About Upwind Security
Upwind Security sells a cloud and AI security platform. It combines agentless scanning with runtime sensors so security, developer and DevOps teams can view cloud and AI infrastructure in one operating picture, remediate what matters and stop attacks as they happen. The platform covers live inventory, exposure prioritisation and real-time protection. The company says its approach links code context to production in real time. It refreshes inventory every 30 seconds, claims a 93% reduction in noise and detects attacks within 15 seconds. It sells to enterprises, and its customers include software, SaaS and security firms. Upwind was founded by the team behind Spot.io.
