Fastly Features

Worried about slow websites and security threats?

Fastly features offer an integrated suite built on its edge cloud platform to accelerate content delivery and enhance security. Here are the five main Fastly features that power fast, secure digital experiences.

1. Content Delivery Network (CDN)

Is slow content delivery frustrating your users?

Long loading times and high latency can kill user experience. This might even drive potential customers away from your site.

Fastly’s CDN ensures rapid content delivery by caching files globally, delivering content from the closest server.
