About the Huawei HiSecEngine USG6635F Next-Generation Firewall
The Huawei HiSecEngine USG6635F is a 2U rackmount next-generation firewall delivering exceptional port density with 2 × 40GE QSFP+ interfaces, 8 × 10GE SFP+ ports, and 8 × GE RJ45 connections, plus 4 expansion slots for future interface growth. This enterprise-grade appliance is purpose-built for network engineers and IT procurement teams requiring high-performance threat protection across large-scale branch and data center deployments.
The USG6635F combines multiple security functions into a unified platform: firewall, IPS, antivirus, URL filtering, anti-APT, SSL decryption, application control, and DDoS protection. Huawei engineered this device to sustain 40 Gbps firewall throughput while delivering 18 Gbps IPS performance, 10 Gbps threat protection, and 8 Gbps SSL inspection throughput. It manages up to 20,000,000 concurrent sessions and processes 600,000 new sessions per second, making it suitable for carrier-grade and hyperscale environments. The platform supports IPsec VPN, SSL VPN, L2TP, and GRE protocols across both active-active and active-standby high availability modes. Dual redundant hot-swappable power supplies ensure continuous operation, while virtual firewall (VSYS) support enables logical segmentation across multiple tenants. With routing capability including static, RIP, OSPF, BGP, IS-IS, and policy-based routing, Huawei delivers comprehensive network integration alongside security enforcement. Operating from 0°C to 45°C with maximum power consumption of approximately 350 W, the USG6635F fits standard enterprise data center infrastructure footprints.
