Docker Firewall Auditor and Network Security Scanner
C6/10May 5, 2026
WhatA CLI and SaaS tool that scans running Docker and Compose environments to detect ports accidentally exposed past host firewalls, misconfigured networks, and leaked secrets, then generates fix-it patches.
SignalEven experienced Docker users are surprised and burned by Docker's port-publishing behavior silently bypassing iptables firewall rules, and the discussion reveals this remains a common footgun that catches people in production.
Why NowRising container-targeted attacks, new compliance requirements like SOC 2 for startups, and the proliferation of self-hosted apps via Compose have made Docker network misconfigurations a growing attack surface.
MarketDevOps teams and solo developers running self-hosted infrastructure; overlaps with Trivy and Dockle but neither specifically audits runtime network exposure or firewall bypass; potential acqui-hire target for Docker Inc or Snyk.
MoatA continuously updated database of Docker networking edge cases and distro-specific firewall interactions becomes a proprietary knowledge base that deepens with each scan.
