With the release of iOS 15 by Apple a new feature has been enabled for paid subscribers of their iCloud storage product called iCloud Private Relay and it's essentially a VPN service for the Safari browser on iOS 15 and macOS Monterey.
We've been monitoring the service throughout the beta of iOS 15 and we've determined that Apple is using three content delivery networks as partners for this feature which we've been able to detect without issue. Today we've enabled this detection on our API which means by default users of iCloud Private Relay will now be detected as VPN's when visiting your sites and services.
We know that since this is baked into iOS 15 and macOS Monterey it may become a popular service amongst your users and so you may not want to block users from accessing your sites and services when they use iCloud Private Relay.
Due to this we've added a new custom rule to the dashboards rule library (Big Business -> Allow iCloud Private Relay) which when enabled will allow these users to bypass being detected as VPN's while keeping other VPN services blocked. We will say that since iCloud Private Relay is a paid service and most Apple users do not pay for iCloud you may not deem it necessary to whitelist the service but we've made the rule available to you just in case.
Thanks for reading and have a great week.
