Cisco Small Business Router C881-K9 With Advanced Security For Remote Connectivity

The Cisco 881 (C881-K9) is a compact and cost-effective Cisco Integrated Services Router (ISR), designed specifically for small businesses, enterprise teleworkers, and small branch offices. It offers a secure all-in-one solution that combines Internet access, comprehensive security, and various network services into a single, easy-to-manage device. While not a Cisco Network Switch or Cisco Wireless AP on its own (though some 881 models did integrate Wi-Fi), it provides the essential routing and security foundation for these components in a compact setting.

Integrated Security for Peace of Mind

The C881-K9 router provides robust security features, including an integrated stateful inspection firewall, IPsec VPN capabilities (supporting up to 20 tunnels), and optional content filtering. These features protect sensitive business data and communications over broadband connections, ensuring secure remote access for teleworkers.

Reliable Broadband Performance

Equipped with a Fast Ethernet WAN port and a built-in 4-port 10/100 Fast Ethernet managed switch, the C881-K9 delivers reliable broadband speeds for concurrent data, voice, and video services. Its performance is optimized for small office environments, allowing for smooth operation of essential business applications.

Compact Design & Simplified Management

The router features a compact, fanless desktop design, making it suitable for quiet office environments. Setup and deployment are simplified through web-based tools like Cisco Configuration Professional, allowing for easy management even by users without extensive IT expertise.

Versatile Connectivity for Small Offices

The C881-K9 is a versatile platform that can provide essential routing for a small network. It can connect directly to your ISP for Internet access and provides local area network (LAN) ports to connect computers or a Cisco Network Switch for additional wired devices. For wireless connectivity, it can seamlessly integrate with external Cisco Wireless AP devices, creating a complete network solution for small deployments.
