Putting this into practice
Winners Consulting helps organizations turn this concept into workable policies, processes and audit readiness.
Step 1 of 3
You looked up “Over-the-air (OTA) software updates”. Which situation is closest to yours?
Common situations behind “Over-the-air (OTA) software updates” and the first step
- An OEM asks component suppliers for vehicle cybersecurity engineering evidence：Set up TARA and a cybersecurity development process with traceable work products
- Vehicle type approval must address UN R155：Separate the evidence each of UN R155, TISAX and 21434 requires
- You need an advisor who knows automotive cybersecurity：Check that the advisor handles both process and engineering, not just templates
Winners Consulting provides ISO/SAE 21434 vehicle cybersecurity consulting. Vice-president and director-level consultants lead the work end to end with no outsourcing, and one set of evidence answers several laws and customer requirements.
Before choosing a consultant or budgeting: decision guides
Use these guides as a checklist when comparing consultants and estimating budget and timeline.
- Budgeting for TISAX next year: how to estimate itA TISAX budget consists of the ENX registration fee, the audit provider's assessment fee, consulting and internal effort; assessment objectives, number of sites and information-security maturity determine the amount.
- How long does TISAX take, and which steps cannot be compressed?ENX cannot estimate the overall timeline; what you can control is the order of the three steps: registration, assessment and exchange. Automotive digital products may also be governed by the CRA.
- How to choose a TISAX consultant in Taiwan: eight criteriaWhen choosing a TISAX consultant, first check whether they can define the assessment scope and objectives correctly and make the right call between AL2 and AL3; automotive digital products also need the CRA considered at the same time.
- How to choose an ISO/SAE 21434 consultant in Taiwan: eight criteriaWhen choosing an ISO/SAE 21434 consultant, first check whether they can tell apart the three requirements carmakers raise (UN R155, TISAX and 21434); then whether they can build threat analysis and risk assessment (TARA), cybersecurity requirements and verification into your existing development process so that it stands up to the carmaker's project audit.
