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/webhookwith a missing authorization header
- Block all requests to
/wp-admin
- Challenge all traffic to
/checkoutthat doesn't come from the US
Generate your first rule or learn more in the documentation.
