Which Cisco router suits a small branch office?
An ISR 1100 covers most small branches, with an LTE or 5G variant if you want cellular backup built in. If the site runs voice gateways or several service modules, an ISR 4000 is the better fit.

Overview
Cisco Routers — ISR, Catalyst 8000 and Branch WAN Supplier
We supply Cisco branch and edge routers for sites that need more than a broadband box — dual circuits, VPN back to head office, SD-WAN policy or a 5G failover path. We size on the WAN bandwidth and the services running over it, not the interface count.

Cisco router models we quote most
Branch routing splits by throughput and by whether you want classic IOS-XE routing or SD-WAN. We quote both paths and explain the licensing difference before you commit.
- ISR 1100 series — small branches, integrated LTE/5G options, fanless
- ISR 4000 series — mainstream branch routing with voice, security and WAN modules
- Catalyst 8200 / 8300 — modern branch edge with SD-WAN and cloud on-ramp
- Catalyst 8500 — regional hub and data-centre WAN aggregation
| Deployment | Typical site | WAN profile | Notes |
|---|---|---|---|
| ISR 1100 | Small branch, retail, remote site | Up to a few hundred Mbps, optional LTE/5G | Fanless, wall or shelf mount |
| ISR 4000 | Established branch with voice and security services | Gigabit-class with service modules | Modular NIM slots, UC gateway capable |
| Catalyst 8300 | Branch edge moving to SD-WAN | Multi-gigabit, dual circuit, cloud on-ramp | IOS-XE SD-WAN, DNA licensing |
Dual circuits, VPN and 5G backup
Most router enquiries we take are really resilience enquiries. We design the WAN so a failed circuit is a non-event — dual providers, automatic failover, and policy that keeps voice and line-of-business traffic on the healthier path.
- Dual-WAN failover with fibre, broadband and 5G backup
- Site-to-site and remote-access VPN terminated on the router
- SD-WAN policy for voice, Teams and business applications
- Cellular modules and antennas quoted with the router
Licensing and support without surprises
Cisco routing licences are where budgets slip. We set out the DNA tier, the term and the renewal date in writing, and co-terminate multi-site estates so everything lands on one anniversary.
- DNA Essentials and Advantage explained against what you actually use
- SmartNet support tiers with defined replacement terms
- Co-terminated renewals across branch estates
FAQs
Questions We Are Asked Most
Should I buy an ISR or move to Catalyst 8000 SD-WAN?
If you are managing a handful of sites with static routing and VPN, an ISR is simpler and cheaper. Once you have multiple circuits per site or a dozen-plus branches, Catalyst 8000 with SD-WAN pays for itself in central policy control.
Can you configure the router before delivery?
Yes. We pre-stage interfaces, routing, NAT, VPN tunnels and QoS, then ship it ready to connect, with the running configuration documented for your team.
