The Cisco ISR4331/K9 is a 1U rack-mountable, modular Integrated Services Router from the Cisco ISR 4000 Series (launched 2013–2014). It is a mid-range branch router designed for medium-sized businesses, branch offices, and distributed enterprise WAN edge deployments requiring advanced routing, security, SD-WAN, voice, and application optimization in a compact, high-performance platform.

The ISR4331/K9 is a 3-port Gigabit Ethernet router with modular expansion capabilities. It combines routing, security, voice, and application services into a single 1U chassis. Key features include:

• 3 onboard Gigabit Ethernet RJ-45 ports (GigabitEthernet0/0/0, 0/0/1, 0/0/2) — configurable as LAN or WAN interfaces
• 2 NIM slots (Network Interface Modules) for expansion (e.g., T1/E1, serial, ISDN, LTE, voice, additional Ethernet)
• 1 SM-X slot (Service Module slot) for higher-density modules (e.g., SM-X-72FXS/DID voice module, SM-X-64FXO, UCS-E server blades)
• 1 ISM slot (Internal Service Module) for optional security/acceleration cards (e.g., ISM-VPN)
• Dual redundant power supply bays (default single PSU; optional second for redundancy)
• Redundant hot-swap fans (front-to-back airflow)

It runs Cisco IOS XE with modular software licensing:

• IP Base (default) — basic routing, security, QoS
• Upgradable to Security, UC (Unified Communications), AppX (Application Experience), or full UC license bundles

Common deployment scenarios:

• Branch office WAN router with MPLS/Internet breakout
• DMVPN hub/spoke or GETVPN
• Voice gateway (SRST, CME, CUBE)
• SD-WAN edge (with Viptela vManage/IWAN)
• Application visibility & control (AVC, NBAR2)

The "K9" in the part number indicates the crypto-enabled version (IPsec VPN support).
