Expert guides on data sanitization, compliance requirements, and ITAD best practices.
Deleting files or formatting a drive does not remove data. Data sanitization permanently and irreversibly destroys it. This guide covers the three NIST categories, when to use each, and why documentation is critical.
NIST published the updated SP 800-88 Rev. 2 in 2025, modernizing media sanitization guidance for SSDs, NVMe, cryptographic erasure, and cloud environments. Here is what changed and what your organization needs to do.
Physical destruction and software erasure both achieve compliant data sanitization, but they differ in cost, environmental impact, and asset recovery value. This comparison covers when to use each and why most organizations benefit from a hybrid approach.
HIPAA requires that ePHI be rendered unusable, unreadable, and indecipherable at disposal. This guide covers the specific rules, documentation requirements, penalty tiers, and best practices healthcare organizations need to follow.
A certificate of data destruction is the proof that data was actually destroyed. This guide covers what it should include, red flags in weak certificates, how tamper-evident QR verification works, and why seven-year retention is the standard.
Gaps in your ITAD chain of custody create legal liability, compliance failures, and reputational risk. Learn what proper documentation looks like and how to automate it.
Traditional overwrite methods leave data recoverable on SSDs. Learn why flash storage requires firmware-level sanitization commands and what NIST recommends.
Switches, routers, and firewalls store sensitive data too. Learn how Revoke automates network equipment sanitization and integrates with ExpungeData for tamper-evident documentation.
PCI DSS Requirements 3.1 and 9.4 mandate documented destruction of cardholder data. Learn what QSAs expect and how to produce audit-ready records.
The hidden costs of in-house data destruction -- labor, software, equipment, and documentation gaps -- often exceed third-party services. Here is the true cost breakdown.
