ClawShield: open-source defense-in-depth firewall for OpenClaw agents

Security proxy using Go + iptables + eBPF kernel monitor for OpenClaw. Three layers: application (prompt injection, PII, secrets scanning), network (egress allowlist), kernel (syscall monitoring). Built after 40K+ exposed instances discovered with CVE-2026-25253.

Product Idea from this Signal

A CLI tool that scans a running OpenClaw instance for every known CVE, exposed endpoint, malicious skill, and token scope violation, then outputs a prioritized remediation checklist

25.3k ▲

OpenClaw accumulated 138+ CVEs in under 5 months, 245,000 instances sit exposed on the public internet, and 1,400+ malicious skills infiltrated ClawHub via the ClawHavoc campaign. Individual developers and small teams have no single tool to check their install against all known threats. NemoClaw requires NVIDIA GPU infrastructure, ClawShield is a network proxy that doesn't scan the instance itself, and SkillFortify only covers skill verification. The gap is a lightweight scanner that checks everything in one pass and tells you exactly what to fix.
