Benefits of Migrating to Cisco ISR 4000 & Comparison of ISR 4000 Models


The 4000 Series ISRs consolidate many must-have IT functions, including network, security, compute, storage, and unified communications. So you get everything you need in a single platform. That means significant savings in capital, operational, and management expenses for lower total cost of ownership. The platform is modular and upgradable, so you can add new services without changing equipment. It supports multiple application-aware services concurrently while maintaining WAN performance of up to 2 Gbps, even during heavy traffic loads. The backplane architecture supports high-bandwidth, module-to-module communication at speeds up to 10 Gbps.

The 4000 Series includes Cisco Trust Anchor Technologies that help mitigate modern cyberattacks by verifying platform integrity and providing protection from counterfeit and unauthorized modification of hardware and software.

The 4000 Series contains five platforms: the 4451, 4431, 4351, 4331, 4321 and 4221 ISRs.

Benefits of ISR 4000 Series

Easily grow your branch offices with these industry-leading router capabilities:

  • Networking, services, computing, and storage integrated into a single form factor
  • Consistent, gigabit performance while multiple services run concurrently
  • Modular Cisco IOS XE Software, which quickly adapts to changing needs
  • Integrated Cisco Intelligent WAN features, including application awareness, quality of service, and WAN optimization
  • SDN-based automation of IWAN feature configuration with IWAN app
  • Pervasive security with VPN options, threat defense services, and consistent policy enforcement
  • Trust Anchor Technologies, protecting against modern cyberattacks, as well as counterfeit and unauthorized modification of hardware and software
  • A range of WAN access connectivity options such as 4G LTE, T1/E1, T3/E3, xDSL, serial, and fiber Gigabit Ethernet Auto-configuration of Cisco Intelligent WAN features helps deliver software-defined widearea networking (SD WAN) to enterprise networks.

What are the differences among the six models of ISR 4000 Series? Cisco also updated the newest model comparison of ISR 4000 series. Let’s take a look.
