According to certain embodiments, a delivery manager comprises an interface and processing circuitry. The interface is configured to receive a certificate that a DNS associates with a DNS name of a first endpoint. The processing circuitry is configured to distribute the certificate to a second endpoint. The second endpoint is configured to store the certificate in a local memory of the second endpoint and, in response to a future determination to establish a connection with the first endpoint, use the certificate from the local memory of the second endpoint to establish transport layer security (TLS) for the connection.
