Frequently asked questions

Straight answers about certification, running tScrub on your own hardware, and edge-case drives.

Compliance & certification

Is tScrub NIST 800-88 certified?

tScrub maps its wipe methods to NIST 800-88 Clear, Purge, and Destroy outcomes, but it is not itself a certification. Compliance certification is typically issued by an accredited body for your specific process.

How does tScrub support UK GDPR?

Verifiable erasure with a chain-of-custody report supports the UK GDPR right to erasure, giving you documented evidence that data has been destroyed.

Building & running

Can I build the appliance myself?

Yes. tScrub is a single self-contained script. Boot it from USB or PXE on any Linux environment that meets the documented dependencies — no vendor hardware required.

Which drive types are supported?

NVMe (crypto, block, and overwrite sanitize plus format), SATA/ATA (enhanced and standard security erase), and SCSI/SAS via nwipe. USB-attached drives are excluded by design.

Do I need an internet connection?

No. tScrub runs fully offline. Copy the report files off the appliance by USB and upload them in the dashboard, or configure optional FTP upload — ideal for air-gapped decommission labs.

What if a drive can't be wiped?

Frozen, locked, or unsupported drives are flagged with a FROZEN or BLOCKED status and a PHYS_DESTR certification in the report, so the device can be routed to physical destruction and still documented in the chain of custody.

Accounts & licences

Do I need a licence to run tScrub?

Yes — every tScrub build requires a licence, even the free tier. Sign in and issue one from your dashboard; free licences are instant.

What's the difference between a free and a paid licence?

Both erase drives the same way. Every report is signed with Ed25519: free licences self-sign with an appliance-generated key (tamper-evident, not attributable), while paid licences embed a vendor-signed report key, so reports are verified against that key and attributable to the licence (the licence itself verifies against the tScrub vendor key). Certificates are available on every tier and every one carries a verification QR code; paid licences add a digitally signed PDF.

How do I get my reports into the dashboard?

Upload the report files on the Reports page of your dashboard, then generate a Certificate of Destruction from the Certificates page. Per-drive and pre/post-wipe SMART data is shown on the Reports page.

Pricing & company

Is VAT included in the price?

Prices are shown in GBP and exclude VAT, which is added at the applicable UK rate at checkout.

Is tScrub made in England?

Yes. tScrub is made in England, with pricing in GBP and documentation that references UK GDPR and ICO guidance.
