Secure Network Foundation 1.1 Design Guide for
Single Site Deployments
Single Site Deployments
This document provides a simple vision for a smart and secure business where everyday communications
are made easier, faster, and more efficient. Cisco partners and resellers can help small-to-medium size
businesses leverage the full value of their data networks by deploying reliable secure routers and
switches from Cisco Systems that are easily provisioned and managed via the use of simple graphical
user interface (GUI) tools. The validated design guidance provided in this document and the validated
implementation guidance covered in the Secure Network Foundation Implementation Guide for Single
Site Deployments (EDCS-517888) provide a verified reference, ensuring that the individual components
that the system is composed of work well together.

Note
The design described in this document is based on a simplified and cost-effective approach to
establishing a secure network foundation as the initial phase of a network evolution. The redundancy in
LAN and WAN design is a mandatory attribute of a resilient network. A resilient network is
recommended for any network that transports mission-critical traffic. This aspect of LAN and WAN
design will be documented in a subsequent release of the validated design. In the meantime, contact your
Cisco representative if you have any questions.
