This IDC study is one of several documents in which IDC presents the results of its annual U.S. WAN Manager Survey. This document presents the company size segmentation view of U.S. medium-sized and large businesses' perspectives on managed network services.

Melanie Posey, program manager for IDC's Web Hosting Services program, says, "Current use of managed networks services is directly proportional to company size. While there is considerable scope to expand penetration in the large enterprise segment, the medium-sized business market (particularly the smaller companies in this segment) represents a relatively untapped market."
