I am a network admin working with BizTalk developers and clients, trying to hammer out a policy for secure file transfers.
Of HTTPS, FTPS, SFTP(ala SSH) or PGP, which is the most standard method without using 3rd party plugins (or least difficult) or burdening the outside party? Also, I need to be able to upload/download files independent of BizTalk.
current evaluation:
FTPS = firewall problems with some clients
SSH/SFTP = clients object to unwanted remote shell:
PGP = Devs will not work with it.
HTTPS = Not sure. (default support?)
