The only app-specific tunneling Pulse Secure offers on OSX today is provided through a utility called JSAM. You can read about it here:
You would need to talk to your system administrator about the possibility of having your Pulse Connect Secure gateway configured to work with JSAM.
In the longer term, we hope to add app-specific tunneling to the Pulse Secure client on OSX. Feel free to reach out to your authorized support representative to convey your specific needs so we can consider them for future releases.
