The largest concern for most security aware users, is the risk to their personal data through theft of their device. Whether this be from an Airport, from a car or even  home or office.

What is FDE / System Encryption? “Full Disk Encryption”

“Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. Disk encryption prevents unauthorized access to data storage.

Encryption Options

To encrypt a Windows 10 system you have 2 choices, BitLocker or 3rd party encryption software. BitLocker is made by Microsoft and included with Windows 10 Pro, therefore if your a home user you would need to pay to upgrade from home to pro. There are a number of 3rd party software options, and I am not going to attempt to cover them all, however they fall in to two broad categories. Free (as in beer), some of which are also Free as is (Freedom, Free and Open Source Software FOSS), and commercial where you would need to part with your hard earned cash.

 VeraCrypt

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and that is based on TrueCrypt 7.1a.”. They have taken the truecrypt source code and has continued to develop it, resolving issues identified during the Truecrypt audit, and looking to continue building features.

The GPT problem

One of the core problems with some of these encryption solutions today is the lack of support for GPT, its likely if you are a Windows 8, 8.1 or 10 user, that you have a GUID Partition Table (GPT).
