Secure Your Data


Protect sensitive data

Kryptel encrypts confidential or private files so that they can’t be accessed without the right password or key.

Create protected backups

Unlike ordinary backups, Kryptel-produced ones are encrypted and can safely be stored anywhere, even on a public Web drive.

Take it along

Kryptel can run from an external drive or a USB flashstick.

Silver Key

Send securely

Silver Key encrypts user data and creates an encrypted parcel, which can safely be sent over the Internet. The parcel may contain a file, a group of files and folders, or just a confidential message.

Exchange safely

With Silver Key you can securely transfer files between your PC desktop and your Android device, or exchange files within a workgroup.

Simple and easy

Encrypt and upload a file with a single click. Double-click the received parcel to decrypt it back.
