What this plugin can do for you
One-click WordPress-optimized settings
The easiest way to setup Cloudflare for your WordPress site.
Web application firewall (WAF) rulesets
Available on all of Cloudflare’s paid plans, the WAF has built-in rulesets, including rules that mitigate WordPress specific threats and vulnerabilities. These security rules are always kept up-to-date, once the WAF is enabled, you can rest easy knowing your site is protected from even the latest threats.

Occurs when you change the appearance of your website. This means that you can focus on your website, while we ensure that the latest content is always available to your visitors.
Automatic individual URL cache purge on page/post/custom post type edits
Cloudflare’s plugin for WordPress automatically refreshes the Cloudflare cache of each post/page/custom post type when you update the content.
Header rewrite to prevent a redirect loop when Cloudflare’s Universal SSL is enabled
