CodeGuard: Open Source AI Security Scanner for Developers...

The Problem

95% of security breaches are caused by vulnerabilities that were already in the code.

Not sophisticated zero-days. Not nation-state attacks. Just overlooked mistakes — SQL injection, hardcoded credentials, insecure API calls, weak input validation — sitting in codebases, waiting to be exploited.

Most developers write code fast. Security reviews happen slow, if at all. Enterprise security tools cost $50K/year. And most teams don't have a dedicated SecOps engineer.

CodeGuard fixes that.

What is CodeGuard?

CodeGuard is an open source, AI-powered security scanner that analyzes your code for vulnerabilities instantly — no setup, no config, no enterprise contract required.

Paste your code or upload a file. Get an immediate security analysis with a severity score, full issue breakdown, real CVE mappings, and actionable fixes.

Features

Core Scanning

  • Detects 30+ vulnerability types — SQL injection, XSS, RCE, SSRF, hardcoded secrets, path traversal, and more
  • Maps findings to real CVEs from NIST NVD
  • Plain-English explanations + exact fix recommendations

Red Team Simulation

  • Simulate real attacker behavior against your code
  • Choose from 8 real threat actor profiles: APT28, Lazarus Group, FIN7, and more
  • See your vulnerabilities through the eyes of an actual adversary

GitHub PR Integration

  • Auto-scans pull requests and posts findings as PR comments
  • Catches issues before they merge into main

Policy Engine

  • Enforce OWASP Top 10, PCI DSS, HIPAA, SOC 2 compliance rules
  • Custom policy creation for your team standards

Monitoring & Alerts

  • Real-time deployment monitoring
  • Instant alerts when new vulnerabilities are detected

Who It Is For

  • Solo developers who want security built into their workflow
  • Startup CTOs who need compliance without a full SecOps team
  • Dev agencies shipping client code
  • SecOps engineers who want AI-assisted threat analysis

Open Source

CodeGuard is fully open source. Fork it, self-host it, contribute to it.
