EMQX allows you to configure Access Control Lists to authorise access to topics.

See https://github.com/emqx/emqx/wiki/ACL-Design and https://docs.emqx.io/broker/v3/en/config.html#anonymous-authentication-and-acl-files

e.g. an acl.config file with:

{allow, {user, "testuser"}, subscribe, ["a/b/c", "d/e/f/#"]}.
{allow, {user, "admin"}, pubsub, ["a/b/c", "d/e/f/#"]}.
{deny, all}.

will allow the client testuser to subscribe to topics a/b/c and d/e/f/# only, while admin is allowed to publish and subscribe these topics.
