Gain insight into your digital health by streaming logs from the edge.

Continuous optimization means you need to analyze data and create alerts for parameters such as request-response times, origin failures, and suspicious traffic. These actionable insights will empower you to resolve issues quickly and optimize continuously, which can flow into the logging endpoint of your choice.

High-performance security at scale with fast and easy TLS.

We believe that implementing the highest standard of TLS encryption across your website shouldn’t slow it down. Simplify and automate TLS provisioning across all your domains through our extensive APIs, with the flexibility to use any certificate you’d like. Plus, you can terminate secure TLS connections at the edge, offloading encrypted traffic from your web server for better performance.

Fastly supports scalable security for over a million GitHub Pages

“I would recommend that people use Fastly. GitHub actually plans Fastly and its CDN services into our development and product roadmap. Fastly is a huge part of our toolkit for writing high performance, high scale web apps.”

Jesse Newland, Systems Engineer

How using an edge cloud platform complements a multi-cloud approach

Using an edge cloud network with a multi-cloud approach offers you the opportunity to add a uniform layer on top of your cloud infrastructure, sitting between the core cloud and end-users. This gives your developers a single place to manage the tools to optimize performance while also giving greater visibility over your network. The network edge is a powerful ecosystem for modern app development, offering more agility, control, and security to IT teams.
