Why Container Security Matters Containers run everywhere — from CI pipelines to production Kubernetes clusters. But their ephemeral nature makes them a blind spot for traditional security tools. A container can spin up, execute malicious code, exfiltrate data, and terminate in under 30 seconds — long before any human analyst notices.

I set out to build Zero-Day Guardian (ZDG) , a system that detects container threats in real time, responds automatically, and preserves forensic evidence before a container self-destructs. The goal was to close the gap between detection and response from minutes to milliseconds.

The Current Landscape Existing container security solutions fall into two categories: image scanners that check for known CVEs before deployment, and runtime agents that monitor container behavior after launch. Image scanners miss zero-day exploits and supply chain attacks that inject malicious code post-build. Most runtime agents operate in userspace and are blind to kernel-level breakouts.
