I'm looking for File encryption on file shares where multiple users have to access a file.
My first approach was EFS but that not good solution for file shares only for local encryption.
Another option would be to use software from Symantec, but actually I don't want another system that i have to administrate.
Since we are using SharePoint 2010 and hopefully as soon as possible 2013, I thought I might be able to use SharePoint as a secure data storage. I know I can setup Client Certificate Authentication via ADFS for SharePoint so I would have a secure access.
The other Part would be to secure my data. Is there any encryption for files in SharePoint so that someone cannot steal my data and open it?
