IT asset disposition · NIST SP 800-88 Clear & Purge
Verified disk sanitization
you can prove.
ProofWipe securely erases drives so government and business workstations can be resold instead of shredded — with read-back verification and a tamper-evident certificate for every wipe.

Why ProofWipe
Built for audit-ready IT asset disposition
For ITAD vendors, MSPs, and gov / enterprise teams who need to prove data was destroyed — and keep the hardware’s resale value.
Audit-ready proof
A tamper-evident certificate (HTML + PDF) for every drive, secured by a SHA-256 log hash — the documentation auditors and chain-of-custody need.
Standards-based methods
Implements the Clear and Purge sanitization categories, mapped to NIST SP 800-88 and CSE ITSP.40.006.
Verified, not assumed
Read-back sampling (1%, 10%, or 100%) confirms the data is actually gone — verification is the point, not an afterthought.
Fail-closed safety
ProofWipe refuses to touch the system or application disk. A drive is wipeable only when it is positively determined to be safe.
Resell, don’t shred
Recover asset value and divert e-waste: sanitize workstations for resale instead of destroying serviceable hardware.
Offline by design
No phone-home, no telemetry. Runs from a USB stick with offline license keys — nothing leaves the machine.
How it works
From USB stick to signed certificate
- 01
Launch from USB
Run the portable app on Windows 10/11, or boot the WinPE edition to wipe the system disk itself.
- 02
Select drives — safely
Fail-closed protection auto-guards the system and app disks. BitLocker and hidden HPA/DCO areas are detected up front.
- 03
Arm & sanitize
Two-step arm, then Clear (overwrite) or Purge (firmware sanitize). Wipe multiple drives in parallel.
- 04
Verify & certify
Read-back verification runs, then a tamper-evident certificate is generated — for every outcome, including partial wipes.
Capabilities
Two ways to sanitize — one way to prove it
Clear vs Purge
Overwrite user-addressable storage, or invoke the drive’s own firmware sanitize (ATA SANITIZE / Secure Erase, NVMe Sanitize / Format).
Bootable WinPE edition
Wipe the Windows system disk and sealed devices like Surface by booting from ProofWipe media.
Multi-drive batch
Sanitize many drives at once with isolated, per-drive sessions, progress, and certificates.
HPA/DCO detection
Detects hidden host-protected and device-configuration areas and discloses them on the certificate.
Standards & compliance
Grounded in published sanitization standards
ProofWipe implements the Clear and Purge sanitization categories defined by NIST SP 800-88.
- Clear
- Overwrites user-addressable storage so data cannot be recovered with standard tools.
- Purge
- Uses the drive’s own firmware sanitize commands to render data recovery infeasible even with laboratory techniques.
ProofWipe implements published sanitization standards. It is not a third-party-certified product.

Illustrative sample — not a real certificate
Why not just shred?
Destroy the data, not the asset
Shredding destroys resale value and creates e-waste. Verified sanitization preserves the hardware for resale while still documenting that data is gone.
| Capability | Physical shredding | Typical unverified wiping | ProofWipe |
|---|---|---|---|
| Data rendered unrecoverable | Yes | Partial | Yes |
| Read-back verification | No | No | Yes |
| Tamper-evident certificate | Partial | No | Yes |
| Hardware kept for resale | No | Yes | Yes |
| Diverts e-waste | No | Yes | Yes |
| Standards-based method | Partial | No | Yes |
