As answered by people managing SiteScanAPI and Detectify.
SiteScanAPI's answer
SiteScanAPI bridges the gap between manual header checkers and complex, heavy vulnerability scanners. It is 100% passive, zero-auth, and runs entirely on global edge infrastructure (Cloudflare Workers) to deliver deterministic perimeter security audits in under 250 milliseconds.
Unlike traditional tools that only look at a handful of legacy HTTP headers, SiteScanAPI inspects the complete perimeter: • Comprehensive Headers: Strict-Transport-Security with preload validation, Content-Security-Policy (CSP), X-Frame-Options, and Referrer-Policy. • Next-Gen Origin Isolation: Verification of COOP, COEP, and CORP browser sandboxing boundaries. • DNS-over-HTTPS (DoH) Security: Real-time email authentication audits for RFC-compliant SPF and DMARC records. • Information Leak Detection: Stripping server banners (Server, X-Powered-By). • RFC 9116 Compliance: Verification of /.well-known/security.txt disclosure files. • Automated Remediation: Generates instant copy-paste configuration directives for Nginx, Apache, Caddy, Cloudflare, and modern frameworks.
SiteScanAPI's answer
Most competing security scanners suffer from three major drawbacks: they are slow (waiting in multi-second queues), lack a developer REST API, or require cumbersome account signups with paywalled API keys.
Developers and security teams choose SiteScanAPI because: 1. Zero-Auth REST API: You can query https://sitescanapi.com/api/scan?url=yourdomain.com right from curl, CI/CD pipelines, or monitoring bots without API keys, tokens, or sign-up walls. 2. Edge Performance (<250ms): Audits complete almost instantly from the closest global edge node. 3. Non-Intrusive & Zero Downtime Risk: 100% passive HTTP and DNS interrogation ensures your firewalls aren't tripped and production uptime is never jeopardized. 4. Ready-to-Paste Fixes: Instead of just reporting warnings, SiteScanAPI produces exact server configuration snippets so you can fix failing grades in minutes.
SiteScanAPI's answer
The primary audience consists of: • Web Developers & Full-Stack Engineers: Who want to verify that production deployments enforce modern defensive headers like HSTS and CSP. • DevOps & DevSecOps Engineers: Who need a lightweight, zero-key REST API to gate release builds in GitHub Actions, GitLab CI, or deployment webhooks. • Security Analysts & Penetration Testers: Looking for instant, passive reconnaissance on target domains before conducting in-depth assessments. • Digital Agencies & Webmasters: Auditing client web applications for SSL/TLS, email spoofing (SPF/DMARC), and vulnerability disclosure compliance.
SiteScanAPI's answer
SiteScanAPI is engineered for ultra-low latency, resilience, and minimal client overhead using: • Cloudflare Workers / Edge Runtime: Powers both the globally distributed scanning engine and the sub-250ms REST API. • Astro (v7): Delivers zero-JS editorial performance, rapid static rendering, and server-side edge rendering. • TypeScript: Type-safe RFC evaluation logic and deterministic scoring algorithms. • React 19: Powers the real-time interactive Scanner Dashboard island. • Tailwind CSS (v4): Custom editorial design system engineered for visual clarity and accessibility. • DNS-over-HTTPS (DoH): Cryptographic DNS queries for real-time SPF and DMARC email security validation.
SiteScanAPI's answer
Over 60% of production websites fail basic defensive security audits—not because engineering teams don't care about security, but because perimeter configurations are fragmented across dozens of RFCs, W3C drafts, and server syntaxes.
Existing diagnostic tools were built a decade ago: they were clunky, loaded with ads, slow to respond, and lacked a simple API that could easily fail a build in modern CI/CD pipelines.
SiteScanAPI was built with a clear mission: to democratize perimeter web security. By leveraging modern edge computing, we made defensive security audits instant, deterministic, developer-first, and completely accessible to every engineer without friction or cost barriers.
