Very much a cynic here.
I’ve been told several times by several vendors how I should go to sdwan (over the current MPLS) because that’s what everyone is doing. I can usually finish them in one or two questions.
What about QoS, can you guarantee that?
Yes? How can you guarantee QoS over a public internet connection?
A few confused/concerned looks around the room.
Why do you need QoS is usually the next question.
I’m all for progress and SD everything, but it needs to be an improvement on what I have, not a step backwards and having my configured reliant on something outside my network.
The only other thing that bugs me about meraki (this may have changed) is you spend money on hardware, then you pay a subscription. If you stop paying the subscription, that hardware stops working, whilst the old 800 series keeps chugging away albeit without updates if you stop paying maintenance. I see this as a risk, if someone is late paying a bill, someone misses a remittance email, someone ticks the wrong box, the network is gone. Sure it can be rectified, but at what cost to lost productivity?
SDWan has its place but it isn’t an improvement on MPLS imho.

>>> 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).
