SpyProof!: An Intelligent Encrypted Virtual Disk


Concerned about the security of your sensitive data but find file encryption too time consuming? Imagine a virtual disk drive (implemented as a Windows device driver) that automatically encrypts all data written to it and transparently decrypts that data for any application as long as the disk is mounted. Once unmounted, the encrypted disk is completely unreadable by unauthorized users… and thieves. That’s SpyProof!

Virtual Disk Encryption

SpyProof! enables users to create and manage encrypted virtual
disks that provide transparent data encryption. Users must authenticate in order to ‘mount’ encrypted disks and make the contents accessible. To authorized users and applications, SpyProof! disks appear as additional drives; unauthorized users see only random data.

Virtual Disk Encryption is performant!

  • users do not notice a performance change
  • system boot and application load times are unchanged as these system components are not encrypted

Use Cases for SpyProof!

Encrypting Data at Rest
Protect laptop computers and physically unsecured desktops and servers from security breaches due to loss or theft

Encrypting Backups
Easily create encrypted backups; backup the encrypted SpyProof! data files even when the disks are mounted (live backup of in use disks)

Securing Network Storage
Provide secure network storage for users; users can store an entire SpyProof! disk on a network server and only they and their authorized managers, not system administrators, can access the data

Compartmentalizing Data
Enable data compartmentalization by giving users an administratively inaccessible storage pool
