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.
More and more laptops and workstations now come with the storage soldered onto the board, so the drive cannot be pulled out. That breaks the usual disposal plan: if you cannot remove the drive, physically destroying the data means destroying the whole machine, and there goes its resale or reuse value. ProofWipe wipes the drive right where it sits, with no disassembly and no shredding, so you get verified data destruction with a certificate to show for it, and the machine is still worth something afterward.
| 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 |
Yes · Partial / varies ·No. Comparison is against physical destruction and unverified wiping in general, not any specific product.
