What is a Degausser?
Essentially, a degausser is a machine that changes the magnetic domain of magnetic data storage devices where the data is stored. Examples of magnetic storage would be media like backup LTO and DLT tapes, VHS tapes, cassettes, reel-to-reel tapes and hard drives. Compact Discs (CDs) are not considered magnetic storage because the data is stored on the disc with optics. When the degausser is applied to magnetic domains the information is scrambled into random patterns. This process renders the data that was stored in these magnetic domains unreadable.
When is Degaussing Required?
Most of the time, degaussing is the only way to satisfy a federal requirement related to the sanitization and destruction of clearance-level information like “Classified” or “Top Secret.” In an attempt to protect the country’s classified information, several different federal agencies have standards and procedures that have been written on how to handle the destruction of sensitive data. Those standards involve the use of a degausser followed by physical destruction of the unit.
How is Your Service Licensed? What is the Cost Model?
Our services are customized based on each client’s quantity, frequency, and desired level of security.
Do You Provide this Service On-site or at Your Site?
The degausser is internally mounted and powered by our 26’ box truck so that the service can be provided at your site. However, we also have the capability to degauss the drives off-site at our secure, NAID-certified facility. This is typically done once or twice a week. For maximum data security assurance, we recommend onsite degaussing followed by onsite shredding.
Doesn’t the Degausser Need Periodic Calibration?
Yes, monitoring of the magnetic fields is done via a program we use called FieldCheckR. Our degausser is verified before every degaussing process to ensure that it is properly functioning. Not all degaussers have the ability to be tested using our digital read-out system with the FieldCheckR program.
Can You Degauss Solid State Drives?
Solid State Drives (SSDs) do not store data magnetically, so they cannot be degaussed. Please visit this blog post to learn more about the best practice for destroying information stored on solid-state drives.
Is There a “Degaussing” Equivalent or “Absolute Best Practice” of Data Destruction for Solid State Drives?
Yes, secure data shredding with a controlled, smaller shred width and particle size is the most secure method for solid-state drives. View more information on our blog by clicking this link.
If Degaussing is the Best Way to Destroy Data, Why Would I Shred My Hard Drives Too?
Shredding is an added redundancy to ensure the absolute destruction of data. Due to the fact that a degaussed drive and a non-degaussed drive physically do not look different, it is a best practice to shred drives after they are degaussed.
