About Upwind

Upwind ships an eBPF-backed CNAPP that folds CSPM, CWPP, CDR, identity, and API security into one live map of cloud inventory.

It uses runtime evidence to drop most of the theoretical vulnerability noise so teams fix the paths that are reachable in production. The 2026 Agentic Pack adds investigation and validation agents on top of that same runtime fabric.
