MS Header Analyzer

The tool analyzes HTTP response headers to reveal security posture, caching directives, content policies, and infrastructure signals. It accepts either a raw header block or a live URL, parses and normalizes header names, handles multi-value headers, and standardizes values for comparison. Target users include developers integrating APIs, QA engineers validating deployments, security auditors, and performance engineers who need fast, objective visibility without manual review. By focusing on headers rather than content, it scales across services and environments.
For each header, the tool computes a risk signal and provides actionable remediation. It checks for critical controls such as HSTS, Content-Security-Policy, X-Content-Type-Options, and Secure/HttpOnly cookie flags, as well as caching directives and CORS policies. Results include per-header scores, rationale, and concrete steps to fix misconfigurations. An optional bulk mode compares results across environments and highlights regressions.
Distinctive value comes from RFC-aligned parsing, clear per-header guidance, and exportable reports (JSON, CSV, Markdown) suitable for engineering runbooks and security reviews. It supports custom presets, multi-environment baselines, and historical comparisons to track progress over time. Privacy-conscious deployment options let teams run analysis client-side or on trusted infrastructure.
Common use cases include API hardening during CI, security audits, performance tuning of caching headers, and vendor assessments. Typical outputs enable faster remediation, better compliance, and fewer hotfixes after deployment.
