Certified Data Sanitisation & Secure Drive Destruction
Data breaches during IT decommissioning carry severe regulatory and financial risks. At Sierra Indigo, our secure data sanitisation workflows align strictly with NIST SP 800-88 Rev. 1 (Purge/Clear) and current NCSC guidance. Whether sanitising high-density server SANs, enterprise NVMe storage, or studio workstations, every media carrier is serialised, tracked, and certified inside our secure UK facility.
1. Software Sanitisation (NIST 800-88)
Cryptographic and multi-pass overwriting protocols applied to reusable hard drives and SSDs, ensuring data is irrecoverable while preserving hardware value for ITAD resale or redeployment.
2. Physical Drive Destruction
For high-security clearance requirements, failed drives, or obsolete magnetic and solid-state media, we execute industrial physical shredding and degaussing directly at our facility.
3. Serialised Audit Reporting
Every individual hard drive, blade, and chassis is scanned by serial number prior to processing, generating a tamper-proof Certificate of Data Destruction for your compliance records.
Rigorous Chain of Custody & Regulatory Alignment
Our data destruction processes are engineered to satisfy corporate governance, ISO 27001 mandates, NCSC guidance, and UK data protection legislation:
- UK GDPR Compliant: Complete mitigation of liability regarding sensitive customer and proprietary corporate data.
- NIST SP 800-88 Purge Standard: Advanced sanitisation techniques that render target data recovery infeasible using state-of-the-art laboratory techniques.
- Detailed Asset Manifests: Serial-number-level tracking matching every drive to its final status (sanitised for reuse or certified destroyed).
- Secure Transport Protocol: Tamper-evident, locked transit containers used from your site directly to our secure UK processing bays.
In-House AATF Sanitisation & Shredding — Zero Third-Party Hand-Offs
The biggest risk in data destruction is third-party subcontracting. Because Sierra Indigo operates as a direct UK Approved Authorised Treatment Facility (AATF), approved by Natural Resources Wales, your data-bearing drives and storage arrays are never passed through unlicensed brokers. Every drive is wiped or physically shredded in-house under our direct chain of custody, with raw materials processed via compliant WEEE recovery.
- Unbroken Chain of Custody: Direct handling from collection vehicle to secure wiping and shredding bays.
- Zero Subcontracted Wiping: All NIST 800-88 erasure and physical destruction is executed in-house.
- Licensed WEEE Recovery: Shredded media fractions are processed under our Natural Resources Wales AATF approval (WEE/NR0026WA/ATF).
Frequently Asked Questions
What standards do you follow for data wiping?
We adhere strictly to NIST SP 800-88 Rev. 1 (Clear and Purge guidelines) and current NCSC guidance. This ensures data across enterprise SAS, SATA, NVMe, and flash media is completely overwritten or cryptographically erased beyond forensic recovery.
Do you provide serialised certificates of data destruction?
Yes. Following every clearance project, you receive a formal, serialised Certificate of Data Destruction and an itemised asset report providing complete audit-ready verification for ISO 27001 and UK GDPR compliance.
Are drives processed in-house at an Approved Authorised Treatment Facility (AATF)?
Yes. Sierra Indigo is a UK Approved Authorised Treatment Facility (AATF), approved by Natural Resources Wales (WEE/NR0026WA/ATF). All software sanitisation and physical destruction is performed in-house without third-party brokers, ensuring an unbroken chain of custody and full WEEE compliance for destroyed media.
What happens to drives that fail software erasure or have bad sectors?
Any drive that fails verification or exhibits damaged sectors is automatically quarantined and routed to industrial physical destruction at no additional risk, with its serial number logged as physically destroyed on your final certificate.
Built for Technical & Enterprise Environments
Specialist Hardware Valuation
Unlike general scrap collectors, our engineers understand the true residual value of broadcast racks, server boards, and enterprise storage.
100% Data & WEEE Compliance
Every serial number is tracked from your loading bay through certified data sanitisation and environmentally responsible processing.
Circular Economy First
By harvesting and bench-testing critical spare boards, we keep global infrastructure running while eliminating unnecessary e-waste.
