The tunnelers are your friends there. We have them for all major desktop/mobile os'es. They are "basically a vpn client" but with all the actual zero trust goodness you'd expect...strong identity, policy based security etc. We realize you can't just embed zero trust into all your apps right from the start. it's a journey! :)

You should check them out. Lots of videos showing interesting features over on youtube too if you like a video... https://www.youtube.com/channel/UCAsrfQasdZmp2Gq07Ej_5cQ/vid...
