If you are packaging your IoT applications as snaps or containers, you are aware of the benefits of bundling an application with its dependencies. Publishing snaps across different operating system versions and even distributions is much easier than maintaining package dependencies. Automated IoT software updates make managing fleets of devices more efficient.

A validation set is a secure policy (assertion) that is signed by your brand and distributed by your dedicated Snap Store. With validation sets you can specify which snaps are required, permitted or forbidden to be installed together on a device. Optionally, specific snap revisions can be set too.
