In my ongoing obsession for Website Speed (especially WordPress Website speed and SEO implications), I’ve tried many Plugins (e.g. W3 Total Cache and WP Super Cache), CDNs (the mighty AWS CloudFront and MaxCDN), good DNS hosting (notably AWS Route 53 and CloudFlare) and Web Content Optimization services such as CloudFlare and the Google PageSpeed service.
As a by product of my various performance optimization and testing, in addition to fixing hacked WordPress Websites and providing WordPress security consulting, I’ve learnt quite a bit about how hackers and other Web nuisance makers ply their trade. When a client approaches me to improve their WordPress security there is always a cost/benefit equation to consider. In the various analyses there is very rarely any better cost/benefit service or set of tasks available than merely using CloudFlare to handle Website security. Quite simply, CloudFlare offers awesome security at a very low price (or free if you’re happy with a limited set of security … which is adequate for many Sites).
If it weren’t for Cloudflare, all booters would be ddosed into oblivion by their competitors.
Heck, if the DDoS for hire services protect themselves against DDoS attacks by using CloudFlare then CloudFlare must be damn good!
