Working with SecureTrack mainly means to work with a Browser connected to the SecureTrack Server. If nothing is done, an automatic logout is initiated by the system. The time untli this logout happens, can be configured.
Sometimes a logout from the WebUI happens while the administrator works. This should not happen and seems to be a "feature" of versions up to and including 17-2.
With 17-3 and subsequent versions Tufin has changed the authentication method to Keycloak. These versions don't show this effect any more.
If there is a problem with automatic logout while working with the WebUI, an upgrade to 17-3 or newer is recommended.
