Cloudflare has saved my business from over one million attacks since i started using it. It has also saved me a whole lot of bandwidth. Cloudflare is super cool.

It served me well for a very long period, but it never mitigated any of my DDoS attacks. It did helped me when managing DNS was a pain in the ass. BUt eventually I found out that it was slowing my website. Since I moved away from it and got separate services to do what CF used to (DNS, protection, analytics), I got way better services and faster sites.

Pointing my site to Cloudflare is one of the very first things I do while developing a self-hosted site or when taking over an existing site that either suffers on the performance or the security. This is a classic scenario to face while developing a Wordpress site, the client shows up with a slow and unsafe site, using Cloudflare in this cases is a life and time-saver. With a few clicks, you can cache, activate SSL on your site (bringing customers to trust back) and use their CDN that rocks, especially for Javascript. The DNS changes are instantaneous, making server migration a breeze. The protection against DDOS is vital for high-traffic sites, your IP will be hidden as well and your precious server resources will be safe as well. If everything else fails just switch "I am under attack" mode. Cloudflare is now a must have tool for virtually every site I develop.

I'm using Cloudflare for years and never faced any significant issue. I'm overall happy with their product and services.

Atualmente utilizo o cloudflare em todos os sites próprios e também nos sites dos clientes do serviço de hospedagem de sites. Além de melhorar a segurança e a velocidade do acesso ao todos os sites também foi possível economizar no tráfego de cada site uma vez que o cloudflare faz cache da parte estática do conteúdo.
