Cisco Integrated Service Routers Generation 2 (ISR G2)
Cisco 3900, 2900, and 1900 Series Integrated Services Routers (ISR) build on 25 years of innovation and product leadership. Cisco Integrated Services Routers Generation 2 (ISR G2) are architected to enable the next wave of branch-office evolution, enabling richer media experiences with video, and local compute resources for local application flexibility and survivability. Adding to the rich breadth of services available on the original ISRs – security, unified communications, wireless, and application optimization services – the ISR G2 routers enhance the reduction in overall branch-office expenses with the introduction of flexible services “on demand” through software licensing and simplified Cisco IOS Software packaging.
As part of the available security services, Cisco Firepower Threat Defense for ISR provides the industry-leading threat protection for the entire network surface areas as part of the Cisco Intelligent WAN (IWAN) deployment for hybrid WANs and direct Internet access. With Cisco Firepower services, the ability to detect anomalies, enforce policy, and accelerate mitigation is now built into the ISRs. By using existing ISR G2 and the Cisco 4000 Integrated Services Router, customers gain continuous visibility and control to defeat malware across the extended network and the full attack continuum: before, during, and after an attack.
The ISR G2 portfolio consists of three product families similar to the first generation of ISRs: the Cisco 3900, 2900, and 1900 Series Integrated Services Routers. From the Cisco 1921 through the Cisco 3945E, the portfolio provides increasing performance, module slot density, and features to match the needs of diverse branch offices running varying degrees of rich services.
