Announcing Firewall Rules

Cloudflare has launched a new feature called Firewall Rules, which provides customers with fine-grained control over their incoming requests. This feature is designed to help keep applications safe by allowing users to create more complex and flexible firewall rules that can match multiple attributes such as IP address and user-agent. The Firewall Rules engine consists of two components: matching and action. Matching allows users to define filters based on various properties of the HTTP request, while action determines what Cloudflare should do when a filter is matched. This feature also introduces pattern matching using Regular Expressions directly through the dashboard and API.
