Foundry Networks has built security into its switching infrastructure to help companies deal with the increasing problem of mobile devices and remote users.

A line of new products include SecureIronLS LAN switches and SecureIron Perimeter Traffic Manager. Foundry said the switches are the industry's first with added Layer 2 to 7 security.

As the edge of the network grows more complicated, due to the rollout of mobile, wireless and Web-based access, it has become more important to protect the network's core from the perimeter, the company said. Cisco and Enterasys are also building security into their infrastructure products.

SecureIronLS keeps control of traffic through a three-step process, authenticating user and device credentials, enforcing service rights for each user or device and using packet inspection to scan content at Layer 7. It comes in two models, the LS100 and LS300, with the LS300 delivering better performance. The LS100 is priced from 15,000 euros (£10,000) and the LS300 starts at 35,000 euros (£23,000).

The Perimeter Traffic Manager is a front-end to existing firewalls and performs denial of service protection and packet inspection at the perimeter.
