System Documentation

What problem does it solve?

It helps identify weaknesses in an organization’s web and email security posture by reviewing HTTP security headers, Content Security Policy behavior, HSTS configuration, DNS-based email authentication records, and common security-discovery endpoints.

Core Features & Use Cases

  • HTTP security header assessment: Detects presence and strength of key headers like HSTS, CSP, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to highlight missing protections and risky configurations.
  • Content Security Policy analysis: Evaluates CSP directives for unsafe allowances (such as unsafe-inline or unsafe-eval), derives third-party domains, and estimates overall CSP strength.
  • Email security DNS record review: Checks SPF, DKIM, and DMARC values to assess spoofing resistance and enforcement/reporting posture.
  • Security discovery file validation: Verifies availability and content signals of security.txt (and related paths) to ensure security contact and operational expectations are present.

Quick Start

Ask it to analyze your Phase 2 HTTP, DNS, HTML, and repository signals for missing or weak security headers, risky CSP directives, weak email authentication records, and absent security-discovery files.
