A method is provided for automating management of automatic renewal of a public key infrastructure (PKI) certificate issued by a certificate authority (CA) for a subscriber. The method includes steps of causing the subscriber to (i) transmit a first alert to a management entity for initiating renewal of the PKI certificate, and (ii) transmit a certificate signing request (CSR) to a registration authority (RA) for issuance of a renewal certificate. The method further includes steps of (iii) transmitting, from the RA to the CA, the CSR signed by the RA, (iv) receiving, at the RA from the CA, an issued renewal certificate signed by the CA, (v) sending, from the RA to the subscriber, the issued renewal certificate signed by the CA, and (vi) causing the subscriber to transmit a second alert to a management entity indicating renewal of the PKI certificate.
