Choosing a 3DS Server: Where Five Vendors Sit in the Chain and What Each Actually Covers
"Which 3DS Server should we pick" is an imprecise question, because 3DS is a chain — merchants usually touch only one link, while the other two are decided by card networks and issuers. Placing the five vendors back on the chain changes the question from "who is stronger" to "which link are you on, are you buying compliance or conversion, and do you have local deployment requirements". This article locates first and compares second, then gives four selection dimensions that actually matter and a go-live checklist.
