Upwind Security offers a cloud security platform that protects cloud infrastructure, workloads, applications, and APIs by using runtime data to provide real-time visibility and threat detection. It delivers a centralized runtime fabric that maps network and application topology, correlates signals from sensors, logs and APIs, and helps teams reduce alert noise and focus on risks that matter most. The platform combines capabilities for posture management, vulnerability and identity security, container and serverless protection, and cloud detection and response within a single environment. Upwind also includes tools for infrastructure-as-code security and runtime-native analysis, allowing security and development teams to prioritize fixes with contextual insight. Its approach aims to connect build-time and runtime intelligence for comprehensive cloud risk assessment and mitigation.
