The appliance gathers data at a rate of about 50 kilobytes per user per day which equates to upwards of 100GB of compressed recordings for a 5000-employee organization over six months.

Upcoming versions of Intellinx will support client/server and Web traffic.

Intellinx will be sold and integrated locally by Advent One. Bob Bassat from Avent One said the product is non-invasive and does not degrade performance.

"It's aimed at internal users and it protects privacy, fraud, and inappropriate behavior," Bassat said, adding that the device is tamper proof and can perform real-time alerts.

In terms of cost, Basset said a large 'big four' bank would be looking at up to A$700,000 (US$515,396) for a fully deployed system, including the hardware, but a more modest implementation is likely to be about A$100,000 fully deployed.
