I like that its simple enough for non-technical people but if need be they can learn how quickly with other clients we've used in the past (iCloud/Dropbox). Not much so far as there is nothing particular i dont love yet - maybe if anything came along soon! We're looking into this because of our customers' demands of secure file sharing between them & us - their ability to view, edit, collaborate all without having anyone's credentials available online & no passwords etc stored anywhere. It is very easy to use and navigate. It has all of the features I need in order to be able to protect my information. The cost. There are so many options that come with this software it is difficult to figure out which ones will work best for me. Smartcryptor is protecting my online business by giving me control over what other people see when they look at financial information.
