most comprehensive security services
embedded within the router that can be enabled
with a Cisco IOS Security Image. This provides
customers with a single, resilient platform to
rapidly deploy secure networks and applica-
tions. The Cisco 1800 Series was designed with
integrated security to provide a tight coupling
among security, routing, and other integrated
services throughout the network. With a Cisco
IOS Software-based VPN, fi rewall, and intrusion
prevention system (IPS), as well as optional
enhanced VPN acceleration, and network

defense, the Cisco 1841 offers a robust and
adaptable security solution for branch-offi ce
routers. Every Cisco 1800 Series router comes
with the factory-installed Cisco Router and
Security Device Manager (SDM). Cisco SDM is
an intuitive, Web-based device manager that
offers easy router confi guration and monitoring,
startup wizards for quick deployment and lock-
down, smart wizards to help enable security
and routing features, Cisco Technical Assistance
Center (TAC)-approved router confi gurations,
and subject-related educational content.
Integrated Services
By providing integrated services, as well as
great modular density and high performance,
the Cisco 1841 router provides security,
versatility, scalability, and fl exibility for multiple
applications to the small-to-medium-sized
business, small enterprise branch offi ce, and the
service provider customer edge. The Cisco 1841
router easily accommodates several network
applications, such as secure branch-offi ce data
access (including NAC for antivirus defense),
VPN access and fi rewall protection, business-
class DSL, IPS support, inter-VLAN routing,
and serial device concentration. The Cisco 1841
router provides customers with the industry’s
