Connected Cache nodes only download and store Microsoft content from provisioned Microsoft and Content Delivery Network (CDN) endpoints, so there are no concerns about the cache storing personal or sensitive data. Connected Cache nodes only download and store Microsoft content from provisioned Microsoft and Content Delivery Network (CDN) endpoints, so there are no concerns about the cache storing personal or sensitive data.
Connected Cache works in tandem with the [Delivery Optimization (DO) client](waas-delivery-optimization.md), a component of Windows Update that manages the downloading of Microsoft content. Regardless of download source, the DO client on each Windows device verifies the authenticity and integrity of downloaded content using its metadata hash, content hash, and signature before installing. This process ensures that the Windows device is protected against man-in-the-middle attacks that attempt to tamper with content while it's in transit.

As you can see in this diagram, Connected Cache nodes currently utilize HTTP to communicate with CDN endpoints and Delivery Optimization clients. There's work planned to support HTTPS communication between CDN endpoints and Delivery Optimization clients in the future.
