The Cisco ISR4331/K9 is part of the Cisco 4000 Series Integrated Services Router range, built to handle branch office routing, security and voice services on a single platform. Running Cisco IOS XE, it supports a wide range of services including site to site VPN, firewalling, WAN optimization and voice gateway functions, reducing the number of separate boxes needed at a branch site. Its modular design allows different WAN interface cards to be fitted depending on the connection type available at a site, whether that is fiber, copper broadband or a leased line, giving flexibility as connectivity options change over time. Antofity Concepts supplies and configures the ISR4331/K9 for organisations in Kenya with branch offices that need enterprise grade routing, security and voice services in one device.
