2021 saw more than 20K vulnerabilities to exploit - the greatest number on record.
API-related traffic represented almost 54% of Cloudflare network traffic in 2021.
Up to 40% of all Internet traffic is bot traffic - and a significant portion is malicious.
94% of desktop and mobile sites use third-party resources.
By making Cloudflare's network your enterprise security perimeter, you gain a modern application security posture. All Cloudflare security, managed from a single console, is delivered from our global edge network of 270 data centers in more than 100 countries for incredible performance, reliability and unlimited scalability.
