FlexRouter
Reliable Internet Connectivity
Cost-effective branch Router/Firewall for scalable and reliable connectivity.
Advanced Routing Engine
Full IPv4/IPv6 support with dynamic routing (OSPF, BGP, RIP), VRFs, and VLANs
Integrated Firewall
Stateful L3/L4 filtering, ACLs, NAT, and traffic shaping for secure connectivity
High-Performance Connectivity
Up to 1 Gbps throughput with ECMP, link bonding, and hardware efficiency
Zero‑Touch Deployment
Remote provisioning and centralized configuration
Operational Efficiency
Fewer devices, simplified operations, and reduced support overhead
Service-Ready Flexibility
One routing platform reused across customers, sites, and services
Built for Reliable Layer-3 Edge Connectivity
FlexRouter is for organizations that rely on stable, always-on Internet connectivity to keep their business running. Delivering resilient L3 routing with dynamic path control, encrypted VPN tunnels, high availability, and traffic management, FlexRouter ensures consistent access to applications, cloud services, and internal networks across distributed sites.
The FlexConnect family is built around flexibility at the network edge.
By decoupling software from hardware, our Flex products enable cost-effective network services on the same device across multiple customers and sites, reducing inventory, simplifying operations, and lowering OpEx and CapEx.
FlexRouter brings flexibility to L3 connectivity, enabling a single routing and firewall platform to be reused across different customers, sites, and configurations. Easy to standardize and remotely manage, FlexRouter delivers reliable Internet connectivity and advanced routing at scale, without the complexity of SD-WAN or NGFW.
Network Fit
FlexRouter helps service providers stay competitive by lowering service delivery costs and improving operational efficiency, enabling standardized routing services, faster service changes through remote management, and reduced inventory as networks scale.
FlexRouter simplifies branch connectivity with centralized control, resilient routing, and integrated L3/L4 security, reducing IT overhead per site while ensuring reliable access to business-critical applications and services.
Core Deployment Scenarios
Secure Branch Connectivity
Deploy encrypted tunnels and HA routing to ensure uninterrupted access to critical internal services
Hybrid Connectivity
Leverage MPLS, broadband, and LTE/5G links with dynamic failover and intelligent traffic distribution
Network Segmentation
Use VRFs, VLANs, and policy-based routing to cleanly separate business units, customer environments, or service tiers
This architecture shows how branch offices maintain continuous internet access through multiple WAN paths, including MPLS and broadband, while securely extending the network over encrypted site-to-site tunnels. Traffic is routed locally at each site, with automatic path selection and failover ensuring availability even during link outages. The result is a stable, secure WAN foundation that supports diverse access technologies such as Wi-Fi, LTE/5G, and fiber without introducing additional edge complexity.
