Proton T-4 overview

The Proton T-4 is an NSA/CSS Evaluated Products List degausser that produces a bi-directional 20,000 Gauss positive and 20,000 Gauss negative field. It is the model most often specified in Indian government, defence and PSU tenders where an NSA listing is a mandatory technical requirement.

The Proton T-4 Hard Drive Degausser is listed in the National Security Agency's Evaluated Products List (NSA EPL-Degausser) for Hard Disk Drive Degaussing, offering the most effective data sanitization on the market. The Proton T-4 removes data from all magnetic devices, including Laptop, Desktop & Network Hard Drives, and LTO & DLT Tapes. Simply drop your magnetic media into the slot, push the button and the degaussing process will begin. In under one minute, the Proton T-4 eliminates all traces of your confidential and classified information.

The Proton T-4 Hard Drive Degausser produces a bi-directional field which provides a 20,000 Gauss positive field and a 20,000 Gauss Negative field. The T-4 achieves this by using a unique, patented “Reverse Polarity”. Other degaussers may have either a positive or negative pulse, but only one. The T-4 has both and it is fully automatic. This ensures complete and permanent erasure of your data and will protect your sensitive information for years to come.

The T-4 now has a LCD screen and internal Gaussmeter for performance verification. This new feature guarantees that your hard drive degausser is performing to NSA standards every time and eliminates the requirement of separate instruments to check field strength and/or re-certification programs.

Who it is for

Proton T-4 is the right machine when you are handling defence & armed forces, central & state government, psus & banks, or similar environments.

Proton T-4 in India — supply, service and compliance

  • The single most-specified model in Indian defence, PSU and police tenders that mandate an NSA EPL listing.
  • The internal Gaussmeter removes the annual re-calibration instrument purchase many Indian buyers budget for separately.
  • 12 V battery operation lets you install the T-4 in a secure room without touching the mains — useful for defence and bank strong-room-adjacent areas.
  • Quoridge supplies the T-4 with a 230 V / 50 Hz Indian configuration and can quote the rugged wheeled deployment case for field teams.

Options and accessories

12 V battery operation; extended warranty; mobility cart; and a rugged custom deployment case with wheels that lets the T-4 operate while still in the case — useful when a machine has to be moved between secure rooms or to a client site.

Frequently asked questions

Straight answers to the questions Indian buyers ask most often. Cannot find yours? Call us — we answer technical questions on the phone.

What is the NSA EPL and why does it matter in India?
The NSA/CSS Evaluated Products List is the US National Security Agency's list of evaluated data-destruction equipment. Indian defence, PSU, police and many banking tenders specify an “NSA-listed” or “NSA/CSS evaluated” degausser, and the T-4 appears on that list.
What is Reverse Polarity?
Most degaussers deliver a single-polarity pulse. The T-4's patented Reverse-Polarity design delivers both a strong positive and a strong negative pulse automatically, which is more thorough at randomising the magnetic domain of the platter.
Do I still need a crusher after degaussing?
For unclassified-to-classified magnetic media, no — the T-4 alone is a valid sanitisation method. For physical destruction as an additional precaution, and for solid-state media, a PDS-100 crusher and PDS-88 shredder are used alongside.
Can the T-4 run without mains power?
Yes, a 12 V battery operation option is available, which allows the T-4 to run in a secure room with no mains connection.
