Yoggie Systems’ Gatekeeper Pro, is asmall security appliance that brings corporate-class security applications within the reach of mobile and remote workers. The credit-card-sized Yoggie Personal Security Gatekeeper has two Ethernet ports, and runs sophisticated firewall, VPN, and monitoring software on a hardened Linux kernel.

The Yoggie Gatekeeper Pro is essentially a miniature and robust computer that uses a fully hardened and secure embedded OS with the sole purpose of protecting all operating systems. Connectable via USB, this laptop security solution offers 13 layers of protection and eliminates the need for multiple security applications on an OS that may conflict with each other and reduce computer performance. The technology presents an alternative to the recently introduced OS virtualization implemented by software, as the Yoggie Gatekeeper Pro appliance physically separates security applications from the platform by placing them on dedicated hardware.
