Why You Choose Cisco ISR 4000 Series Router Today?
Meet All Your Branch Needs with One Device
Intelligent Services Reduce Bandwidth Costs
Near-Instant IWAN Configuration
What Else? Prepare your branch site and protect it for the future with the Cisco 4000 Series ISR digital-ready platform now.
The Cisco ISR 4000 Series routers consolidate many must-have IT functions, including network, security, compute, storage, and unified communications. So you get everything you need in a single platform. The platform is modular and upgradable, so you can add new services without changing equipment. It supports multiple application-aware services concurrently while maintaining WAN performance of up to 2 Gbps, even during heavy traffic loads.
The backplane architecture supports high-bandwidth, module-to-module communication at speeds up to 10 Gbps.
██ Highlights
- Cisco IOS Universal Image (IP Base/SEC/UC/AX)
