NIST 800-88 Purge Service
Data Destruction Inc. delivers Purge-level sanitization under NIST SP 800-88 r2 using the method that fits each medium: degaussing for magnetic drives, cryptographic erase for encrypted storage, and firmware secure erase for solid-state media. Every job ends with a serialized certificate.
Purge is the middle tier of the NIST framework, above Clear and below Destroy. It defeats laboratory recovery attempts while, for some methods, leaving the media intact enough to reuse. That balance is why Purge is the right call for many high-sensitivity drives headed for redeployment.

Hard Drive Degaussing
Degaussing is the Purge technique for magnetic media, erasing the magnetic field that stores data.
Cryptographic Erase / Crypto-Erase
Cryptographic erase is the Purge technique for encrypted storage, destroying the key that unlocks the data.
NVMe Destruction
NVMe destruction includes firmware secure erase, the Purge path for solid-state drives that will be reused.
DoD 5220.22-M Wiping Service
DoD 5220.22-M wiping is a Clear-level overwrite for cases that do not require laboratory-grade Purge assurance.
What is a NIST 800-88 Purge?
A NIST 800-88 Purge is sanitization that applies physical or logical techniques strong enough to make data recovery infeasible even in a laboratory. It is defined by outcome, not by a single tool, so the correct technique depends on the medium.
NIST SP 800-88 r2 lists degaussing, cryptographic erase, and dedicated firmware commands such as ATA Secure Erase and NVMe Format among Purge techniques. Each targets a different storage technology, which is why method selection is part of the service.
| Attribute | Value |
|---|---|
| NIST category | Purge (above Clear, below Destroy) |
| Magnetic method | Degaussing |
| Encrypted method | Cryptographic erase |
| Solid-state method | Firmware secure erase (ATA, NVMe) |
| Assurance | Defeats laboratory recovery |
| Reuse | Possible with non-destructive methods |
How does the Purge service work?
The Purge service works by identifying the storage technology, applying the matching Purge technique, and verifying the outcome. Data Destruction Inc. follows a documented sequence.
- Inventory each medium and identify its storage technology.
- Select the Purge technique: degauss magnetic, crypto-erase encrypted, secure-erase solid-state.
- Apply the technique to the standard defined in NIST SP 800-88 r2.
- Verify the result and record method against the serial.
- Issue the serialized certificate with the method documented.
When data sensitivity calls for the highest assurance, Purge escalates to a Destroy outcome, detailed on our Hard Drive Shredding page.
Why choose Purge over Clear or Destroy?
Purge is chosen when Clear is not strong enough but the media may still be reused, so it sits between the two other categories. Knowing when to use it prevents both under- and over-sanitizing.
- Stronger than Clear. Clear resists simple recovery, while Purge resists laboratory recovery, which higher-sensitivity data requires.
- Preserves reuse. Degaussed tape aside, methods like cryptographic erase and firmware secure erase can leave a working drive for redeployment.
- Meets strict policies. Purge satisfies frameworks that demand more than overwrite without mandating physical destruction.
Degaussing is a Purge that renders a magnetic drive permanently unusable, while Cryptographic Erase / Crypto-Erase is a Purge that can keep a drive serviceable. The method follows the medium and the reuse goal.
Which methods count as Purge for each medium?
The right Purge method follows directly from the storage technology, so here is the reasoning for each family.
- Magnetic hard drives and tape are purged by degaussing, which erases the magnetic field. See Hard Drive Degaussing.
- Solid-state drives are purged by firmware secure erase such as ATA Secure Erase or NVMe Format. See NVMe Destruction.
- Encrypted storage is purged by destroying the encryption keys, a cryptographic erase.
- Mixed environments receive the correct Purge per device, documented in one project record.
How does the Purge service meet compliance obligations?
The Purge service meets compliance obligations when the technique matches the medium and the outcome is verified and documented. The map below ties common rules to our process.
| Standard or rule | Requirement | Data Destruction Inc. process |
|---|---|---|
| NIST SP 800-88 r2 | Apply Purge techniques by media type | Degauss, crypto-erase, or secure-erase per medium |
| HIPAA 45 CFR 164.310(d)(2)(i) | Render ePHI unrecoverable | Purge ePHI media, verify and document |
| GLBA Safeguards Rule, 16 CFR Part 314 | Dispose of customer information securely | Purge with serialized certificate |
| CMMC and NIST 800-171 | Sanitize CUI to defined levels | Purge matched to CUI sensitivity |

Frequently asked questions
What is the difference between Purge and Destroy?
Purge defeats laboratory recovery and can leave some media reusable, while Destroy physically renders media unusable. Purge suits redeployment, Destroy suits maximum assurance.
Is degaussing a Purge?
Yes. Degaussing is a Purge technique for magnetic media. It erases the magnetic field and leaves the drive permanently unusable.
Can you Purge an SSD?
Yes, using firmware secure erase such as ATA Secure Erase or NVMe Format. Overwrite and degaussing are not reliable on flash.
Does Purge let us reuse drives?
Often. Cryptographic erase and firmware secure erase can leave a working drive, while degaussing does not.
How do you prove the Purge happened?
With a serialized certificate, a method record per medium, and a verification record tied to each serial.
Which method will you use on our media?
We select by storage type: degauss magnetic, crypto-erase encrypted, secure-erase solid-state, and document each. Call (866) 850-7977.
