USB Flash Security is a software that can provide your USB flash drives with protection, by encrypting them.

Since this is an ad-supported product, you should pay special attention when installing USB Flash Security. It automatically makes some changes to your web browsers, unless you switch to custom installation mode.

The interface of the program consists of a standard window in which you can select an available USB flash drive and press the "Install" button.

So, you can add a password and optionally a hint. But you can also enable the program to encrypt (AES256) the "Protected area".

In addition, you can use "Copy of release tool" and "Copy of Safely Remove tool", view the model, size, vendor and serial number of the flash drive, as well as update information.

The program takes up a low-to-moderate amount of system resources, contains a help file (which is written in English but has poor grammar) and didn't freeze, crash or pop up errors during our tests.

However, in the free version you cannot access all the functions of USB Flash Security (e.g. input user information). Plus, when you install it on your flash drives, data will be erased (you are warned by the program), so you have to backup your files and folders.

All in all, USB Flash Security provides a simple and effective solution when it comes to password-protecting your USB flash drives. We strongly recommend it to all users.
