Cybersecurity is playing an increasingly crucial role in the automotive industry, which is made up of a large number of players, all of whom share sensitive information (especially with so-called OEMs).
To address these new challenges, the industry has developed specific standards to ensure the security of the information exchanged. Among these, the TISAX®(Trusted Information Security Assessment Exchange) certification stands out as an essential standard.
This article aims to introduce TISAX®, explaining what this certification entails and why it is essential for companies in the automotive sector.
We'll look at its benefits, its specific requirements, and how it enables companies to strengthen their security while promoting trust between partners.
TISAX® (Trusted Information Security Assessment Exchange) is an information security framework specific to the automotive industry.
Created by the ENX (European Network Exchange) association, with the support of the VDA (German Automotive Industry Association), this label was set up to meet the growing need to protect sensitive data.
First launched in 2017, its main aim is to ensure that all partner companies comply with high security standards, minimizing the risk of cyberattacks and data leaks.
Based on an information security management system similar to ISO 27001, TISAX® is tailored to the requirements of the automotive industry.
The assessment process
The process begins with a self-assessment, during which the company analyzes its compliance with the standard's requirements and identifies potential improvements. It then undergoes an audit by an accredited organization, which assesses the adequacy and effectiveness of the safety measures in place.
Once certified, the certification is valid for three years. Unlike the ISO 27001 certification cycle, no surveillance audits are conducted during those three years. However, since TISAX® requires the implementation and maintenance of an ISMS, compliance with TISAX requirements is expected to be verified on a regular basis, at least once a year.
Firstly, by ensuring compliance with the stringent information security requirements imposed by customers and partners, companies can maintain strong, reliable business relationships.
By adopting TISAX® standards, a company demonstrates its commitment to data protection. This approach strengthens its competitiveness in the market. It becomes possible to attract new customers who are concerned about information security. It also builds trust among existing partners. Finally, it creates a distinct competitive advantage and enables the company to work with certain companies in the automotive sector that require compliance with these standards.
The similarity between the ISO 27001 standard and TISAX® facilitates a potential transition from ISO 27001 to TISAX® or from TISAX® to ISO 27001.
TISAX® promotes the continuous improvement of internal processes related to information security by providing a structured framework that helps organizations identify inefficiencies and implement best security practices.
This reinforcement of processes increases the robustness of information systems and reduces the risk of security incidents.
By adopting a common standard for information security assessments, companies avoid redundant audits. These are often costly and time-consuming. This reduces the cost of the audits themselves. It also reduces the cost of managing security incidents. These incidents can occur as a result of gaps in non-harmonized security practices.
As a result, TISAX® promotes economies of scale and increased efficiency in information security management.
The automotive sector is a very high value-added economy, based on the sharing of confidential information between several partners. Protecting the information system is therefore imperative.
TISAX® assessments focus primarily on three aspects:
In addition, TISAX® uses the ENX platform—a secure network—to facilitate the transparent and secure sharing of assessment results among certified entities.
This approach ensures that all players in the automotive sector adhere to high security standards, which are essential for protecting innovations and strategic information.
There are 3 levels of assessment:
The assessment level is requested by the partner who wants you to be TISAX®-certified.
This self-assessment is based on the VDA's Information Security Assessment (ISA) framework, and ensures that all security processes and policies are well documented and implemented.
This enables a company to diagnose its current information security capabilities.
Preparing for TISAX® certification can be complex, depending on your ISO maturity level. Guidance through the TISAX certification process allows you to structure this effort and approach the audit with confidence.
Secondly, the choice of an audit provider is crucial; it's important to select a partner accredited by theENX Association.
The selection criteria should include industry-specific expertise, references, geographic proximity, and costs. This structured approach ensures optimal preparation for the TISAX® audit and increases the chances of obtaining the certification.
Certification begins with an initial audit, during which the company assesses its compliance with the requirements of the standard.
It's essential to prepare thoroughly, taking into account all the requirements of the ISA standard corresponding to your customer's request.
Following this audit, any discrepancies identified must be corrected by means of corrective actions.
These actions are priorities for obtaining the label, and must be rigorously documented and monitored to guarantee their effectiveness.
If only minor deviations have been identified, then you have 9 months to correct all deviations. During this time, you'll have a "temporary" label.
Implementing TISAX® offers significant benefits, including improved protection of sensitive data, a greater competitive advantage, and enhanced trust among business partners.

Looking ahead, future developments in TISAX® could include adaptations to new technological threats and responses to evolving international regulations, thereby ensuring that the certification remains at the forefront of information security. These developments will continue to shape standards in the automotive and cybersecurity industries.
