A payment gateway connects your checkout to a single acquirer and passes the transaction through. A payment orchestration layer sits above multiple gateways and acquirers, deciding in real time which route each transaction should take. Hub is Hellgate's orchestration fabric: it applies routing rules, handles failover, integrates fraud scoring from Specter, and gives you one API across all your providers.

The difference is intelligence and portability: a gateway is a pipe; orchestration is the logic that controls which pipe to use, and when to switch.
