1. What Is NIST 800-88?
The U.S. National Institute of Standards and Technology developed NIST 800-88 through its agency which provides cryptography and cybersecurity guidance that governments worldwide including the UK reference. The first version of the model (2006) introduced Clear / Purge / Destroy while the revised version, Rev 1, (2014) incorporated modern solid-state guidance and enhanced verification procedures. NIST 800-88 Rev-1 has become the standard worldwide language for proving data sanitisation because it covers both magnetic and flash media.
NIST 800-88, defines three clear outcomes for data-bearing items:
| Action | Goal | Typical Method |
|---|---|---|
|
Clear |
Overwrite data so ordinary software can’t recover it
|
Single-pass write
|
|
Purge |
Render data irretrievable with advanced tools |
Multi-pass wipe or degauss |
|
Destroy |
Physically destroy the media |
Crush or shred |
In plain English: if your organisation follows NIST 800-88 Rev-1, nothing readable survives.
1.1- How the NIST 800-88 Rev-1 Standard Defines Success
NIST doesn’t just say “wipe the drive” it specifies:
| Term | What NIST Requires | How National IT Disposal Exceeds It |
|---|---|---|
|
Media Preparation |
Identify type (HDD, SSD, hybrid)
|
Asset barcode + model scan ensures the correct method every time
|
|
Data Destruction Method |
Clear, Purge, or Destroy—chosen by risk level |
Certus multi-pass wipe, Intimus degauss, crush, or shred |
|
Verification |
Sample or 100 % check to prove zero data |
We use 100 % verification and log hash results in your certificate
|
|
Documentation
|
Record media ID, date, operator, method
|
We provide you with tamper-proof and genuine certification, send them to you and then store your PDF certificates and logs for five years

2. Why NIST 800-88 Matters for your organisation in the UK
The U.S. standards body created NIST SP 800-88, which now serves as the standard for secure data disposal throughout the Atlantic region. The Information Commissioner’s Office, along with financial services auditors in the UK, use NIST SP 800-88 as evidence to prove that digital media has reached an unrecoverable state. British organisations should follow NIST 800-88 because it provides the most straightforward method to meet GDPR requirements and Data Protection Act 2018 standards and sector-specific regulations without needing additional work or debate.
GDPR & DPA 2018
The ICO accepts NIST 800-88 as proof that data remains inaccessible, as the GDPR and DPA 2018 both “require appropriate technical measures” for data disposal.
The Financial Conduct Authority
Uses NIST as an industry-recognised standard for media destruction in many of its policy templates, according to FCA OPS 054.
ISO 27001 Mapping
Requires “secure media disposal” according to Annex A.8.3.
Reputation
The use of verifiable industry-recognised protocols becomes essential for both clients and regulators.
Audit Trail
The NIST 800-88 framework serves as the definitive audit trail standard which auditors expect to find.
3. How National IT Disposal Applies NIST 800-88
3.1- Our Data-Destruction Toolkit – Why It Gives Our Clients an Unmatched Edge
| Tool | Core Function | Why It Matters to You |
|---|---|---|
|
Certus Software (Purge/Clear)
|
Multi-pass overwrite or cryptographic erase for HDDs and SSDs; auto-verifies every sector and exports tamper-proof logs.
|
You get audit-ready evidence—drive make, serial, hash verification—without waiting for manual checks. Faster sign-off, zero dispute with GDPR or auditors.
|
|
Intimus 9000s Degausser (Purge)
|
Generates a 9,000-gauss magnetic field—over twice the minimum NIST requirement—for HDDS, data tapes, and legacy back-ups; 1.5-second cycle time.
|
Perfect for high-volume finance or healthcare archives: up to 300 drives per hour rendered unreadable before they ever leave your premises.
|
|
Intimus Destroyer 360 Crusher (Destroy)
|
12,000 lbs of crush force punctures and warps platters/flash chips; silent, dust-free operation.
|
Ideal for on-premises jobs where noise is unacceptable. Executives can witness physical destruction in real time.
|
|
Intimus FlashEx Shredder (Destroy) |
4 × 15 mm particle size for SSDs, USBs, tablets, and smartphones—well below NIST’s 6 mm max.
|
Offers definitive end-of-life for solid-state media that can’t be degaussed; output fragments are recycled by plastic and metal refiners, preserving your green credentials.
|
3.2- Our tools function together to provide you with protection:
Media-Matching Precision
Our expert Data Destruction Technician selects the most suitable NIST-approved method for each data-bearing item. Magnetic Hard Drives are either securely sanitised using Certus or degaussed in 1.5 seconds. Solid State Drives undergo Certus-sanitisation for reuse, or physical destruction involves shredding into 4 × 15 mm particles. Data-bearing items arrived sealed in your collection at our facility; each device is processed by the exact technique it needs—no shortcuts.
Real-Time, Tamper-Proof Reporting
National IT Disposal’s secure client portal obtains data from Certus logs, scanner information and processing time stamps. Our clients obtain real-time information through our system, which fulfils ISO 27001, PCI-DSS and NHS DSP requirements without requiring third-party sign-offs.
High-Volume Throughput Without Compromise
Banks of drives from data centres? Our toolset processes thousands of drives daily through Certus racks for parallel erasure, the Intimus 9000s for rapid degauss, and the Intimus FlashEx for continuous solid-state shredding. The large scale of our operations results in minimal interruptions to your decommissioning project.
3.3- Why Choose National IT Disposal for NIST-Compliant Data Destruction?
National IT Disposal offers NIST-Compliant Data Destruction services; many choose our services for the following reasons:
