That's great.

Now we need to get an enterprise grade switch - doubt Cisco would add macsec into SOHO gear. Along with enterprise grade intercoms, cameras, doorbells...

And beloved by many Unifi is out of question - they still can't bake IPv6 support.

So looks like it's feasible but the cost wouldn't be good.

i well familiar with macsec. we use it between datacenters and for aws directlink. it de-facto standard for this kind of stuff. i even worked on hardware that provided macsec support

a couple of years ago I tried to use it inside datacenter during fedramp implementation. it crashed and burned for a couple of reasons:

- linux wpa_supplicant was crashing during session establishment

- switch had a limit on number of macsec session per port
