We've highlighted many ways to help you share files over the internet. Newly launched service WatchDox aims to make the document-sharing process more secure.
Once you've chosen and uploaded the document(s) you want to share, WatchDox lets you enter your recipient's email address along with your own, which WatchBox will validate. Then you can select what permissions you want to give to the person you're sharing with—including whether they can print, forward, or copy the document. You can also set when you want the document to expire (maximum 30 days).
As its name implies, WatchDox lets you track who views and opens your documents and modify the permission settings as you like. You can send an unlimited number of documents (uploaded two at a time, up to 15MB), and store up to 50MB online. There's also a Microsoft Outlook plug-in available for download to share directly from Outlook.
Of course, WatchDox can't guarantee 100-percent safe document transfers—it can't prevent someone from taking a screen grab, for one—but the service provides enough added security benefits to make it worth a look. WatchDox is currently in beta and free to use.
