High-Performance Secure Connectivity – Cisco 921 Gigabit Ethernet Security Router – C921-4P

The Cisco 921 Gigabit Ethernet Security Router – C921-4P is a compact and versatile routing solution engineered for small businesses, retail sites, and branch offices. It combines Gigabit-speed routing, advanced security, and integrated switching into one robust platform. Designed to ensure secure and efficient connectivity, the C921-4P provides all-in-one functionality in a small footprint, minimizing the need for multiple devices at the edge of your network.

 
Integrated High-Speed WAN and LAN Ports – Cisco 921 Gigabit Ethernet Security Router – C921-4P

This router includes 2 Gigabit WAN ports, allowing redundancy or load balancing between internet connections. The 4 Gigabit LAN ports act as a built-in managed switch, providing high-speed access for local devices without the need for an external switch. Whether you're connecting to cloud services, VPN tunnels, or local servers, the C921-4P ensures high throughput across your network.

 
Enterprise-Class Security – Cisco 921 Gigabit Ethernet Security Router – C921-4P

With built-in support for IPsec VPNs, 3DES, and AES encryption, the C921-4P delivers enterprise-grade security to protect sensitive data in transit. Ideal for site-to-site and remote worker VPNs, it supports encrypted tunnels to safeguard communication across public networks. Advanced firewall and access control features further ensure that only authorized traffic reaches your internal resources.

 
Dynamic Routing and Redundancy – Cisco 921 Gigabit Ethernet Security Router – C921-4P

This router supports multiple failover and redundancy protocols, including VRRP (RFC 2338), Hot Standby Router Protocol (HSRP), and Multigroup HSRP (MHSRP). These technologies provide network continuity in case of link or router failure, ensuring your critical operations remain online with zero-touch failover handling.

 
Powerful Performance Under Load – Cisco 921 Gigabit Ethernet Security Router – C921-4P

Unlike lower-tier edge routers, the C921-4P is designed to handle multiple simultaneous services—such as VPN, firewall, NAT, and QoS—without impacting throughput. This makes it suitable for environments with high traffic volumes, voice/video applications, or multi-service integration. Its internal processing ensures smooth performance even under demanding workloads.

 
Flexible Management and Configuration – Cisco 921 Gigabit Ethernet Security Router – C921-4P

Configuration is flexible with options for web interface, CLI, or Cisco Configuration Professional (CCP). A dedicated RJ-45 console port provides local access for initial setup or troubleshooting, and SNMP support enables remote monitoring. These features simplify management for both on-site and distributed IT teams.

 
Compact and Deployable Design – Cisco 921 Gigabit Ethernet Security Router – C921-4P

The router's compact form factor makes it ideal for tight deployment spaces such as retail counters, kiosks, and branch offices. It supports desktop or rack/wall mounting for flexible placement, and its dual power options (internal supply + external 12V DC adapter) provide added deployment flexibility and redundancy.

 
Expansion Ready – Cisco 921 Gigabit Ethernet Security Router – C921-4P

The USB 2.0 interface allows for connectivity with 3G/4G modems, enabling cellular failover support or file configuration. This enhances the router’s resilience and makes it suitable for mission-critical applications that demand constant uptime, even in locations with limited infrastructure.

 
Why Choose the Cisco 921 Gigabit Ethernet Security Router – C921-4P
