Automatic Failover

High Resiliency

Even our protection has protection. Origin Shield uses advanced load balancing to equally distribute load and provide dynamic failover. If there are network connectivity issues, requests are automatically rerouted to another edge location.

Full Network Deployment

Global Optimization

Origins are all around the world, so our Origin Shield is too. Rather than a separate network, our Origin Shield runs in all global StackPath PoPs, automatically picking which locations to use for your shield in order to choose the most direct path to your origin and optimize bandwidth usage.

No Additional Cost

Always Included

Premium performance doesn't come at a premium. Origin Shield is available with every CDN package at no additional charge. At StackPath, we protect you from threats and from poor performance.

01 How it works

How it works

Whether you provision fresh content regularly or have large files that require the occasional cache purge, Origin Shield lets you handle request spikes gracefully.

With a traditional CDN configuration, if you reset your cache or publish new content on your origin, every request for content from every edge location gets sent to your origin. This can quickly overload it.
But with Origin Shield, multiple edge requests for uncached content get sent to the Origin Shield, where they are aggregated into a single origin request. And then the content is cached at the shield and further distributed to the requesting edge locations.
