AndroidiShredder™ Windows Server securely overwrites files, folders, partitions, free space, and RAID volumes directly on Windows Server. No reboot required. Includes up to 23 erasure methods, CLI automation, and signed audit reports.
What normal deletion leaves behind
Windows usually removes only the file-system reference. Data remnants can remain in unallocated sectors, shadow copies, cache files, and paging areas until they are deliberately overwritten.
What iShredder Server delivers
From live erasure to signed reporting, iShredder Server goes beyond conventional deletion tools.
Runs directly on Windows Server and erases selected data without restarting the server.
Server includes 11 methods; Military Server extends this to 23, including methods based on DoD, NATO, BSI, NIST, and Protectstar ASDA.
Supports standard Windows volumes, hardware and software RAID, external server drives, and USB backups.
Documents volume, method, passes, bytes, timestamps, operator, and verification. Digitally signed for tamper-evident documentation.
Built for PowerShell, batch jobs, schedulers, and recurring erasure workflows.
Overwrites data remnants in free space, the Recycle Bin, temporary files, paging areas, and browser caches.
Live on Windows Server
iShredder Server runs as an application on Windows Server. Files, folders, partitions, and free space can be overwritten without restarting the machine. Services and workloads continue running as long as they are not accessing the data currently being erased.
The proof
Normal file deletion usually removes only the reference. iShredder overwrites the affected areas and documents verification in the report.

Up to 23 recognized erasure methods
Server includes 11 methods; Military Server includes up to 23. The right edition depends on your policy: GDPR and ISO evidence, government audits, defense standards, or internal requirements.
NIST SP 800-88 Rev. 2 was published on September 26, 2025, and replaces Rev. 1. iShredder maps NIST-related methods to the procedures currently implemented in the product.

System & Requirements
iShredder Server is delivered as a Windows Server application. Here is an overview of the most important supported operating systems, storage scenarios, and file systems.
Operating Systems
Storage & Interfaces
Data & File Systems
For NVMe drives and modern SSDs, we recommend also using a hardware secure erase provided by the manufacturer whenever available. Effective sanitization on solid-state media also depends on wear leveling and controller behavior.
GDPR & Audit
The GDPR requires personal data to be erased in certain cases and requires controllers to demonstrate compliance with data protection principles. iShredder Server supports this documentation with signed reports covering method, volume, result, timestamp, and operator.
Each report includes typical fields for technical evidence:
Once started, an erasure process is designed for permanent data removal. Volume, path, affected applications, backups, and method should be reviewed carefully before approval.
Licenses & Care Plan
Server for GDPR, ISO, and government audits. Military Server for extended military methods. 3-year licenses include the Care Plan with premium support and upgrades.
For ongoing compliance and audit processes: live erasure on Windows Server with 11 recognized methods, signed reports, and CLI automation.
1 year · or US$299 for 3 years with Care Plan
For government agencies, defense, and stricter internal policies: all Server features plus up to 23 methods, including NATO, NAVSO, AFSSI, and CSEC.

Frequently Asked Questions
Server includes 11 methods and covers typical evidence requirements for GDPR, ISO, and government audits. Military Server includes up to 23 methods, including NATO, NAVSO P-5239-26, USAF AFSSI-5020, and CSEC ITSG-06.
If a policy or contract requires one of these standards, Military Server is the right edition. For standard GDPR and ISO 27001 workflows, Server is usually the right edition.
Yes. Server installs as an application on Windows Server and works during live operation. Active workloads, services, applications, and login sessions continue running as long as they do not involve the same files currently being erased.
A file opened by another process is logged in the report as "in use." Once released, it can be erased again, or the operation can be moved to a maintenance window.
Server includes a command-line mode. Paths, method, and report options are passed as arguments and can be integrated into PowerShell scripts, batch jobs, or Windows Task Scheduler. Every operation creates a signed report regardless of how it is launched.
Typical use cases include nightly maintenance windows, scheduled offboarding workflows, regular free-space cleanup, and automated GDPR erasures from a ticketing system.
Server works at the logical level of the Windows file system. Hardware and software RAID arrays are supported as long as Windows sees them as regular volumes. This applies to RAID 1, RAID 5, RAID 6, RAID 10, and common Storage Spaces configurations.
SATA, SAS, SCSI, USB, and iSCSI are supported. NVMe depends on the controller and driver. External server drives and USB backups are treated like regular volumes.
No. As long as Windows is running, parts of the system partition are locked: registry hives, the Master File Table, the paging file, and shadow copies. Server can overwrite files, folders, partitions, and free space, but not the partition on which Windows Server itself is running.
If a server's system drive itself must be erased, for example before device disposal or re-imaging, iShredder™ Technical is designed for that purpose. Technical boots from USB outside the system and can also overwrite the system partition in a verifiable way.
The reports are digitally signed and document host name, volume, path, method, number of passes, bytes, verification result, timestamp, and operator. This allows them to support internal audits, data protection reviews, ISO 27001 processes, and technical evidence requirements.
Whether a report is accepted as evidence in a specific proceeding is decided by the responsible authority. The reports provide the key technical evidence fields for that purpose.
For Audit, IT, and Compliance
iShredder™ Windows Server overwrites data directly on Windows Server and creates signed reports for audits, data protection, and automated IT processes.
