Mobile media such as USB sticks are important means to support increasingly flexible business and working environments. While devices are shrinking in size and increasing in performance, they are also lost or stolen more easily. Removable Device Encryption ensures that the data cannot be used by unauthorized parties. Password-based encryption and decryption can be achieved on any Windows computer, with full transparency for authorized users. Encryption is file-based, and various encryption types are available (for the whole company, for individual users or for certain user groups). It is possible to use multiple encryption types for one medium.
