Since the likelihood of your sensitive data getting exposed increases when you are using certain applications, it might be best to use encryption software for your Mac apps. Cisdem AppCrypt is quite possibly the best option for doing this. This app encryption software for Mac is easy to use and yet very effective in protecting sensitive data on your Mac. AppCrypt safely locks apps without the need to modify system files or settings. All you need to do is to provide a strong password and the software will do the rest of protecting your data.

2. GNU Privacy Guard

When it comes to email encryption, probably one of the best options, if not the best, is GNU Privacy Guard. Based on PGP (Pretty Good Privacy), this open-source implementation lets you encrypt attachment files and the message content of your email. This Mac encryption tool uses a hybrid encryption software program to keep data in your email safe. It also uses the tried-and-true combination of conventional symmetric-key cryptography for encryption speed. The software also features keychain management.

4. Concealer Encryption Software for Mac

This Mac encryption option is easy to use. When I say easy to use, I mean you just need to drag files from one folder in Finder and drop them into Concealer. The software automatically encrypts those files. Concealer also keeps encrypted files small, so you don’t have to worry about storage space.

The software uses a main database protected by a master password. Meanwhile, files and folders are protected by individual passwords. Concealer is available for only $19.99. A free trial version can also be downloaded from the developer’s website.


  • Drag and drop files to be encrypted.
  • Works very well with Mac.


  • Deletes data from Desktop only and not from Mac Hard Drive.

5. FileVault for Mac

When it comes to encrypting your Mac’s hard disk, FileVault is possibly your best option. The software encrypts your entire macOS volume, including your home directory. It also helps prevent unauthorized access to your documents and other information stored on your Mac’s startup disk.

FileVault requires you to create a “Master Password.” You can use this in the event that you lose the FileVault account password. Did I say that FileVault is built-in with any macOS? Yes, it’s Apple’s built-in encryption tool for macOS.

To check if FileVault is enabled on your Mac, go to System Settings > Privacy & Security > File Vault.


  • Built-in encryption software included with macOS.
