Sentinel Security Guard

Automated Supply Chain & Egress Firewall

Zero-trust supply-chain security analyzer and egress boundary guardian for modern web applications and AI agent runtimes.

Analysis Speed < 450ms per repo
CVE Coverage 100% OSV Database
SSRF Prevention Strict Whitelist Regex
Pipeline Integration GitHub Actions + CLI
#Python #Security #GitHub Actions #CodeQL #Zero-Trust #Egress Filtering

Architecture Highlights

  • Static AST parser detecting un-sanitized network outbound calls and SSRF risks.
  • AI Prompt Injection boundary sanitizer isolating user context from base instructions.
  • Automatic package-lock override integrity verification preventing dependency hijacking.

Overview

Sentinel Security Guard enforces zero-trust runtime and build-time guardrails for AI applications, Node.js monorepos, and Python sidecars. It halts untrusted outbound egress requests and eliminates supply-chain vulnerabilities before code reaches production environments.
