QNAP rolls out the public QTS 5.2 beta with enhanced security


QNAP has released the public beta for QTS 5.2, featuring a Security Center to monitor file activity to counter ransomware threats. With support for TCG-Ruby self-encrypting drives (SED), QTS 5.2 is set to become more secure than ever. QNAP is certainly working on securing NAS enclosures after the increase in ransomware.

What’s new in QTS 5.2

As well as the new Security Center, QNAP has made notable improvements to the NAS OS. Numerous optimizations have been made to the operation, configuration, and management of the enclosure, improving the user experience. Kernal Mode SMB Daemon is fully supported in QTS 5.2 to improve transmission performance.

The TCG-Ruby standard provides specifications for NVMe storage, encrypting the drive through the built-in processor. When backing up a QNAP NAS with QTS 5.2, you’ll receive backup content info including system, network, and permission settings. These can then be selected when restoring a backup.

A neat improvement is the uploading of a list detailing all the installed apps on a NAS, which can then be used to quickly reinstall them on a new QTS installation. With the latest version, QNAP was able to improve startup and shutdown speeds by up to 30%, though we’ll need to boot up the OS beta on our enclosure to confirm.

You can read all about the QTS 5.2 beta on the official QNAP website.

How to join the beta

There’s no application form to fill out. Simply download the beta from the QNAP website and manually update your enclosure.


Do not install this beta update on your live environment. It’s still in testing and there’s a slim possibility it may brick your enclosure. Only use the beta on a test NAS or one where all data has been backed up.

  1. Download the QTS 5.2 beta. (Choose your NAS from the drop-down menus.)
  2. Log into your QNAP NAS.
  3. Open Control Panel.
  4. Go to System > Firmware Update > Firmware Update.
  5. Click Browse.
  6. Select the downloaded QTS 5.2 beta OS update file.
