What Is TISAX? A Guide for UK Businesses
As cyber security becomes an increasingly important part of doing business, organisations are facing greater pressure to demonstrate that they can protect sensitive information. For businesses working within the automotive industry, one framework has become particularly important: TISAX®.
Whether you're bidding for work with a major vehicle manufacturer, joining an automotive supply chain or responding to customer requirements, understanding TISAX is becoming essential.
In this guide, we'll explain what TISAX is, why it matters and how your organisation can prepare for a successful assessment.
What Is TISAX?
TISAX, which stands for Trusted Information Security Assessment Exchange, is an information security assessment and exchange mechanism developed specifically for the automotive industry. It provides a consistent way for organisations to demonstrate that they have implemented appropriate information security measures when handling sensitive business information.
The framework was developed by the ENX Association on behalf of the German Association of the Automotive Industry (VDA). Rather than every manufacturer creating its own security audit, TISAX provides a common approach that is recognised across much of the automotive sector.
Once an organisation has successfully completed its assessment, the results can be shared with participating customers through the TISAX platform, helping to reduce duplicated audits and simplify supplier assurance.
Why Is TISAX Important?
Modern automotive supply chains rely on organisations sharing large amounts of confidential information. Engineering drawings, product designs, manufacturing data, intellectual property and customer information often pass between manufacturers, suppliers and technology partners.
Without consistent security standards, every customer would need to perform their own cyber security assessment before sharing information.
TISAX helps solve this problem by providing a recognised assessment framework that demonstrates an organisation has implemented appropriate information security controls. This helps build trust between businesses while reducing the need for multiple independent security audits.
For many suppliers, achieving TISAX is no longer simply a competitive advantage. Increasingly, it is becoming an expectation when working with leading automotive manufacturers and their supply chains.
Who Needs TISAX?
Although TISAX was developed for the automotive industry, it isn't limited to vehicle manufacturers.
Any organisation that handles sensitive information on behalf of automotive companies may be asked to complete a TISAX assessment. This includes manufacturers, engineering businesses, software developers, logistics providers, research organisations, design agencies, IT providers and professional service companies that support the automotive sector.
Even if your organisation has never previously been asked about TISAX, customer requirements can change quickly. Many businesses begin preparing before it becomes a contractual requirement, allowing them to respond confidently when new opportunities arise.
How Does TISAX Work?
Unlike a traditional certification programme, TISAX is an assessment framework. Organisations first determine the scope of the assessment and identify the objectives that apply to their business.
An approved TISAX assessment provider then evaluates the organisation against the relevant requirements. The depth of the assessment depends on the assessment objectives and the level of assurance required by customers.
Once the assessment has been completed successfully, the results can be shared securely with customers through the TISAX platform. This enables organisations to demonstrate their security posture without repeating multiple assessments for different customers.
What Does TISAX Assess?
TISAX focuses on how well an organisation protects sensitive information throughout its business operations.
Assessments consider whether appropriate technical controls, governance, risk management processes and operational procedures are in place to reduce information security risks. Depending on the assessment objectives, organisations may also need to demonstrate how they protect confidential information, secure business processes and manage information across their supply chain.
Rather than concentrating on a single technology or security product, TISAX evaluates how effectively information security is managed across the organisation as a whole.
How Long Does TISAX Take?
There is no single timescale for achieving TISAX because every organisation starts from a different position.
Businesses with mature information security processes may be ready for assessment relatively quickly, while others may first need to strengthen their technical controls, improve governance, update documentation or implement additional security measures.
Preparing properly before an assessment is often the most important factor in achieving a successful outcome.
Is TISAX the Same as ISO 27001?
Although TISAX and ISO 27001 both focus on information security management, they are not the same.
ISO 27001 is an internationally recognised standard for information security management systems that can be applied across almost any industry.
TISAX, on the other hand, has been developed specifically for organisations working within the automotive sector. It incorporates automotive-specific assessment requirements and provides a standardised way for organisations to demonstrate information security to manufacturers and suppliers.
Many organisations use the principles of ISO 27001 to support their preparation for TISAX, but one does not automatically replace the other.
Preparing for TISAX
Preparing for TISAX begins with understanding your current information security posture.
Many organisations already have strong technical controls in place but discover they need to improve governance, strengthen documentation or formalise internal processes before they are ready for assessment.
Taking the time to identify gaps before beginning the assessment process can reduce delays, improve cyber resilience and help organisations approach TISAX with confidence.
Frequently Asked Questions
-
TISAX is not a legal requirement. However, many automotive manufacturers and suppliers require organisations to complete a TISAX assessment before sensitive information can be shared or contracts can be awarded.
-
TISAX was developed by the ENX Association on behalf of the German Association of the Automotive Industry (VDA). The ENX Association manages the TISAX programme and the platform used to exchange assessment results.
-
Yes. Organisations of all sizes can prepare for and complete a TISAX assessment. The appropriate assessment objectives and scope will depend on the work your business undertakes and the information you handle.
-
No. Although both frameworks focus on information security, they serve different purposes. ISO 27001 is an international information security management standard, while TISAX is an automotive-specific assessment framework.
-
TISAX assessment results have a defined period of validity, after which organisations must complete a reassessment to maintain their status. Planning for continual improvement helps make future assessments significantly easier.
-
No. Sunrise Technologies helps organisations prepare for TISAX by improving cyber security, strengthening governance and supporting assessment readiness. Official TISAX assessments are carried out by approved TISAX assessment providers.
How Sunrise Technologies Can Help
Preparing for TISAX is about far more than passing an assessment. It requires organisations to understand their current cyber security maturity, identify potential weaknesses and implement practical improvements that strengthen information security across the business.
At Sunrise Technologies, we help organisations prepare for TISAX by reviewing their existing security controls, identifying areas for improvement and supporting the technical and organisational changes needed before assessment. Whether you're responding to customer requirements or planning for future opportunities within the automotive sector, our team can help you build a practical roadmap towards TISAX readiness.
