Azure Certified Device
Azure Certified Device certification validates that a device can connect with Azure IoT Hub and securely provision through the Device Provisioning Service (DPS). This IoT validation reflects a device's functionality and interoperability, which are a necessary baseline for more advanced certifications.
IoT Plug and Play
IoT Plug and Play certification, an incremental certification beyond the baseline Azure Certified Device certification, validates Digital Twin Definition Language version 2 (DTDL) and interaction based on your device model. It enables a seamless device-to-cloud integration experience and enables hardware partners to build devices that can seamlessly integrate without the need to write custom code.
Edge Managed certification, an incremental certification beyond the baseline Azure Certified Device certification, focuses on device management standards for Azure connected devices. Today, this certification focuses on Edge runtime compatibility for module deployment and management though it will continue to grow in the future with additional customer manageability needs.
Edge Secured-core certification, an incremental certification beyond the baseline Azure Certified Device certification, is for IoT devices running a full operating system such as Linux or Windows 10 IoT. This IoT validation shows devices meet additional security requirements around device identity, secure boot, operating system hardening, device updates, data protection, and vulnerability disclosures.
