I have a number of large files (less than 20MB) I need to receive from a client, but they contain confidential information that we want to keep protected.
Recently, we’ve been having trouble with things gettings dropped from our e-mail, so I am looking for an alternative source. However, some of these clients are not the most tech savvy (some of them have trouble with printing and scanning) and I want to keep things as simple as possible for them, while also keeping the files secure.
After reading an article on your website, I found some alternatives, which could be useful but nothing regarding how secure they are was mentioned.
My question is: What is the safest, simplest alternative to DropBox?
