What aspect of security are you referring to or do you just mean overall?
I have been using mediacloud ( http://mediacloud.cc/ ) for the past few months and I've been very impressed with it. They have built-in file acceleration to give you the maximum upload speeds your network allows. I've been using it to upload files anywhere from 1mb to 20gb and have never had a problem.
As for security I know they use AES256 SSL, but again, am not sure which aspect of security you are interested in.
