Steganos Privacy Suite is a comprehensive collection of tools for keeping your personal information safe from snoopers.
Steganos Safe stores confidential files in a secure password-protected vault. It's able to encrypt data on your hard drive, USB keys, even cloud files (Dropbox, OneDrive and Google Drive are supported).
If that's too obvious, you can hide a Safe inside a multimedia file so that no-one even knows it's there.
Privacy Suite includes a password manager where you can save your logins, bank account details, credit card information, even "Private Favourites", URLs you'd like to keep handy, but not make entirely public.
An Email Encryption module can encrypt your message text and file attachments, making sure your private communications stay that way.
There are general online privacy tweaks to block ads, social tracking buttons and anonymise your browser type.
The "TraceDestructor" securely deletes your browsing and Windows traces to prevent others checking your activities.
Steganos Suite is rounded off with the Shredder, which wipes confidential files or free space to ensure they can't be recovered later.
A versatile suite of tools, highly configurable and with a lot of features and functionality. You could still create something similar by combining the best-of-breed freeware, but it would take a while and your choices wouldn't be integrated.
