Security in the fast lane

Our vast global network spanning 275 cities is one of the fastest on the planet. In fact, we can reach 95% of the world’s population within approximately 50 ms.

That means our single-pass security inspection happens at the data center closest to its source, so security never comes with a performance tradeoff.

Cloudflare WAF was so easy and intuitive to use. It took our engineers almost no time to get up to speed. We’ve now expanded our usage of Cloudflare’s suite of products. Integrating with any Cloudflare solution has been just so smooth and painless
