We are reevaluating our content filter products for our macOS devices and hoping to find a solution that could potentially work with both macOS and iOS devices when students are off-campus.
What has worked for schools/districts now that more devices are going home?
We manage around 4,000 iOS devices with a content filter called DrawBridge. It is produced by a company called Compass Foundation, it works well for us. It works through the Proxy PAC URL so you can filter both on premise and remotely. We also use the same content filter on Mac and Windows devices with really good results.
