ISR4221/K9 Integrated Service Router Description
The Cisco ISR4221/K9 is a member of the Cisco 4000 Series Integrated Service Routers that provides easy routing, security, hosting, and switching in one single compact device. The ISR4221/K9 router adopts advanced technologies such as enhanced application visibility, edge computing, and SD-WAN while meeting heavy network performance requirements driven by cloud applications and digital transformation.
Cisco SD-WAN:
Cisco Software-Defined WAN (SD-WAN) is an intelligent software service that allows users, devices, and office branches to connect reliably and securely across a diverse set of WAN transport links. The SD-WAN is supported on the ISR4221/K9 router, delivering dynamic route traffic across the best connection for a great application experience.


Simplified Management:
The ISR4221/K9 network and enforcement business policies can easily be configured and monitored through Cisco DNA Center and Cisco SD-WAN. This simplifies network automation.
Threat Protection:
Cisco ISR4221/K9 offers advanced protection of your branch site across the WAN/LAN and in the cloud with security integrated into the router.
