About Scanner

Our Mission

Scanner is a public recon intelligence platform designed to help bug hunters, security researchers, and developers understand the technology landscape of websites through passive analysis. We believe that transparency in public-facing configurations helps organizations improve their security posture.

What We Do

  • Detect technologies, frameworks, and services used by websites through publicly visible indicators
  • Analyze publicly accessible JavaScript files for exposed endpoints and configurations
  • Evaluate security headers and provide scoring based on best practices
  • Check for commonly exposed public files that may indicate misconfigurations
  • Detect exposed secrets, API keys, and credentials in JavaScript bundles

Ethical Standards

Scanner operates exclusively through passive reconnaissance. We adhere strictly to ethical standards:

  • Only publicly accessible data is collected
  • No brute forcing, authentication bypass, or active exploitation
  • No destructive scanning or denial of service
  • Rate-limited requests with proper identification
  • Respect for robots.txt and site policies
