Push installs are absolutely a thing, depending on your environment.
Active Directory, GPO, etc, etc...
On my office PC, everything is pushed from the network.
Office, AV, VPN clients, Windows updates and versions, etc, etc.
For YOUR environment, his depends on your level of access and control over the employees systems.
Installation of a VPN client on teh users PC is little different than installation of any other application.I know how to automate sandbox installs. I need a VPN service that supports a silent install so I can auto install it too. I just need to know what company has a client that can do a push install so I can automate it.
What VPN client do you use that can be pushed?
"The rest was an examples of why silent installs might be needed by others..."
As I understand your post "others" do not need or want VPN - correct? What is their reasoning and basis for not wanting VPN?
And, even if they do not want VPN do you intend to silently push VPN out anyway?
Again who owns the laptops? What is the business case for silently pushing VPN to the sales folks?
It seems to me that that the first objective is to honestly convince ("sell") the sales folks that VPN will truly help them in some manner.
Per the other posts, getting VPN out there is not the issue. Certainly not a technical issue.
What about my other questions....?
