Aegis - PHP Security Inspector

Aegis is a lightweight VS Code extension designed to analyze PHP source code for critical security vulnerabilities in real-time, such as SQL Injection and AI Prompt Injection.

Features

• Real-time Static Analysis: Scans your PHP files instantly upon saving or modifying code.
• SQL Injection Detection: Spots unsafe string concatenations inside raw SQL queries (SELECT, INSERT, UPDATE, DELETE).
• Prompt Injection Defense: Detects potentially vulnerable LLM prompt compositions paired with unsanitized user inputs ($_GET, $_POST).
• One-Click Quick Fixes (Code Actions): Press Ctrl + . on any highlighted warning to automatically secure your queries with PDO Prepared Statements or sanitize prompt inputs using htmlspecialchars.
