Meet Guardonix

USB3.0 Writeblocker and Stabilizer

A better writeblocker which will not allow your data acquisition process to be interrupted due to intermittent read instabilities.


"Guardonix is now a mandatory part of my DFIR kit. You should seriously consider one for yours too." - Brett Shavers, DFIR Training

"I have to congratulate the DeepSpar team because, in my opinion, they have developed a very interesting product." - Marcos Fuentes


Enables forensic acquisition of USB storage devices by blocking all write commands to preserve data integrity.

Helps prevent Windows from freezing, crashing, and/or dropping USB storage devices due to bad sectors or other read instability issues.

Professional Edition

Speeds up bad sector processing by up to 25+ times, allowing Windows-based tools to work with highly unstable drives.

Extended configuration options and status information which shows how well data acquisition is proceeding in real-time.

USB protocol requires the PC and storage device to be in constant synchronization with one another. If the storage device fails to respond quickly enough, or responds irregularly due to bad sectors or other read instability issues then it may lose its current state and become desynchronized with the PC. The only option for Windows to regain access to the device is to reinitialize the whole connection, which means re-mounting the USB device in the system, thereby interrupting any data acquisition procedures which are currently in progress.

Guardonix hardware stands between the PC and the storage device, making sure that the connection to the PC is always well-maintained, regardless of what’s happening with the storage device. This way even if the storage device becomes desynchronized, only it’s connection to Guardonix hardware will be reinitialized, which will not have any impact on the PC, allowing data acquisition to proceed without interruption. Guardonix hardware even allows for the storage device to be entirely disconnected, during which time the PC will simply wait until it’s reconnected before seamlessly continuing with data acquisition.

About our company

Guardonix is the latest release from DeepSpar, a Canadian manufacturer of professional data recovery equipment since 2004. Guardonix takes advantage of key functionality which was previously only offered by professional data recovery tools to help visualize, track, and control the data acquisition process.
