Retain Operating System
Learn how to securely wipe user data and personal files while keeping your Operating System intact for redeployment.
Selective Erasure Overview
D-Secure's selective erasure technology allows you to permanently delete sensitive data, applications, and files while preserving your operating system and essential system files. This approach is ideal for device redeployment, selling, or transferring ownership without the need to reinstall the operating system.

Keep your operating system and essential drivers intact while removing all personal and sensitive data using File Eraser technology.
Time Efficient
Save hours of reinstallation time. Ideal for enterprise ITAD workflows where speed is critical.
