For commercial solutions take a look at zscaler offerings. The biggest problem in such solutions is that you have to identify the applications you have and sure Google is a relatively new tech company. Try to identify all apps/services on big old companies. Until you do that or decommission them, hou have either to keep your old VPN solution up or proxy ALL traffic and use the analysis tools they have to identify apps/services, again no walk in the park. Of course as mentioned Google has most of its apps/services anyhow on the Internet so you mostly just use the host checking and client identification functionalities of such tools.
