Cisco is redefining optimal routing capabilities with new integrated multiservice routers that can securely deliver data, voice and video services. With practice and innovation, the 1800 Series, 2800 Series, and 3800 Series Integrated Multiservice Routers not only deliver the industry's most comprehensive security services, but also intelligently embed data, security, and voice to deliver business-critical applications in a scalable, fast manner. Rich integrated solutions for remote intervention, mobile applications,extranets, service management, and more for small businesses and branch offices of large enterprises.

The Integrated Multiservice Router is capable of interlinking with the 7200 Series, 7301 and 7600 Series Security Routers The 7200 Series and 7301 Aggregation Routers also share operating software with the Integrated Multiservice Router. This enables customers to build truly effective integrated intelligent networks.The 1800, 2800 and 3800 Series Integrated Multiservice Routers, along with the 7200 Series and 7301 Headend Routers, are part of Cisco's self-defense network that helps organizations identify, prevent and respond to network security threats. Leveraging Cisco software-based VPNs, firewalls and IPS, optional enhanced VPN acceleration, intrusion detection systems (IDS) and internal engine network modules, they not only provide the industry's most robust adaptive security solution for branch offices, but also leverage the 7000 platform to provide complementary support at the headend.

Self-defense networks can provide four types of protection for routers:

1：Secure Connection - Provides secure network connections that are easy to expand and contain a variety of traffic, such as VPN,    DMVPN, VRF and MPLS security zones, voice and video VPN(V3PN), and highly secure voice.

2：Adaptive Threat Defense - Prevent and respond to network attacks and threats with network services, including IPS and Cisco IOS Firewall.

3：Trust and Identity - Enables networks to intelligently protect endpoints using technologies such as Network Accreditation Control NAC, identification and authentication, and authorization.

4：Network infrastructure protection - protection against attacks on the network infrastructure, especially at the network level, including control plane supervision CPP, network-based application recognition (NBAR) and AutoSecure
