What paid plan can I activate with CloudFlare in order for me to put security threat behind me.
What is your domain & what security threats are you having to deal with?
Please, what other security threats can be taking against a WordPress site?
Wordpress has a plugin for Content-Security-Policy headers. Use it. But know what these headers do first. Honestly I upgraded to the Pro Plan earlier and went through every single WAF rule and I’m impressed with the majority of the default settings. Get it, & turn on the WAF as soon as you do. Stick with defaults. You’ll get 20 each manual Firewall Rules and Page Rules as well. Use them judiciously.
