Field Communications Security: How Virtual Routing and Forwarding (VRF) Enhances Network Integrity for Utilities

Field operations in utilities are increasingly reliant on cellular connected assets – ranging from SCADA systems and telemetry sensors to rugged laptops, IP cameras, and real-time monitoring tools. With this growing complexity comes a critical need for secure, segmented networking across Field Area Networks based on LTE 4G and 5G connectivity. 

Join Aviat Networks for a focused webinar on how Virtual Routing and Forwarding (VRF) router technology strengthens cellular based Field Area Network security in industrial deployments: 

• Isolates and secures traffic: Create virtual routers for each application—ensuring that sensitive operational data (e.g., ICS SCADA traffic or safety system telemetry) remains isolated from less critical services like remote video feeds or general field force internet access. 
• Reduces the attack surface: Contain potential threats within individual VRF instances to prevent lateral movement and minimize the impact of breaches. 
• Enables independent policy control: Apply tailored security policies (ACLs, QoS, etc.) to business-critical networks while maintaining flexibility or even Internet access for auxiliary systems. 
• Supports multi-tenancy: Manage overlapping IP address spaces across different sites or divisions (gas and electric) without relying on NAT, VLANs, or complex addressing. 
• Prevents route leakage and misconfiguration: Ensure clean separation between operational ICS/SCADA zones and corporate IT/productivity networks, reducing risk and simplifying troubleshooting. 

By delivering Layer 3 segmentation similar to VLANs at Layer 2, VRF is a powerful tool for building resilient, secure, and scalable FAN networks. Whether you are managing connectivity for substations or field force support, this session will offer actionable insights into how VRF supports operational integrity and cybersecurity.  

Who Should Attend: 

• IT and network professionals in electric, water, natural gas, and other public utilities 
• Field operations and infrastructure managers 
• System integrators and industrial solution architects 
• Anyone involved in LTE 4G and 5G router deployment or industrial network security
