TL;DR: Connected vehicle ecosystems depend on V2X, supplier access, and machine-to-machine trust, which expands the identity surface far beyond the vehicle itself, according to CyberArk. The governance challenge is not simply stronger authentication but controlling non-human identities, privileged pathways, and lateral movement across manufacturing and operational systems.
Editorial analysis by NHI Mgmt Group, based on content published by CyberArk: “How Secure is Automotive Digital Identity?”.
Key questions
Q: What breaks when automotive identity is treated as a vehicle login problem only?
A: Teams miss the real control plane, which sits across suppliers, factory systems, administrators, applications and machines.
Q: Why do connected vehicle ecosystems create more identity risk than traditional product environments?
A: Because they depend on continuous machine-to-machine trust.
Q: What signs show that automotive privileged access is out of control?
A: Look for shared administrator credentials, machine accounts with broad scope, supplier access that outlives the project, and authentication events that cross business domains without correlation.
Practitioner guidance
- Map the automotive privileged pathway Document which identities can move from suppliers or enterprise systems into design, factory and vehicle-support environments, then remove unnecessary cross-domain access.
- Inventory non-human identities in production chains Build a registry of application, machine and integration credentials that touch blueprints, production secrets and connected-vehicle data.
- Separate V2X trust from enterprise access Define which identities are allowed to authenticate V2X-related services and keep those paths isolated from general administrative access.
Bottom line: Automotive digital identity expands the attack surface into manufacturing, supplier and vehicle-connected systems, so identity governance has to follow the trust chain rather than the individual login.

Automotive digital identity is now a governance problem, not a point-control problem. The article shows that connected vehicles, factory systems, suppliers and operators all sit inside one trust environment. That means identity decisions made for one system can affect manufacturing, road safety and data handling elsewhere. Practitioners should govern the whole identity chain, not just the login screen.
A question worth separating out:
Q: Should automotive teams govern supplier access like internal privileged access?
A: Yes, because supplier identities often reach the same blueprints, production systems and connected-vehicle services that internal teams protect. The governance standard should be the same even if the business relationship is different. If a third party can touch operational assets, its access needs lifecycle control, monitoring and fast revocation.
