Engineered for Line-Rate Carrier Scale
When a mobile subscriber connects to a home or public Wi-Fi hotspot, ePDG secures their connection to the mobile operator core via an authenticated IPsec tunnel (IKEv2 with EAP-SIM/AKA). This allows high-definition VoWiFi phone calls and SMS without cellular coverage.
Hardware-Accelerated Cryptographic Crypto Tunnels
Operates on standard COTS servers (Intel Xeon / AMD EPYC), bypassing Linux kernel latency via DPDK user-space drivers.
Key Architectural Capabilities
Everything required to inspect, control, monetize, and protect multi-gigabit carrier traffic.
