Recently, the number of cybersecurity attacks has been steadily increasing.
For corporate users, access is provided through special extensions that allow traffic from a specific application to be routed through a tunnel. However, connecting a device to an MDM solution is convenient for large customers, but it creates challenges for small companies and developer teams that need to secure their network connections (for example, when a specific application must be isolated so that all of its traffic is routed exclusively through the tunnel), or protect their local infrastructure by preventing external applications from establishing network connections to unexpected servers (for instance, some applications may make requests to random servers in an attempt to determine their network environment).
perApp control on VPN is only supported on managed devices currently. But I do see the usefulness in supporting small scale device management outside the scope of MDM as well as perApp control in such environments. Please file a feedback to request such enhancement and describe in details your use cases. We will take that into consideration.
