TISAX vs ISO 27001: What's the Difference?
Information security has become a business priority across almost every industry. As organisations look to strengthen their cyber resilience and demonstrate their commitment to protecting sensitive information, two frameworks are often discussed: TISAX® and ISO 27001.
Although they share many similarities, they are not the same. Understanding the differences is important if you're deciding which framework is right for your organisation, particularly if you work within the automotive supply chain.
In this guide, we'll explain how TISAX and ISO 27001 compare, where they overlap and whether your business may benefit from one or both.
What Is TISAX?
TISAX, which stands for Trusted Information Security Assessment Exchange, is an information security assessment framework developed specifically for the automotive industry.
It was created by the ENX Association on behalf of the German Association of the Automotive Industry (VDA) to provide a consistent way for organisations to demonstrate that they protect sensitive information appropriately.
Rather than every automotive manufacturer conducting its own supplier security audit, TISAX provides a common assessment framework whose results can be shared with participating organisations.
What Is ISO 27001?
ISO 27001 is the world's leading international standard for Information Security Management Systems (ISMS).
Published by the International Organisation for Standardisation (ISO), it provides organisations with a structured framework for identifying information security risks, implementing appropriate controls and continually improving their approach to information security.
Unlike TISAX, ISO 27001 is designed for organisations across every industry, from financial services and healthcare to manufacturing, education and technology.
The Biggest Difference
The biggest difference between TISAX and ISO 27001 is who they're designed for.
ISO 27001 is an internationally recognised management system standard that can be implemented by organisations in almost any sector.
TISAX, however, has been developed specifically for businesses operating within the automotive supply chain. It enables suppliers to demonstrate that they meet the information security expectations of automotive manufacturers and other organisations within the industry.
If your organisation has no connection to the automotive sector, ISO 27001 may be the more appropriate framework. If you work with vehicle manufacturers or their suppliers, TISAX may become a customer or contractual requirement.
How Do They Compare?
Both frameworks encourage organisations to adopt a structured, risk-based approach to information security rather than relying on individual technical controls.
They promote good governance, documented processes, continual improvement and the protection of sensitive business information across the organisation.
However, TISAX builds upon these principles with assessment objectives that reflect the specific information security expectations of the automotive industry. Depending on your customers' requirements, assessments may also consider areas such as prototype protection, confidentiality and data protection alongside broader information security practices.
Can ISO 27001 Help You Achieve TISAX?
Yes. Many organisations that have already implemented ISO 27001 discover that they have established many of the governance processes, policies and risk management practices expected during a TISAX assessment.
However, ISO 27001 certification does not automatically result in a successful TISAX assessment. Organisations must still demonstrate compliance with the relevant TISAX assessment objectives and complete an assessment through an approved TISAX assessment provider.
Think of ISO 27001 as providing a strong foundation rather than a direct replacement.
Can You Have Both?
Absolutely. Many organisations choose to maintain both ISO 27001 certification and TISAX assessment results.
ISO 27001 demonstrates internationally recognised information security management, while TISAX provides assurance specifically for organisations operating within the automotive sector.
Together, they demonstrate a mature and comprehensive approach to protecting information while helping organisations meet a broader range of customer expectations.
Which One Is Right for Your Business?
The answer depends on the markets you serve. If your organisation operates across multiple industries and wants an internationally recognised information security management standard, ISO 27001 is often the logical choice.
If you work within the automotive supply chain, your customers may specifically require TISAX. In many cases, organisations choose to implement ISO 27001 principles first before preparing for TISAX, creating a stronger foundation for assessment.
Rather than viewing the two frameworks as competing alternatives, it is often more helpful to see them as complementary approaches to improving information security.
Frequently Asked Questions
-
Neither framework is better than the other. They serve different purposes. ISO 27001 is an international information security management standard, while TISAX is designed specifically for organisations operating within the automotive supply chain.
-
No. Although ISO 27001 provides an excellent foundation for information security, it does not replace a TISAX assessment where customers require one.
-
Yes. Organisations with a mature Information Security Management System often find that many of the governance and risk management principles expected by TISAX are already in place, making preparation more straightforward.
-
TISAX is primarily recognised within the automotive sector and its supply chain. Organisations in other industries are more likely to be asked for ISO 27001 certification or other recognised security standards.
-
Not necessarily, but many organisations find that implementing ISO 27001 principles provides a strong foundation for future TISAX preparation. The right approach depends on your customers' requirements and your organisation's objectives.
