DigiCert Device Trust Manager is an IoT security platform that provides end-to-end certificate lifecycle management for connected devices, covering the full device lifespan from manufacturing through retirement. The platform addresses four key phases of the device lifecycle: - Design: Supports crypto agility and post-quantum cryptography (PQC) readiness, secure hardware via TPMs and Secure Elements, and a TrustEdge agent for foundational security. - Develop: Provides software vulnerability scanning and validated software signing for authenticity and integrity verification. - Build: Enables hardware-backed device identities, in-factory credential provisioning, and birth certificate injection for third-party manufacturers. - Operate: Delivers continuous threat monitoring, secure over-the-air software updates, and zero-touch provisioning. Certificate issuance and management capabilities include batch certificate issuance, on-premises issuance via a gateway, and both birth and operational certificate issuance. Supported provisioning protocols include REST API, SCEP, EST, ACME, CMPv2, and MQTT for system integration. Device Trust Manager supports compliance with multiple regulatory frameworks including EU MDR, EU Cyber Resilience Act, U.S. Cybertrust Mark, FDA regulations, and CSA Matter protocol for smart home interoperability. The product is part of the DigiCert ONE platform alongside CertCentral TLS Manager, Trust Lifecycle Manager, and Software Trust Manager.
