iShredder (formerly Data Shredder) allows for secure deletion of data from hard drives and external data storage devices. The software meets and exceeds government, military and industry standards for the permanent erasure of digital information. It erases all existing data up to top-secret security level data and enables users to efficiently delete their data in such a way as to preclude reconstruction, even by government agencies.

Features:

• Certified Deletion Algorithms Depending on the edition, Data Shredder for Mac® comes with secure deletion algorithms such as DoD 5220.22-ME, US Air Force (AFSSI-5020), US Army AR380-19, DoD 5220.22-M ECE, BSI/VS-ITR TL-03423, BSI-2011-VS, CSEC ITSG-06, NATO Standard, Gutmann, HMG InfoSec No.5, DoD 5220.22 SSD and others. Each algorithm has been analyzed by authorities and independent organizations to make sure it really does what it says on the tin - data destruction beyond redemption.
• Drag and Drop without trace: Data Shredder for Mac offering a high level of user friendliness. With the intuitive drag and drop navigation, users can completely delete data from their hard drives or external data storage devices. Drag and Drop files, folders, hard drives or even external devices to the drag and drop area and securely erase it with just a push of the shred button. Securely wipe the freespace using patented security standards, making it impossible to recover any deleted data.
• Do you know what is still there in your free space? When you delete a file or a photo the operation system just removes the reference to that data, but doesn’t delete the actual files on your memory. It just simply marked as free so that another file can come and use those blocks. With the freespace erase option in Data Shredder for Mac you can wipe the unused disk space securely so that deleted data cannot be recovered.
