The Cisco 4221 ISR is everything you need in a single platform: the digital-ready platform consolidates many must-have IT functions, including network, security, compute, storage, and unified communications. This not only simplifies day-to-day IT management, but it also means significant savings in capital, operational, and management expenses for lower total cost of ownership. The ISR4221/K9 is the basic modular platform, and it is upgradable so you can increase capabilities and functions with added modules.
Cisco Intelligent WAN (IWAN)
Cisco IWAN is a set of intelligent software services that allow you to reliably and securely connect users, devices, and branch office locations across a diverse set of WAN transport links. IWAN-enabled routers like the 4000 series dynamically route traffic across the "best" link based on up-to-the-minute application and network conditions for great application experiences. You get tight control over application performance, bandwidth usage, data privacy, and availability of your WAN links - control that you need as your branches conduct greater volumes of mission-critical business.
Cisco converged branch infrastructure
The Cisco 4000 series ISRs consolidate many must-have IT functions, including network, compute, and storage resources. The high-performance, integrated routers run multiple concurrent IWAN services, including encryption, traffic management, and WAN optimization, without slowing your data throughput. And you can activate new services on demand through a simple licensing change.
