iKey 4000 PKI Token

Most Advanced USB Authentication Technology

iKey USB 4000

Most Powerful Cryptographic Device Available Today

SafeNet’s industry-leading iKey 4000 is a USB-based portable PKI, two-factor authentication token that provides security for verification, signing, and encryption.

Built with the most powerful cryptographic technology to date, the iKey 4000 is also designed with a new tamper-proof casing that is practically indestructible.

The iKey 4000 is RoHS compliant, and is designed to support a wide range of desktop applications and portable systems. Its low-cost, compact design, and standard USB interface make it easier to deploy than other token options.

Biometric Ready

Match-on-card biometric functionality is available to create an even higher level of security.

Eliminates the Need for Reader Devices

An extension of smart card technology, the iKey 4000 plugs into any USB port of a user’s computer to provide strong user authentication without the need for costly reader devices. Its low cost, compact design, and standard USB interface make it easier to deploy than cumbersome smart cards or one-time PIN devices.
