File Encryption | Mac

Sponsored Content By ShareFile

When you need to send sensitive data — such as files and folders — via email, you should encrypt those files to ensure they are protected. File encryption for Mac users is relatively simple. Mac computers have a built-in feature called Disk Utility that enables you to encrypt files, but it involves a lot of steps. Mac users can also easily encrypt files as well as store and share them using Citrix ShareFile.

While Disk Utility is a free service that comes with your Mac, it doesn't offer the same level of protection that ShareFile does, which is highly important when dealing with sensitive data. 

1. Encrypting files on Mac — Disk Utility

First you'll need to locate the Disk Utility application on your Mac. You can do this by using Spotlight or by locating it in the Utilities folder. Once you've located and opened Disk Utility, select:

 File > New > Disk Image from Folder

Locate the folder you want to encrypt and select it, choose your encryption method and save. Now your file will be encrypted when it is closed.

This method works if you only plan on storing your file, but if you need to share your file, you'll need a better solution, such as ShareFile. 

2. Encrypting files on Mac — ShareFile

To encrypt files with ShareFile, simply sign up for a free 30-day trial and open the ShareFile web application in any browser on your Mac. You can upload files and create folders by selecting the Upload Files button from the navigation bar.

Once your files are uploaded into ShareFile, they're protected by 256-bit encryption and stored in SSAE 16 Type II (SOC1), SOC2, and ISO 27001 accredited datacenters. You can even share encrypted files via email as ShareFile uses no less than 128-bit encryption for files in transit.  

ShareFile is an easy and secure way to encrypt files on your Mac. And all you have to do is sign up for a free 30-day trial to get started (no credit card required).
