It has installed the WS1000 gateway appliance from Sophos at its Portsmouth datacentre to provide 5,000 staff working on its European wide area network with secure internet access.
Chris Leonard, European IT security and compliance manager at Heinz, said the firm decided to use the integrated web browser included with the thin client terminals after finding that running web browsing off its datacentre servers was putting too big a load on them.
This was due to the need to run a copy of Internet Explorer for every user.
Leonard said he wanted to use the thin client's built-in web browser to overcome this, but needed to prevent the device from spreading a worm on the company's network.
"The WS1000 gateway appliance checks all web traffic and updates virus signature files over the internet, making safe browsing possible," he said.
Heinz is also using Sophos Anti-Virus's application control feature, which allows businesses to restrict use of unauthorised or unwanted applications.
