I know we can trigger this from Azure Monitor or use a Logic App, but it feels like there should be a way to do an event subscription for a more performant experience for the end user. I just can't find it now :(

@merill @paulsanders @crh @JefTek It looks like they are doing MDM enrollment, and if that's an option, we can use device enrollment restrictions with an access package

There's no built in feature, but the user enrollment would fail, and then we could automate a process of email/Teams message them to request access on myaccess.microsoft.com which could have an approval workflow and allow them access

Intune - Microsoft Tunnel VPN Gateway

A really neat but lesser known feature of Intune is Microsoft's Tunnel VPN solution which can do full device or per-app VPN tunneling on iOS and Android. This allows us to provide access to on-prem resources, restricted cloud resources, or ensure access to SaaS apps are coming from a known,

@interpipes That's pretty cool! I thought about using Smallstep for my example.

We didn't have an HSM, so we did OpenSSL on an encrypted removable drive (a couple actually, one offsite backup and one on-site in a fire safe).
