I've got MACSec deployed for exactly one customer as a point solution. It works once it's in, but the documentation, vendor or otherwise, and choice of suitable equipment were fairly sparse. I certainly wouldn't want to offer it at scale.
Encrypted network conversations with customers, I always try to be very clear about what they're trying to protect against, and make them think properly about trust boundaries. Sure, I can slap a managed CPE on site if I don't already have one and provide overlay encryption - but that doesn't stop a rogue engineer on my side from capturing data before it's encrypted. If what you're concerned about is fibre taps, or security flaws in the MPLS traffic-segregation model or implementation, that helps. If you don't want to trust me as a service provider not to sniff your traffic in the middle, having me encrypt it at the edge really doesn't help - you need to encrypt it yourself, or have a different third-party that you do trust do the encryption.
Some people get it, some people are just trying to fill auditor check-boxes ;)
Agreed. There was a time when the use-case for MACSec was to move banks away from running their own DWDM/FC networks, and letting operators do it. I'm yet to find a bank willing to do this. Maybe I'm not paying enough attention. Mark.
