Block Logins with Cloudflare helps protect your WordPress site from brute-force attacks by blocking IPs at the Cloudflare firewall after a configurable number of failed login attempts.
<ul>
<li>Block IPs via Cloudflare after X failed login attempts</li>
<li>Block IPs that generate excessive 404 responses (bots and scanners)</li>
<li>Block IPs attacking via XML-RPC with intelligent detection</li>
<li>Automatic unblocking after a configurable duration</li>
<li>Whitelist IPs to never block or track them (supports IPv6 CIDR ranges)</li>
<li>View and manually unblock blocked IPs from the admin</li>
<li>Block source tracking — see whether each IP was blocked via login, XML-RPC, or 404</li>
<li>Secure settings page with Cloudflare API token validation</li>
<li>Hourly cron job for automatic maintenance</li>
</ul>
<h3>External Services</h3>
This plugin relies on the Cloudflare API to function. It communicates with Cloudflare’s external servers to block IP addresses at the firewall level.
What is the Cloudflare API and what is it used for? 
The Cloudflare API is a RESTful service provided by Cloudflare, Inc. that allows programmatic management of Cloudflare firewall rules. This plugin uses it to automatically block and unblock IP addresses based on failed login attempts, XML-RPC attacks, and 404 scanning activity.
What data is sent and when? 
The plugin sends the following data to Cloudflare’s API servers:
<ol>
<li>
During settings validation (when you save Cloudflare credentials):
<ul>
<li>Your Cloudflare API token (for verification)</li>
<li>Endpoint: <code>https://api.cloudflare.com/client/v4/user/tokens/verify</code></li>
</ul>
</li>
<li>
When blocking an IP (after a threshold is reached):
<ul>
<li>The IP address to be blocked</li>
<li>Your Cloudflare email address and API key/token</li>
<li>Your Cloudflare Zone ID</li>
<li>A note describing the reason for the block</li>
<li>Endpoint: <code>https://api.cloudflare.com/client/v4/zones/{zone_id}/firewall/access_rules/rules</code></li>
</ul>
</li>
</ol>
No personally identifiable information about your WordPress users is transmitted. Only IP addresses are sent to Cloudflare.

BotBlocker Security blocks 99% of automated attacks before WordPress even loads. No bloat, no slowdowns, no monthly fees for core protection.
If your site is hit by login brute force, spam comments, fake Googlebots, content scrapers, or XML-RPC floods, you are not alone: bots generate over 47% of all web traffic. Most security plugins react after WordPress boots, wasting CPU and memory on every bad request. BotBlocker stops them at the door.
<h4>Why site owners switch to BotBlocker</h4>
<ul>
<li>Faster than the competition. Runs on early init through three interception layers, before themes and plugins load. Server load drops during attacks instead of spiking.</li>
<li>Smarter CAPTCHA. 9 modes including Silent Auto-Verify – zero clicks for humans, hard wall for bots. Proprietary CAPTCHAs defeat AI-based solvers that crack reCAPTCHA for $2-3 per 1 000.</li>
<li>Honest free version. Full firewall, all 9 CAPTCHA modes, full 2FA, full logging, full Multisite support. No nag screens, no crippled features.</li>
<li>Privacy-first. No visitor data leaves your server. GDPR and CCPA compliant out of the box.</li>
<li>Works with everything. Cloudflare, WP Rocket, LiteSpeed, WooCommerce, Elementor, multisite, IPv6, PHP 7.4 to 8.5.</li>
</ul>
<h4>🛡️ Core Firewall (Free)</h4>
<ul>
<li>Three-Layer Architecture – intercepts traffic at wp-config.php (before WordPress), MU-plugin phase, and main shield. The first layer blocks known threats without loading WordPress at all, saving 30-100ms and 5-20MB RAM per blocked request.</li>
<li>Web Application Firewall (WAF) with real-time rule updates via the BotBlocker Threat Defense Feed</li>
<li>2 899 User-Agent signatures – largest blacklist among WordPress plugins – covering Scrapy, Selenium, Puppeteer, PhantomJS, curl, wget, Python, Java, Perl, and SQL injection tools</li>
<li>Brute force protection with progressive lockouts – 5 attempts per 15 minutes, escalating bans for repeat offenders</li>
<li>Anti-spam for comments, registration, contact forms – spammers blocked before they connect</li>
<li>XML-RPC and REST API locked down by default with allowlist for trusted services</li>
<li>Fake crawler detection via FCrDNS (dual-direction DNS verification), ASN tokens, and published IP ranges – 95% effective, impossible to spoof without controlling the provider’s DNS zone</li>
<li>LLM / AI crawler management – allow or block GPTBot, ChatGPT-User, ClaudeBot, PerplexityBot, Bytespider via CIDR-verified IP ranges. Trusted crawlers verified, impersonators blocked.</li>
<li>Country, ASN, IP range, User-Agent, Referer blocking rules with instant enforcement</li>
<li>Cloudflare-aware real-IP resolution and origin bypass protection</li>
