Israeli vendor Yoggie Security Systems has released its new Gatekeeper Card Pro which helps businesses secure laptops used outside the corporate firewall.

Gatekeeper, which can be slotted into a laptop's ExpressCard slot, acts as " a computer within a computer", Yoggie claimed, providing users with 13 different security applications to protect against threats, including spam, viruses and phishing.

The Gatekeeper Card Pro should significantly free up system resources, said the firm, with the plug-in device eliminating the need for users to install security applications on their laptops.

The cost of the Gatekeeper Card Pro is £99. A USB stick version - the Gatekeeper Pico – is also available at a cost of £75.
