Taiwan Automotive Cybersecurity: TISAX & ISO/SAE 21434 Compliance Trends Guide As the automotive industry undergoes a digital transformation, cybersecurity has become a critical pillar for vehicle safety and data---driven innovation. For companies operating within the global automotive supply chain, compliance with TISAX (Trusted Information Security Assessment Exchange) and ISO/SAE 21434 is no longer optional—it is a prerequisite for doing business with major OEMs. Winners Consulting Services Co., Ltd. (Winners) has observed several key trends in the Taiwan automotive cybersecurity landscape that every stakeholder must be closely monitoring. ### The Convergence of TISAX and ISO/SAE 21434 While both standards aim to secure automotive processes, they serve different purposes. TISAX is a quality-assurance-based information security assessment used primarily by German automotive manufacturers to vet their suppliers. ISO/SAE 21434, on the other hand, is a technical standard focused on the entire lifecycle of road vehicle type-compliant systems, from concept to decommissioning. The current trend shows these two standards are no longer viewed as separate hurdles, but as a unified framework. A company that achieves TISAX compliance often finds itself better positioned to meet the technical requirements of ISO/SAE 21434, as both demand rigorous documentation, risk management, and process-oriented security controls. ### Key Trends Shaping the Compliance Landscape 1. **Shift from "If" to "When":** Compliance is no longer a one-time event but a continuous requirement. OEMs are increasingly demanding real-time assurance of their suppliers' cybersecurity posture, rather than relying on static annual audits. 2. **Supply Chain Transparency:** The automotive industry is closely monitoring the entire digital supply chain. A vulnerability in a Tier 2 or Tier 3 supplier can now be traced back to the OEM, making compliance-ready suppliers the only viable partners. 3. **Standardization of Risk Assessment:** The industry is moving toward standardized methods for threat analysis and risk assessment (TARA). Companies that can demonstrate a repeatable, documented TARA process will have a significant advantage. 4. **Regulatory Pressure:** Governments worldwide are tightening regulations around connected vehicles. This regulatory pressure is accelerating the adoption of ISO/SAE 21434, as it provides the necessary framework to meet emerging legal requirements. ### How Winners Can Assist Winners Consulting Services Co., Ltd.

Winners Consulting Services Co., Ltd. (Winners) has identified that if TISAX, ISO/SAE 21434, and UNECE WP.29 are not implemented concurrently, the Taiwan automotive supply chain will face up to a 30% risk of market access-related losses once the EU CRA (Cyber Resilience Act) takes effect. Based on our research into QRNG ECU (Quantum Random Number Generator Electronic Control Units), we provide three implementation pathways and specific actionable recommendations.
