There is a saying that the sole interest of network engineers is to get things hooked up, to get packets through the pipe. We emphasize a differentiated view: Connectivity starts at the application layer of a computer system, reaches to the application layer of a remote computer, and includes aspects of quality, performance, authorization, authentication, security, and cost.

In the area of IP networking we offer engineering, design, and operation of IP networks based on technology from Cisco and other vendors. Included are aspects of network, system, and gateway security by means of protection techniques such as secure configuration, firewalls, monitoring solutions, and more.
