Our use case is simple as are many businesses.
We have users that authenticate using Google lets say. We want to give them remote desktop access from their home. They ARE NOT techies.
Ideally we could give them an SSO login (it sounds like this will make that possible). And then authorize them to connect to nodes Y and Q. We don't need "networks" at this level, just user A authorized to connect to node Y or node group 5 etc.
if we have users and user groups and nodes and node groups you can then basically do whatever a business is used to doing (this breakout is common in many smaller businesses using Active Directory, Google etc).
This seems boring but the competition is pretty poor. Sonicwall and friends with VPN setups are time consuming and pretty complex to manage and deploy. Anydesk and friends have just horrible business practices (try cancelling).
Cloudflare is getting there sort of with WARP, but it's also awkward and they keep moving their product positioning around.
Note - we happen to use some mikrotik for fun as well as sonicwall supported by our third party MSP - we've started to see zerotier show up on mikrotik which has been fun.
