Aperçu
Push IPv4 threat-intelligence indicators from OpenCTI into a Cloudflare Rules List for use in WAF and firewall rules.
Cloudflare Rules Lists are reusable collections of IP addresses that can be referenced from WAF custom rules, firewall rules, and other security configurations across a Cloudflare account.
The integration of Cloudflare with OpenCTI enables the automatic dissemination of IPv4 threat-intelligence indicators and observables into a Cloudflare Rules List. The connector consumes IPv4 indicators from an OpenCTI live stream, maintains an in-memory snapshot, and periodically replaces the contents of a target Cloudflare Rules List (IP kind) using Cloudflare's bulk list-items API documented at https://developers.cloudflare.com/api/resources/rules/subresources/lists/.
