A global Tier-1 automotive supplier needed to protect the provisioning and management of sensitive credentials and firmware used in embedded Electronic Control Units (ECUs) across their supply chain. With increasing risks from unauthorized access, rogue diagnostics, and counterfeit components, the customer turned to OmniTrust to automate and secure the lifecycle of ECU authentication—from initial password generation to in-field service validation.
