Web Headers
CSP/HSTS/XFO/CORS misconfig across Next.js, Vercel, Netlify, nginx, Apache, Caddy and server source in any language.
One of 122 modules in the GateTest scan suite. Catches the issue before it reaches code review, and on paid tiers opens a pull request with the fix already written.
CSP missing — defaults to inline-everything
Why we catch it
Surfacing the user-visible problems static analysis usually pretends don't exist.
The Web Headers module sits in this category alongside 6 related modules. Together they form one of the layers of a GateTest scan — checks fire in parallel, findings cluster by root cause, and on paid tiers the AI auto-fix loop reads each finding, writes the fix, validates against the scanner, and opens a PR.
How GateTest covers web headers
- Runs on every Full scan and above. Full ($99), Scan + Fix ($199) and Forensic ($399) — every repository tier except Quick ($29), which runs only 4 modules. It also runs in the live-URL scanners — the website scan ($29 full report) and the WordPress health check ($19). No additional configuration.
- Free CLI.
npm i -g @gatetest/cli && gatetest --module webHeadersagainst any local repo. No paywall on the scanning itself. - AI auto-fix PR. Scan + Fix tier opens a pull request with the fix, a regression test, and a pair-review by a second AI reviewer. Forensic Scan tier adds per-finding diagnosis and cross-finding attack-chain correlation.
- Honest confidence rating. Findings come with high / medium / low confidence so noisy patterns don't block the gate. The confidence-calibrator trainer reads customer suppressions and tightens rules over time.
