What problem does it solve?

Harden Vercel deployments for Next.js projects by inserting robust security headers, per-request CSP, bot protection, and deployment safeguards, reducing attack surface and configuration drift.

Core Features & Use Cases

  • Static headers in next.config.ts to harden baseline security without CSP because CSP is applied per-request.
  • Per-request CSP and bot protection in proxy.ts to mitigate automated abuse while maintaining Next.js functionality.
  • Dashboard-oriented verification and reference-guidance steps to ensure compliant deployments across plan levels, including Pro features when enabled.

Quick Start

Audit and apply edge security headers, CSP, and bot protection to your Vercel-hosted Next.js project.

FAQPage Schema
How do I add security headers and CSP to a Next.js project deployed on Vercel?

To harden Vercel deployments, apply static security headers in next.config.ts and configure per-request CSP rules in proxy.ts to mitigate automated abuse while maintaining Next.js functionality.

What's the best way to protect a Vercel-hosted Next.js app from bots?

Implementing bot protection for Vercel deployments involves adding honeypot paths and per-request rules in proxy.ts, reducing the attack surface from automated abuse without breaking core Next.js features.

Why apply CSP per-request instead of using static headers in next.config.ts?

Static headers in next.config.ts harden baseline security without CSP, so per-request CSP is applied in proxy.ts to mitigate automated abuse while maintaining Next.js functionality.

Does this Vercel deployment hardening process work across different plan levels?

The hardening process includes a dashboard-style checklist for verification and reference guidance to ensure compliant deployments across plan levels, covering Pro features when enabled on your Vercel account.

How do I verify that security headers and CSP rules are properly applied to my Vercel deployment?

Verification steps are provided alongside code-level changes to next.config.ts, proxy.ts, and robots.txt, offering a dashboard-oriented checklist to ensure compliant security configurations across Vercel plan levels.
