Full discloser: I'm a founder at Cloudtenna.

AeroFS is a great option for file-syncing. Compare public file sync (Dropbox), private file sync (AeroFS), and traditional network file shares (CIFS/NFS).

Can you risk files in the public cloud? If no, you're limited to just private file sync and traditional network shares. And this is where AeroFS can shine.

You may already have a network share. Its secure. But its a pain to access remotely (VPN) and mobile devices are not compatible at all. So you may choose to migrate your files into an AeroFS Private Cloud so you can sync files instead of browsing files via the network. Syncing files to your desktop gives you offline/remote access.

I'd argue the most secure option is probably leaving data where it already is. If you already have a file server, with permissions and such thats already vetted secure. Cloudtenna adds mobile file access to your on-prem file server. No need to migrate files to a new storage platform.

My blatant pitch aside, AeroFS is right solution if you want to replace mounted network file shares with file sync. Cloudtenna, instead, is good for adding the web/mobile access features of Dropbox to your existing network shares.
