Product Overview

Hardware-Accelerated Security

Powered by Cisco's secure networking processor, delivering 5 Gbps IPsec and 1 Gbps threat protection with NGFW, IPS, URL filtering, and AMP.

Fanless & Compact

The smallest 8200 Series router with fanless desktop design enables deployment in noise-sensitive environments without compromising performance.

Mixed-Speed Ports

2x 10G SFP/SFP+ WAN ports, 4x 2.5G Multigigabit RJ-45 ports with PoE+, and 4x 1G RJ-45 LAN ports for flexible branch connectivity.

Post-Quantum Ready

PQC-ready architecture protects data today while preparing for future quantum computing threats with hardware-level cryptographic support.

Flexible Management

Manage via Cisco IOS XE CLI, Catalyst SD-WAN Manager, or cloud. Supports infrastructure-as-code for automated deployments at scale.

SD-WAN Integrated

4 Gbps SD-WAN throughput with IPsec, QoS, deep packet inspection, and Flexible NetFlow for dynamic path selection and application optimization.

Features and Benefits

Secure networking simplified in the most compact form factor.

The C8231-G2 delivers robust platform-level security and advanced performance engineering in the smallest, most cost-effective 8200 Series package with no module support required.

19 Gbps Forwarding

Hardware-accelerated forwarding at 19 Gbps (512B) ensures wire-rate performance for routing and SD-WAN workloads.

Integrated NGFW

1 Gbps threat protection with NGFW, IPS, URL filtering, and AMP eliminates the need for separate security appliances.

Fanless Design

Silent operation makes it ideal for open offices, retail counters, and healthcare environments where noise is a concern.

Most Compact

At just 1.14 x 8.1 x 12.23 in and 5 lbs, the C8231-G2 is the smallest 8200 Series router for space-constrained branches.

5 Gbps IPsec

Hardware-accelerated encryption delivers 5 Gbps IPsec throughput for secure site-to-site and remote access VPN tunnels.

Cost-Effective

Fixed configuration with no module support delivers essential routing and security at the lowest entry point in the 8200 Series.
