The answer to this is more along the lines of the original target audience of DDS operating private/closed networks. When all your communication happens within a single Navy frigate on dedicated communication wires, security is less problematic. DDS growing beyond its original audience has caused many vendors to start thinking about how to do security. A VPN is one option, but obviously many users want something a bit lighter weight.
