Falco
The cloud-native runtime security project.
Overview
Falco, a CNCF project originally created by Sysdig, is the de facto standard for cloud-native runtime security. It taps into kernel system calls to detect and alert on unexpected application behavior, providing real-time threat detection for containers and cloud environments.
✨ Key Features

- Behavioral Activity Monitoring
- Rule-based engine with extensive default rules
- Alerting on suspicious activity
- Extensible with plugins
🎯 Key Differentiators
- Specifically designed for cloud-native environments (containers, Kubernetes)
- Deep kernel-level visibility
- Rich, extensible rule language
Unique Value: Provides a powerful, open-source engine for real-time detection of anomalous behavior in your cloud-native applications.
