For the highest security requirements, we physically destroy storage media at the hardware level. Degaussing and drilling available on-site. Shredding performed at our certified facility per regulatory requirements.
High-intensity electromagnetic field permanently destroys all data on magnetic media in seconds. Meets NSA/CSS specifications for magnetic degaussing. No physical contact required; drives remain visually intact but data is irrecoverable.
Industrial-grade hydraulic punch physically perforates drive platters at multiple points, rendering data unrecoverable. Destruction is visible to the naked eye, ideal for compliance demonstrations and audit requirements.
High-torque multi-stage industrial shredder reduces entire drives, including platters, PCBs, and enclosures, to uniform particles approximately 1 cm in size. Complete physical destruction meeting the highest security standards.
Our operations are governed by the world's most rigorous compliance frameworks, ensuring your organization meets every regulatory requirement.
