Why This Matters

foxguard introduces a revolutionary security scanner built in Rust that performs instant local code analysis, enabling developers to run security checks in real-time during development. Its speed and integration capabilities make security practices more accessible and immediate, reducing the reliance on slower CI-based scans. This advancement has the potential to significantly improve security hygiene across the software development lifecycle.

Key Takeaways

foxguard

Sub-second local security scanning for real codebases.

100+ built-in rules · 10 languages · single Rust binary · Semgrep-compatible YAML bridge

foxguard.dev · npm · crates.io

A PwnKit Labs product.

Security scanners are slow. 10 seconds, 30 seconds, sometimes a minute. So developers don't run them locally — they get pushed to CI, findings pile up in PRs, and nobody looks at them.

foxguard fixes this by being fast enough that you never notice it's there. Same scan, 0.03 seconds instead of 10. You can run it on every save, every commit, every push. Security feedback becomes instant.
