Show HN: Protection Against Zero-Day Cyber Attacks

Most security approaches I see in production environments focus on:

Scanning for CVEs Hardening configurations Aggregating logs

All useful — but they don’t actually stop exploitation once it starts.

In reality:

Not every CVE gets patched immediately Legacy systems stick around Zero-days happen

When exploitation succeeds, the real damage usually comes from runtime behavior:

A process spawning a shell Unexpected outbound connections Secret access Container escape attempts

I’ve been experimenting with a lightweight runtime enforcement layer for Linux that focuses purely on detecting and stopping high-risk behavior in real time — regardless of whether the underlying CVE is known or patched.

Would love input from folks running Linux/Kubernetes at scale:

Is runtime prevention something you rely on?

Where do existing tools fall short?

What would make this genuinely useful vs just more noise?
