The collective knowledge of 5,500,000 websites powers a new kind of security.
Security
Online threats range from nuisances like comment spam and excessive bot crawling to malicious attacks like SQL injection and denial of service (DOS) attacks. Cloudflare provides protection against all of these types of threats and more to keep your website safe.

Thanks to the great support we received from the Cloudflare team, especially during our peak weeks in May, we’ve felt more secure that the sites would keep running smooth regardless of amounts of traffic—and they have.
