This will break a lot of applications.
This is literally how our corporate network is setup. You MUST be on vpn or you cant get to anything. Makes the access permissions super simple. Prior to this setup there were authorization settings that differed between on-prem/off, on vpn or off, which office you were in, etc. now they just deny all unless you vpn in and then it uses your vpn account to validate access there, in one place. Saved a lot of headaches.
That is certainly a direction. I hope you have robust redunacies on the concentrator.
The above is just modern network security. The model is called zero trust.
Google pionerred it in the 2000s I believe, but its very normal now. A commom deployment will have an always on vpn agent on each device, which will then use mesh vpn tech like wireguard to do peer to peer connections between the client and server. There is no need for a central vpn controller. At most their is a dns-ish directory service that runs to let each agent queiry to get public keys for the other agents. Access is gated with RBAC and ACLs.
Tailscale is well known name that provodes this model. Netbird is a FOSS example.
That really depends on how the VPN is setup and configured on the company side. And possibly how the applications it their servers are configured as well. In our case, absolutely nothing breaks and it just works.
