Cisco 900 Series Routers: Secure, All-in-One Connectivity for Branch Offices

In today's distributed enterprise, your small branch offices and remote sites are critical gateways to your business—and prime targets for cyber threats. Juggling separate devices for routing, switching, and security is complex, costly, and creates vulnerabilities. You need a simple, powerful, and secure solution that just works.

Enter the Cisco 900 Series Integrated Services Routers (ISRs). These compact, high-performance routers are engineered specifically for small branch offices and managed service provider deployments. They consolidate best-in-class routing, switching, and comprehensive security into a single, easy-to-manage device. Protect your network from known and emerging threats while delivering the reliable, high-speed connectivity your business demands.

Engineered for Performance and Peace of Mind

The Cisco 900 Series ISR is more than just a router; it's a complete networking foundation for your remote sites. Built on the power and flexibility of Cisco IOS Software, it delivers enterprise-grade capabilities in a compact form factor. With hardware-accelerated IPsec VPN performance reaching up to 250 Mbps, you can ensure secure, high-speed communication between your headquarters and branch locations without compromise.

Flexibility is at the core of the 900 Series. Choose from a range of models featuring dual Gigabit Ethernet, VDSL2/ADSL2+, or integrated CAT4 LTE WAN connections. This enables you to build resilient networks with dynamic failover, ensuring business continuity even if a primary connection fails. Every router also includes an integrated 4-port managed Gigabit Ethernet switch, simplifying your local network setup and reducing hardware footprint.

Key Features & Capabilities:

  • Integrated Security Suite: Defend your network with a built-in zone-based policy firewall, intrusion prevention (IPS), and application-aware security to stop threats at the edge.
  • High-Performance VPN: Leverage hardware-accelerated encryption for secure site-to-site connectivity using FlexVPN, DMVPN, and GET VPN, protecting your sensitive data in transit.
  • Redundant WAN Connections: Ensure maximum uptime with support for multiple WAN links and dynamic failover protocols like VRRP and HSRP for seamless business continuity.
  • Built-in Managed Switching: Connect local devices directly with an integrated 4-port Gigabit Ethernet switch, complete with 802.1Q VLAN support for network segmentation.
  • Advanced QoS: Prioritize critical application traffic like voice and video with powerful Quality of Service (QoS) features, ensuring a smooth user experience.
  • Simplified Management: Manage your devices remotely and at scale using familiar tools like the command-line interface (CLI), web-based UI, and Cisco Configuration Professional.
  • Application Visibility: Utilize Network-Based Application Recognition (NBAR2) to identify and control application traffic, optimizing network performance and enforcing policies.

Frequently Asked Questions (FAQs)‍ about Cisco 900 Series Integrated Services Routers

Q: What is the ideal user count for a Cisco 900 Series router?

A: The Cisco 900 Series ISRs are specifically designed and recommended for small branch offices and remote sites with up to 50 users, providing robust performance for typical business applications and secure connectivity.


Q: Can I get a Cisco 900 Series router with 4G LTE for backup?

A: Absolutely. The series includes several models with integrated CAT4 LTE (e.g., C921-4PLTEGB, C927-4PLTENA). This is an excellent solution for wireless WAN failover to ensure business continuity or for primary connectivity in locations without reliable wired broadband. Contact Nexus ITX to identify the correct LTE model for your region.


Q: Can the memory (DRAM) or storage (flash) be upgraded later?

A: No, the Cisco 900 Series routers are fixed-configuration devices. They come with 1 GB of DRAM and 2 GB of flash memory, which cannot be upgraded. It's important to size the solution correctly from the start, and our experts at Nexus ITX can help you do just that.


Q: What kind of security features are included out of the box?

A: The base IP Base license includes essential security features like a zone-based policy firewall and VPN capabilities. For advanced threat defense, including Intrusion Prevention (IPS), you will need the Security (SEC) license. We can help you determine the right licensing for your security requirements.


Q: How do you manage this router? Is it difficult?

A: Management is very flexible. You can use the industry-standard Cisco IOS command-line interface (CLI) for granular control, a user-friendly web-based GUI for simplified setup, or centralized tools like Cisco Configuration Professional. This makes it suitable for teams with varying levels of technical expertise.
