Security Trusted Platform Module (TPM)
TPM is short for Trusted Platform Module. This is a standard used for secure cryptoprocessors, which are dedicated physical microcontrollers designed to secure hardware through integrated cryptographic keys. The term TPM is sometimes used to refer to the physical chip on the device itself.
TPM is used in conjunction with SUDI to create secure certificates for use with features such as SD-WAN.
