Stop Brute Force Attacks at the Edge
Offload server load by synchronizing local WP Cerber IP lockout events directly to your Cloudflare Account IP Lists. Block malicious bots at the edge before they consume a single byte of your origin server's bandwidth.
Extending WP Cerber to the Edge
WP Cerber is a world-class detection engine, but it is bounded by your server's hardware limits. Our plugin bridges WP Cerber's local lockout intelligence with Cloudflare's edge network to form an impenetrable barrier.
WP Cerber Detects & Locks
A botnet attempts brute-force logins. WP Cerber Security detects the malicious activity and successfully locks out the IP address locally.
The Plugin Bridges the Event
The moment WP Cerber locks the IP, our plugin intercepts the event, sanitizes the IP address, and prepares the API payload.
Immediate Edge Sync
The plugin securely transmits the IP to your Cloudflare IP List. The block is applied across Cloudflare’s global edge locations within milliseconds.
Server Load Dropped to Zero
Subsequent requests from that blocked IP are discarded at the CDN level. They never reach your WordPress host, saving CPU and database resources.
Why Cerber Lockout Cloudflare Sync?
Zero-Latency Blocking
Drop malicious traffic on Cloudflare's network, keeping your server CPU and memory completely free from repeat offenders.
Dual-Stack Validation
Complete support for both IPv4 and IPv6 addresses, keeping all brute force and network-level vectors fully covered.
Intelligent Caching
Local database transients cache lockout states to prevent duplicate API requests and avoid Cloudflare rate-limiting.
Smart Fallback API
Resolves credentials dynamically from environmental PHP constants or existing configurations in the official Cloudflare plugin.
Rate-Limited Warnings
Get critical status alerts sent straight to your inbox. Features smart rate-limiting (1 warning per hour) to avoid inbox spam.
Admin Command Center
Run secure connection checks, execute manual lockout syncs, and flush caches directly from your WordPress Settings screen.
