Data Security & Secure Data Destruction Services

Cornerstone Technologies uses state-of-the-art equipment and certified processes to provide complete, irreversible data sanitization and destruction. When upgrading technology infrastructure or retiring end-of-life equipment, protecting sensitive data is critical. We eliminate the risk of data breaches, identity theft, and regulatory non-compliance for government agencies, school districts, and private businesses nationwide.

What Is Data Sanitization?

Data sanitization is the deliberate, permanent, and irreversible removal or destruction of data stored on a memory device. Once sanitized, the device contains no usable residual data and cannot be recovered using any known method.

Our methods include:

• Software-based overwriting with certified utilities
• Hardware-based erasure devices
• Physical destruction of media when required

On-Site Data Destruction & Sanitization

Cornerstone Technologies performs all data sanitization, purging, and destruction on-site whenever requested. We handle all types of media in compliance with NIST Special Publication 800-88 Rev. 1 guidelines, including but not limited to:

• Solid State Drives (SSDs)
• Hard Disk Drives (HDDs)
• Cell phones & smartphones
• USB flash drives & memory cards
• CDs, DVDs, Blu-ray discs
• Magnetic tapes & cartridges
• Zip disks, floppy disks
• Server & enterprise storage

Our Data Destruction Methods

We follow the highest standards, including:

• Active@ KillDisk Enterprise Edition – Three-pass overwrite using random characters, complements, and random data streams (meets DoD 5220.22-M and NIST 800-88)
• Physical destruction – PD-4 Hard Drive Destroyer impales platters when overwriting is not sufficient or when requested
• Degaussing – For magnetic media requiring complete erasure

All failed or non-reusable drives are physically destroyed after circuit board removal to ensure no data recovery is possible.

Protecting Privacy & Regulatory Compliance

Cornerstone Technologies remains fully compliant with all applicable national and state/provincial laws, including:

• Health Insurance Portability and Accountability Act (HIPAA)
• Gramm-Leach-Bliley Act (GLBA)
• Identity Theft Penalty Enhancement Act (ITPE)
• NIST Special Publication 800-88 Rev. 1 (Media Sanitization)
• DoD 5220.22-M standards

Secure Facility & Chain-of-Custody

All data-bearing devices are processed in a controlled-access, fenced, and caged secure area under 24-hour audio and video surveillance. Only fully background-checked and vetted personnel are permitted inside. We maintain strict chain-of-custody documentation from intake through final destruction.

Proof of Destruction

Every client receives a detailed certificate of data destruction, including:

• Serial numbers and asset details
• Method of sanitization/destruction used
• Date, time, and technician information
• Digital audit trail and photographic evidence when required

We validate our processes through regular internal reviews, independent audits, and data recovery attempts on sample sanitized media to confirm zero recoverable data.
