You leave a USB drive in a laptop bag, a meeting room or a taxi. Nobody can say who finds it, and the files on it are client lists, invoices or school records. That is the situation USB Flash Security## is built for: it puts a password and AES-256 encryption on an ordinary USB flash drive, so a lost stick is just a lost stick.
Quick facts
- Edition: ## (the top personal edition)
- Current version: 5.1.2
- Platform: Windows, including Windows 11 on x64 and ARM64
- Price: $49.99 per license, one-time purchase, no renewal fee
- Capacity: no limit on secured storage
- Drives per license: three USB drives
- Trial: 15 days free; a free edition (up to 4GB) is also offered
Key features
Your drive locks itself when you pull it out
The auto-lock kicks in as soon as you unplug the drive from the PC. You don't have to remember to lock anything, and a forgotten stick is already protected.
Files are encrypted as you copy them
The software uses AES-256. Data is encrypted automatically when written to the drive and decrypted automatically when read, so you keep working the way you always have.
Unlock the drive on a PC that doesn't have the software
A small unlocking tool is installed on the USB drive itself. You can open your data on another computer without installing USB Flash Security there, and secured drives can be used on multiple PCs.
No capacity cap, up to three drives
Lower editions stop at about 32GB, 64GB or 128GB. The ## edition has no capacity limit, and one license covers three USB drives. That makes it the choice for large flash drives and for USB hard disks, which the vendor's PRO Service add-on can also cover. You can swap drives too: uninstall the security from one and install it on another.
Version 5 adds a write-protect function
Version 5 added a write-protect function and formatting of the protected area with exFAT or NTFS. The latest update added support for Windows 11 on ARM64 and Windows Server 2025.
Who it's for
It suits anyone who carries work files on USB sticks and wants a password on them without setting up a full disk-encryption system. That includes freelancers, small offices and schools, and anyone with a big external drive. If you need to manage many drives from one admin PC, or buy five or more licenses, the vendor has separate g (group) editions for that.
