Create Vercel Firewall rules with natural language

Vercel Firewall now lets you create WAF custom rules using natural language. Describe the behavior you need and the dashboard will generate the rule.

Visit the firewall custom rules page to try creating a rate-limiting rule:

Or use the Vercel CLI:

WAF custom rules let you control traffic to your site by logging, blocking, challenging, rate limiting, or redirecting requests based on conditions like IP address, path, country, user agent, and more.

For example, you can: Log all requests to /api/webhook

with a missing authorization header

Block all requests to /wp-admin

Challenge all traffic to /checkout

that doesn't come from the US

Generate your first rule or learn more in the documentation.
