 IoT Edge can interface with an [Enrollment over Secure Transport (EST) server](https://wikipedia.org/wiki/Enrollment_over_Secure_Transport) for automatic certificate issuance and renewal. Using EST is recommended for production as it replaces the need for manual certificate management, which can be risky and error-prone. It can be configured globally and overridden for each certificate type.
 
-In this scenario, the bootstrap certificate and private key are expected to be long-lived and potentially installed on the device during manufacturing.
