Cisco 4221 Integrated Services Router

Meet all your branch needs with one device

As you build out the digital capabilities in your enterprise branch offices, consider the full-service sophistication of the Cisco^® 4000 Series Integrated Services Routers (ISR 4000). The ISR 4000 Series consolidates many must-have IT functions, including network, security, compute, storage, and unified communications. You get everything you need in a single platform. That means significant savings in capital, operational, and management expenses for lower total cost of ownership.

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. The ISR 4000 Series includes Cisco Trust Anchor Technologies that help mitigate modern cyberattacks by verifying platform integrity and providing protection from counterfeit and unauthorized modification of hardware and software. The 4000 Series contains seven platforms: the4461, 4451, 4431, 4351, 4331, 4321, and 4221.

Benefits

Easily grow your branch offices with these industry-leading router capabilities:

• Ability to extend intent-based networking to the WAN and enable policy-based automation by deploying Cisco^® SD-WAN.
• Modularity, providing a range of WAN access connectivity options such as 3G/4G/LTE and readiness for 5G, switching, compute (Cisco UCS^® E-Series), unified communications, and storage integrated into a single form factor to provide the capabilities of a complete branch in one box.
• Enhanced full edge security with Cisco Umbrella^® Secure Internet Gateway (SIG), trustworthy systems, and Encrypted Traffic Analytics, protecting against modern cyberattacks as well as counterfeit and unauthorized modification of hardware and software.
• Scale and performance using multicore processing, providing gigabit performance while multiple services run concurrently.
• Effective license management, allowing you to pay as you grow.
• Auto-configuration of Cisco Intelligent WAN features to help deliver SD-WAN to enterprise networks.

Intelligent services reduce bandwidth costs

The ISR 4000 Series runs Cisco SD-WAN, a comprehensive set of traffic control and security features. With Cisco SD-WAN, you get all the business-grade capabilities of a Multiprotocol Label Switching (MPLS) VPN using other types of less-expensive links. You get per-application traffic management, WAN optimization, and VPN tunneling, for example, which you can put to work across internet, cellular, and other lower-cost services as you add connections. And you can activate new router services on demand through a simple licensing change.

The ability to install and manage applications remotely means you don't need local IT staff to deliver a fully comprehensive computing and networking experience in the branch. That comes in handy at new or smaller sites where you don't have IT personnel already. All this plus convergence and stable, high-speed performance means you can roll out your branch services at the speed of business.

SD-WAN configuration

With the ISR 4000 Series, you can configure your Cisco SD-WAN features in next to no time, thanks to Cisco's Software-Defined Networking (SDN) controller, the Cisco vManage application. vManage sits in the cloud and automates a number of tasks across the network.
