Architecture

Core security products (Strata NGFW, VM-Series, CN-Series) and services (WildFire, Prisma Access, GlobalProtect) run a proprietary PAN-OS/SP3 single-pass parallel processing architecture that is deployed across on-prem appliances and major public clouds, with cloud-delivered security services and management layers operating on GCP and other hyperscalers.[3][4][7] Data and telemetry are stored in a mix of cloud-native databases and proprietary stores to support threat intelligence, logging, and analytics.
