DTLS session based is using UDP and is shipping from Sproute Networks for a
many years now.  It scales fantastic in a full mesh fashion too ! They also
have all cloud based multi tenant controller so both API and GUI based mgmt
works like a charm. For endpoints both software and hardware options are
available.

I know I am sounding like a salesmen - but I am using their products for
few years now both privately and commercially and never had any issues.
