Degaussers and Degaussing Solutions
Secure magnetic data erasure for hard drives and tape media
Organisations retain large volumes of sensitive information on disk drives, backup tapes and magnetic media. When those assets reach the end of their life, deleting files or formatting the drive may not be enough to prevent information from being recovered.
Degaussing uses a powerful magnetic field to disrupt the magnetic domains in compatible storage media. This permanently removes the recorded data and renders the media unusable, helping organisations reduce data breach risk and meet their internal security and disposal responsibilities.
Varese Secure supplies professional Garner degaussing equipment for organisations that need controlled, repeatable and verifiable data erasure.
Data Destruction from Garner Products
Varese Secure is an international distributor of Garner Products equipment across the EMEA region.
Garner manufactures professional degaussers, hard drive destroyers and verification systems for organisations that require secure and repeatable media sanitisation. Its degaussers are designed to erase compatible magnetic media, including hard disk drives and selected tape formats such as LTO and DLT.
Garner equipment is available for different workloads, from compact units for routine processing to high-volume systems for data centres and large IT estates. Physical destruction equipment can also be used after degaussing where an organisation’s security policy requires the media to be rendered visibly and permanently unusable.
Optional IRONCLAD verification technology can record processing activity and help create an audit trail for internal governance, client assurance and compliance reporting.
Secure Data Disposal for Sensitive Magnetic Media
Organisations entrust their storage media with customer records, financial information, intellectual property, employee data and other confidential material. That information must remain protected throughout the disposal process, not only while the media is actively in use.
Varese Secure provides professional degaussing equipment designed to permanently erase data from compatible magnetic media. Solutions can be selected according to the type of media, required throughput, security classification and level of reporting needed.
Permanently Erase Data from Magnetic Hard Drives
Degaussing changes the magnetic properties used to store information on a hard disk drive. When the correct equipment is used for the media, the recorded data is permanently erased rather than simply hidden or deleted.
Powerful Erasure for Hard Drives & Magnetic Tapes
Each degausser generates a controlled magnetic field designed to exceed the coercivity of compatible media. This allows data to be erased from working or non-working hard drives and supported tape formats without relying on the device’s operating system.
Deleting files or reformatting a drive changes how the information is accessed but may leave recoverable data on the media. Degaussing instead disrupts the magnetic domains that hold the recorded information, permanently erasing the data and making the hard drive unusable.
Degaussing is intended for magnetic storage media. Solid-state drives, USB devices and memory cards store information differently and require an appropriate physical destruction method.
Permanent Erasure of Magnetic Media
Garner degaussers are engineered to produce an erasure field suitable for specified magnetic storage media. Built-in diagnostics on selected models confirm that the required field strength has been achieved during each cycle.
Compatible media may include:
- Conventional magnetic hard disk drives
- LTO and DLT backup tapes
- Selected magnetic cartridges
- Working and non-working drives
The correct degausser must be selected for the coercivity, dimensions and volume of the media being processed. Varese Secure can help organisations assess these requirements before choosing equipment.
Fast, Repeatable Media Processing
Degaussing can process compatible magnetic media in a controlled cycle without waiting for software overwriting procedures to finish. Depending on the selected model, individual drives or tapes can be erased within seconds.
This can help organisations:
- Process large quantities of end-of-life media efficiently
- Reduce backlogs of devices awaiting disposal
- Apply the same erasure process to every item
- Handle damaged or non-functioning drives
- Maintain a consistent workflow for staff
High-volume models are particularly suitable for data centres, IT departments and organisations that regularly retire large numbers of storage assets.
Supporting Secure and Accountable Data Disposal
UK data protection requirements do not prescribe one universal destruction method for every organisation. Businesses must select security measures that are appropriate to the sensitivity of the information, the storage medium and the risks involved.
The Information Commissioner’s Office identifies wiping, degaussing and hardware shredding as possible methods for secure electronic data disposal. It also recommends documenting the chosen method, securing devices while they await destruction and keeping records of assets sent for disposal.
A controlled degaussing process can support these responsibilities by providing:
- Permanent erasure of compatible magnetic media
- A consistent and repeatable processing method
- Records linked to individual assets
- Verification that the required erasure field was achieved
- Evidence for internal audits and customer assurance
The appropriate process should be defined within the organisation’s retention, information security and media disposal policies.
Responsible Processing After Data Erasure
Once magnetic media has been securely degaussed, it can be directed into an appropriate physical destruction or recycling process according to the organisation’s security policy.
Where recycling is permitted, recoverable materials should be separated and processed through suitable waste streams. This allows organisations to combine secure data disposal with responsible management of end-of-life IT equipment.
Degaussing itself does not make a hard drive suitable for reuse. The process normally renders the drive permanently inoperable.
Speak to Varese Secure about the type and quantity of magnetic media your organisation needs to process. We can help you compare equipment based on erasure strength, cycle time, media capacity, verification requirements and expected workload.

Our team can explain how degaussing works, which media formats can be processed and whether your organisation would benefit from additional physical destruction or verification technology.

Degauss. Destroy. Verify.
A layered process can provide additional assurance where an organisation handles highly sensitive, regulated or classified information.
Degauss: Permanently erase the information held on compatible magnetic media.
Destroy: Physically damage the media so that it cannot be reused or returned to service.
Verify: Record the asset, processing cycle and destruction outcome to create an auditable trail.
The correct combination depends on the type of media, the sensitivity of the information and the organisation’s own disposal policy. UK GDPR does not automatically require every hard drive to be both degaussed and physically destroyed.
Certificates and processing records can support accountability, but they should accurately correspond with the assets submitted and the work completed. The ICO recommends checking that destruction certificates match the equipment sent for disposal.
Extended Warranty Options Available
Extended warranty options are available for selected Garner equipment, providing continued support beyond the standard warranty period.
Varese Secure can explain:
- What the standard manufacturer’s warranty covers
- Which extended warranty options are available
- The applicable warranty period
- How technical support and repairs are handled
- Any conditions or exclusions that apply
Speak to our team before purchase to confirm the warranty arrangements for your chosen model.
Choose a Degausser That Fits Your Data Destruction Process
The right equipment depends on more than the number of drives being processed. Your organisation may also need to consider media dimensions, coercivity, security classifications, available workspace, operator requirements and the records needed after each cycle.
Varese Secure can help you assess:
- The types of hard drives and tapes in your estate
- Your average and peak processing volumes
- Required cycle speed and media capacity
- Whether equipment will be used at one site or transported
- Verification and reporting requirements
- Whether physical destruction is also needed
This creates a solution that fits your operational process rather than relying on a one-size-fits-all recommendation.
Build a Controlled and Traceable Destruction Process
Secure data disposal requires control before, during and after erasure. Media awaiting processing should be identified, stored securely and restricted to authorised personnel.
Where reporting technology is used, each asset can be linked to a processing record. This helps organisations demonstrate what was processed, when it was processed and which method was applied.
The NCSC advises organisations to assess the information held on storage media, sanitise it appropriately and ensure that it cannot be read by unauthorised parties after leaving organisational control.
Varese Secure can provide guidance on integrating degaussing and verification equipment into an existing IT asset retirement or data disposal procedure.
