate. The company provides a self-assessment of its information security management system (ISMS), which is not further questioned or checked. AL 1 is formal and doesn’t result in any test label, so it isn’t practically used. 

For AL 2, the company must complete the VDA ISA questionnaire and send it along with complete ISMS documentation to the selected auditor. The auditor reviews these documents and prepares for an audit interview, which is conducted remotely. 

The main difference between AL 3 and AL 2 is how the audit is done. At AL 3, the audit is conducted in person. The auditor visits the company to ensure that the ISMS guidelines and measures are effectively implemented.

How does a TISAX® audit work? 

Companies must register for the TISAX® process through the ENX online portal, where they specify their desired audit objectives. 

After registering and selecting the audit objectives, companies can choose an accredited audit service provider to conduct the audit. They need to provide the auditor with the completed VDA ISA questionnaire and documentation of their ISMS. The auditor reviews these documents, checks the relevant evidence, and performs a remote or on-site audit before issuing the TISAX® label(s). 

The VDA ISA questionnaire includes a self-assessment of how well each measure has been implemented. The auditor verifies this information by requesting suitable evidence. Simply creating internal guidelines and policies is not enough. TISAX® participants must demonstrate that they follow these guidelines. 

Who needs a TISAX® certificate? 

A TISAX® certificate is needed by organizations within the automotive industry that handle sensitive information and need to demonstrate their compliance with high standards of information security.  

Such organizations include: 

• Automotive manufacturers (OEMs): Companies that design, produce, and sell vehicles. 
• Automotive suppliers and vendors: Organizations that provide parts, components, or services to automotive manufacturers. 
• Automotive service providers: Businesses that offer IT, logistics, consulting, or other services to the automotive sector. 
• Automotive partners and subcontractors: Entities involved in collaborative projects or who have access to sensitive information shared by automotive companies. 

Obtaining a TISAX® certificate helps these organizations demonstrate their commitment to information security, meet industry requirements, and build trust with their business partners. 

The main benefits of TISAX® audit 

The TISAX® audit offers several key benefits for organizations looking to enhance their information security practices and meet the security requirements of their partners or customers, including: 

• Enhanced security posture: The TISAX® audit helps organizations identify and address security gaps, leading to a stronger and more resilient security posture. 
• Compliance with standards: TISAX® compliance demonstrates that an organization meets the security requirements of the automotive industry, which can be a competitive advantage when working with automotive manufacturers and suppliers. 
• Improved risk management: By conducting a TISAX® audit, organizations can better understand and manage their information security risks, reducing the likelihood of security incidents. 
• Enhanced customer trust: TISAX® compliance demonstrates to customers and partners that an organization takes information security seriously, which can help build trust and credibility. 
• Cost savings: While the initial investment in a TISAX® audit may be significant, achieving compliance can lead to cost savings in the long run by reducing the likelihood of security breaches and associated costs. 
• Competitive advantage: TISAX® compliance can give organizations a competitive advantage in the automotive industry by demonstrating their commitment to security and compliance. 
• Global recognition: TISAX® is recognized internationally as a standard for information security in the automotive industry, which can be beneficial for organizations operating in multiple regions. 

Overall, the TISAX® audit can help organizations improve their security posture, build trust with customers and partners, and achieve a competitive advantage in the automotive industry. 

How long does a TISAX® audit take? 

Preparing for a TISAX® audit can take weeks, months, or even years. However, the actual TISAX® assessment only takes a few days at most. The duration depends on the TISAX® label you want and your company’s structure. 

A company with many international locations and needing an on-site audit at Assessment Level 3 will need more time compared to a company with one location and an audit at AL 2. This is true even if the audit service provider has international teams to share the workload.
