DEC used to make one (the DESNC), I don't remember the Xerox product.
Cylink used to make one, and may even still (as Safe-Net).
FWIW, IEEE has working group 802.1ae doing Ethernet MAC layer encryption.
But then, they had 802.10 (only implementation I know of was the DESNC) for
many years before retiring it.
The market for these kinds of devices has been notoriously small. May I ask
what your use case is?
Thanks,
