There is currently no integration build between Podio and Egnyte that I know about but are you or do you have a developer in-house? Then you can get access to our open API here: https://developers.podio.com/
And if you have any questions on the API please reach out on our developer forum: https://help.podio.com/hc/communities/public/topics/200069178-Podio-API-developer-forum
We can also help you to get in contact with one of our partners that can help to set it up :-)
Hope that helps!
