Espionage provides secure folder protection. Unobtrusive, intuitive, and simple to use. Espionage is designed to integrate with Apple's Finder seamlessly, so that you can protect only the data that you want protected, and without having to resort to any special "vaults".

Features:

Protect Individual Folders:
Until now it has been surprisingly difficult to password protect a folder on Mac OS X. Now, Espionage is here to solve that problem for good. By encrypting only what is necessary, Espionage lets you stay secure while avoiding the penalties of encrypting too much.

Protect Application Data:
Many applications can inadvertently store valuable private information without encrypting it. Espionage is the only security tool for the Mac that lets you selectively secure application data like email and chat history.

Seamless Finder Integration:
Espionage provides you with a simple to use interface to configure your protected folders and then gets out of the way. Once a folder is protected, simply double-click on it in the Finder and enter your password at the prompt to unlock it. It's that easy.

AES-128+256 Bit Encryption :
Espionage uses the same powerful AES-128 encryption used by Apple's FileVault, but in addition to AES-128, Espionage includes support for AES-256, for those truly important files. Even the National Security Agency (NSA) has stated that it can be used to protect TOP SECRET classified information.

Built-in Backups:
Espionage comes with built-in backups, custom-fitted for the way it works with folders. This means it no longer matters whether the folder is locked, or unlocked. Espionage will backup your folders safely and efficiently, making it easy to restore them later if disaster strikes.

Encryption-less:
Protection Espionage can securely protect important data through encryption. But it can also insecurely guard unimportant data. For example, you might have a collection of videos that you don't want your grandma to have access to but don't care enough about to encrypt. Espionage can put a password on that folder in a flash without touching its contents.

Limitations: 14-day trial.

Requirements:
OS X 10.11+
