Foxguard

foxguard Plugin

Security scanner as fast as a linter with post-quantum crypto audit, diff scans, secrets detection, and CycloneDX CBOM export. Tree-sitter based with Semgrep/OpenGrep compatible rules.

Commands

Scanning

• foxguard scan run — Scan the target path for security issues
• foxguard scan diff — Show new findings compared to a target branch or commit
• foxguard scan secrets — Scan for leaked credentials and private keys
• foxguard scan pqc — Post-quantum crypto audit (NSA CNSA 2.0 compliance)

Configuration

• foxguard config init — Install local pre-commit hook

Utility

• foxguard self version — Print foxguard version
• foxguard _ _ — Passthrough to foxguard CLI

Usage Examples

• "Scan the current directory for security issues"
• "Diff scan against main branch to find new issues"
• "Check for leaked secrets in the repo"
• "Run a post-quantum crypto audit"
• "Generate a CycloneDX CBOM for compliance"
• "Scan only modified files"

Installation

curl -fsSL https://foxguard.dev/install.sh | sh

Examples

# Scan the current directory
foxguard scan run .

# Scan and generate SARIF output
foxguard scan run . --format sarif

# Generate a CycloneDX 1.6 CBOM
foxguard scan run . --format cbom

# Scan only modified files
foxguard scan run . --changed

# Include source-to-sink dataflow traces
foxguard scan run . --explain

# Diff scan against main branch
foxguard scan diff main .

# Scan for leaked credentials and private keys
foxguard scan secrets .

# Scan for leaked secrets with SARIF output
foxguard scan secrets . --format sarif

# Post-quantum crypto audit
foxguard scan pqc .

# PQ audit with CBOM output
foxguard scan pqc . --format cbom

# Post findings as PR review comments
foxguard scan run . --github-pr 42

# Install pre-commit hook
foxguard config init

Key Features

• Four scan modes: Full scan, diff scan, secrets scan, post-quantum crypto audit
• Post-quantum crypto audit: Annotates PQ-vulnerable algorithms with NSA CNSA 2.0 migration deadlines
• Diff scanning: Find only new issues compared to a target branch or commit
• Secrets detection: Leaked credentials, API keys, private keys, tokens
• CycloneDX CBOM export: Cryptographic bill of materials for compliance
• Source-to-sink dataflow traces: --explain flag shows how vulnerabilities flow
• PR review integration: Post findings directly as GitHub PR comments
• Pre-commit hook: foxguard init installs a local pre-commit hook
• Tree-sitter based: Accurate parsing across Python, JavaScript/TypeScript, Go, Java, Rust
• Semgrep/OpenGrep compatible: Custom rules via --rules flag
• TUI triage: Run foxguard tui . directly for interactive review, baseline, ignore, severity overrides

Output Formats

• Default — Human-readable terminal output
• SARIF — Static Analysis Results Interchange Format for CI integration
• CBOM — CycloneDX 1.6 Cryptographic Bill of Materials
• JSON — Structured JSON for programmatic consumption

Supported Languages

• Python
• JavaScript / TypeScript
• Go
• Java
• Rust
• TLS configuration files (OpenSSL, nginx, Apache)

Notes

• Post-quantum rules ship for all supported languages plus TLS configs
• Each PQ finding carries the matching CNSA 2.0 deadline (2030 for software signing, 2033 for traditional networking)
• Remediation guidance surfaces ML-KEM-1024 / ML-DSA-87 for NSS workloads and ML-KEM-768 / ML-DSA-65 for commercial use
• The foxguard tui . command opens an interactive TUI and should be run directly, not via supercli
• npx foxguard works without any installation for one-off scans
