Cisco Part Number: C8355-G2 is a Cisco 8300 Secure Router with 4x10GE, 4x5GE, 2x1GE, and 1xPIM

The Cisco 8300 Series Secure Routers deliver high-performance, platform-level security and flexible deployment options for large branches and edge locations. Built on a dedicated secure networking processor and the unified Cisco secure networking platform, the 8300 Series combines routing, SD-WAN, and next-generation security into a single, hardware-accelerated appliance to simplify operations and future-proof branch infrastructure.

Key features

Hardware-accelerated security and networking: dedicated secure networking processor for fast cryptography and deep packet inspection, ensuring high throughput with robust threat protection.
Integrated branch connectivity: NGFW, routing, and SD-WAN unified on one platform to reduce appliance sprawl and simplify management.
Post-quantum readiness: support for quantum-resistant cryptography to help future-proof sensitive communications.
AI/ML offload: hardware acceleration for AI and ML tasks to speed analytics and threat detection.
Fanless option: available fanless SKU for quiet deployments and reduced maintenance in noise-sensitive sites.

Models & performance

C8375-E-G2 (modular) — modular platform with expansion slots and flexible WAN/LAN modules; typical forwarding: up to 38 Gbps; IPsec up to ~20 Gbps.
C8355-G2 (fixed) — fixed 1U form factor with multi-gig RJ45 and 10G SFP/SFP+ ports; similar forwarding and IPsec performance, optimized for large branch deployments.

Use cases

Secure routing and SD-WAN for thousands of users and devices.
High-throughput connectivity for bandwidth-intensive applications (voice, video, cloud services).
Network segmentation and compliance-focused deployments.
Mission-critical sites requiring advanced threat protection and durable hardware.

Why choose the 8300 Series

Organizations choose the Cisco 8300 Series when they need consolidated branch functionality — proven routing, SD-WAN, and enterprise-grade security — delivered with hardware acceleration, modular expandability, and operational flexibility (on-premises, infrastructure-as-code, or cloud management).
