The Data Sovereignty Question
Portkey is an excellent AI gateway for organizations comfortable with cloud-based AI traffic processing. For organizations in regulated industries where AI model traffic, prompt data, and compliance telemetry cannot transit third-party infrastructure, SmartFlow's on-premises architecture is the only option that provides true data sovereignty.
The 30-day log retention limit in Portkey's standard offering is also a consideration for industries requiring 6+ year retention under HIPAA or 7+ years under SOX. SmartFlow's customer-controlled logging has no retention limits.
Where Portkey Excels
Portkey has the best developer experience in the AI gateway market, excellent observability tooling, strong prompt management features, and proven SOC2/HIPAA certification. For cloud-native teams without on-premises requirements, Portkey delivers fast time-to-value with minimal configuration.
