Re-architecting Vantage's systems so security is designed in rather than bolted on: the eight-tile architecture board — requirements traced to real drivers, trust boundaries drawn with web and database split, identity with SSO built in and services that authenticate, data kept as the last four card digits with keys apart from credentials, a network that takes IoT off the payments segment and gates egress, resilience with no single data centre and tested restores, secure defaults that deny first, and a review with a threat model and an ADR; beside it, the redesigned checkout drawn as four tiers — edge, web, app services and data — separated by explicit trust boundaries, with the key store held apart.
