Hi Dusty,

Full disclosure: I work for VMware (we have a SD-WAN offering) but I’ll
keep it agnostic—

(tl;dr: talk to your friendly vendor SE.)

What sort of collateral would you look for, to give warm fuzzies, if you
were evaluating a traditional WAN routing platform?

You should be able to find security whitepapers and other technical
documents that describe management and data plane security, use of
crypto/PKI etc.

Vendors targeting enterprise customers should be putting their products
through security evaluation frameworks such as Common Criteria — look for
certification, in-flight or completed, against the Network Device
collaborative Protection Profile (NDcPP) plus optional modules like VPN.
Crypto libraries may be FIPS 140-2 [US centric] certified.

For vendors offering things as-a-service, certifications and statements of
conformance against other regulatory frameworks should be applicable (SOC,
FedRAMP [again US centric], IRAP etc. may exist).
