Used protocols


I’ve been testing at a customer place the free version of Raidrive. The goal is to connect to a SFTP server and mount it under a drive letter. The customer’s network security policy only allowed SFTP on the machine. The free version did not start though Filezilla was running well against the given SFTP server.
We think that the pop-up advertisement window is using http protocol, thus blocking the app at startup if unavailable.
Is the licensed version only using the required protocol, in my case SFTP, not firing other unwanted protcols requests?
