Security header audit
Security headers checker for AI-built pages that shipped without CSP.
AI builders rarely configure security headers. Your launch page is missing CSP, HSTS, and X-Frame-Options — and you don't know it. This checker audits headers, explains what's missing, and gives you a copy-paste fix for your framework.

Before launch Practical checklist
Manual checks founders should run before traffic.
This page is the deeper founder checklist. The scanner covers visible public-page signals; backend, auth, payments, and database risks still need human review.
Capture enough evidence that a founder, client, or developer knows exactly what needs to change.
Turn the finding into a specific remediation step instead of a vague compliance note.

Common issues
What polished launches still miss.
For developers and founders launching AI-built apps on Vercel, Netlify, or Cloudflare, these are the gaps that make a launch feel risky once real visitors, clients, or paid traffic arrive.
No CSP means no script control
Without CSP, any injected script can run on your page — XSS, malicious ads, or compromised dependencies.
Missing HSTS exposes users to downgrade attacks
Without HSTS, an attacker can force HTTP connections and intercept traffic before the redirect to HTTPS.
No X-Frame-Options means clickjacking is possible
Your page can be embedded in an invisible iframe and used to trick users on other sites.
Deep dive
What developers and founders launching AI-built apps on Vercel, Netlify, or Cloudflare need to know before they ship.
Most AI-built pages ship with zero security headers. No CSP. No HSTS. No X-Frame-Options. This is a missing security layer against XSS, clickjacking, MIME sniffing, and downgrade attacks. Lighthouse flags this as a best-practice violation.
Content Security Policy controls which scripts, styles, images, connections are allowed. Without CSP, any injected script can run — from compromised CDN, malicious ad, or supply chain attack. A starter CSP takes 5 minutes to deploy.
HTTP Strict Transport Security forces HTTPS. Without HSTS, an attacker on shared Wi-Fi intercepts the initial HTTP request. Google uses HSTS as a ranking signal and recommends preloading for production domains.
Next.js: next.config.js headers(). Netlify: _headers or netlify.toml. Vercel: vercel.json headers. Cloudflare: Transform Rules or Workers. TrustDebt's AI prompt includes the right config for your framework.
FAQ
Fast answers before you scan.
Yes. Google uses HTTPS and security posture as ranking signals. Pages with HSTS and CSP score higher on Lighthouse security audits, which correlates with better rankings.
It can if not tested. Start with Content-Security-Policy-Report-Only header to monitor violations without blocking. TrustDebt's fix prompt includes a safe starter CSP.
At minimum: CSP, HSTS (with preload), X-Frame-Options (or frame-ancestors in CSP), X-Content-Type-Options: nosniff, and Referrer-Policy. TrustDebt checks all of these.
