What security protocols are folks using to protect SONET/SDH?
At what speeds?
That's rather a surprising choice (ATM product) for an IP network.
Please describe what backbone you are running that uses a FASTLANE?
Hopefully, other folks are securing their PPP or ethernet packets?
By security protocol do you mean encrypting the traffic?
Like what a Fastlane does?http://www.gdc4s.com/Documents/Products/SecureVoiceData/NetworkEncryption/GD-FASTLANE-w.pdf

I'd be surprised if a civilian org could buy a fastlane device,..
maybe they moved out of the gov't only world though since the last
time I saw one? It does claim to do oc-48 rate sonet though.

claims 40gbps... I don't know that a purely civilian org can purchase
these though, nor the kg-75, despite these being on the GD site.

And at $189,950 MSRP, obviously every ISP is dashing out the door
for a pair for each and every long haul fiber link. 
Hard to see the IETF multi-vendor interoperability specifications. It
does mention SNMPv3, unlike all their other products which use a
proprietary management scheme. Also HTTP, although no mention of its
purpose.
At least the FASTLANE mentioned above specifies FIREFLY -- the mere
rumor of which was our basis for naming Photuris [RFC2522].

But I don't see where you mention that Google is actually using
these to secure your fiber?
Not HTTPS? 
cheaper by the dozen?
