SOLUTION PROVIDESTHE SIMPLICITY EVERY BUSINESS NEEDS.

Integrated, end-to-end security—To safeguard confidential

business data, a Cisco network provides enhanced security that

protects the network from internal and external threats.

An integrated security solution also simplifies security

management and greatly reduces the total cost of ownership

of the network.

High network availability—A Cisco network helps ensure the

reliable network access and maximum uptime that companies

depend on to support new users, open new offices, deploy new

services, extend their networks to customers and partners,

support a more mobile workforce, and more. Cisco switches and

routers include support for network and link redundancy, dynamic

routing, automatic failover, and redundant power for improved

fault tolerance and network availability.

Predictable performance—Intelligent end-to-end management

maximizes the availability and performance of critical applications.

Cost-conscious small and medium-sized businesses (SMBs) can

maximize WAN bandwidth to serve more users and conduct

more business over

the Internet without upgrading to more

expensive WAN facilities.

Ease of use—Cisco’s intuitive end-to-end Web-based management

helps keep administrative expenses down—even as the network

expands.

Cost-effectiveness—An end-to-end solution approach reduces

complexity and network management costs. Modular and

scalable products help reduce costs of future expansion.

Investment protection—Customers can receive trade-in value

for existing Cisco products against the purchase of new Cisco

products.
