1. A gateway device, comprising:
a hardware computing platform; and
a secure domain name system (DNS) engine comprising circuitry and stored instructions to-program the circuitry, the secure DNS engine to:
communicatively couple to an endpoint via a local network;
begin a secure DNS transaction with the endpoint;
determine whether the endpoint supports delegated credentials;
after determining that the endpoint supports delegated credentials, establish a secure DNS session with the endpoint using a delegated credential; and
determine that the endpoint does not support delegated credentials, and to establish a secure DNS session with the endpoint using keyless SSL.
