D-Secure File Eraser vs ZERDAVA File Shredder

D-Secure File Eraser overwrites file data at the sector level with the aim of making it unrecoverable. It can target files and folders, unallocated space and MFT data, cached cloud-sync copies, network shares, archives and full volumes. The product lists more than 27 sanitization algorithms, including NIST Clear/Purge, DoD, Gutmann, HMG IS5 and RCMP standards. Erasure jobs can run through CLI or REST API, webhooks, Windows Task Scheduler, cron and Group Policy hooks. Administrators can remotely execute and monitor jobs across endpoints with the Cloud Console. Each erasure produces a digitally signed PDF report containing a file hash, algorithm, pass count, operator ID and UTC timestamp; the maker also describes WORM-compliant audit logs. It says AES-256-CBC encryption is applied before overwriting, and interrupted erasures leave data cryptographically inaccessible. Windows, macOS and Linux are supported. The annual subscription starts at $40 a year, and a 30-day trial is available; there is no free plan.

ZERDAVA File Shredder securely erases files, folders, disks and removable media on Windows and Android. Its free-space wipe targets unused disk space, and it can erase USB sticks and SD cards. Before deletion, the product checks a password; afterward, it can generate a report. ZERDAVA says its software supports more than 20 international erasure standards, though available methods vary by version; Gutmann is the listed standard. The Windows Shredder plan costs $26 a year and includes a 7-day free trial. The Android Mobile Shredder plan also has a 7-day trial, but no price is listed. Supported systems listed in the FAQ are Windows 7, 8, 8.1 and 10, and Android 4.1 or higher. Windows downloads include online and offline installers in 32-bit and 64-bit versions, with English and Turkish options. Automatic updates are provided during the license period. For organizations, ZERDAVA describes solutions for servers and workstations, with a web-based management console in its enterprise solution. Its privacy policy says offline-scanned personal data stay on the device, while files with suspicious clues may be sent to its cloud service for examination.
