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.
