Falco is a tool specifically designed for runtime security monitoring of containers. It provides a way to detect unexpected behavior and vulnerabilities in your containerized applications by monitoring system calls and applying security policies. Falco leverages Kubernetes and Docker events to analyze the behavior of applications in real-time, making it particularly effective in identifying potential threats in containerized environments.

Docker, while an integral part of containerization, is primarily focused on creating and managing containers rather than securing them at runtime. Kubernetes is a platform for orchestrating container deployments and scaling but does not provide built-in capabilities for runtime security monitoring. OpenShift, though it adds additional features on top of Kubernetes, is also not dedicated to runtime security in the same way that Falco is. Thus, Falco stands out as the correct choice for specifically addressing container runtime security.
