The HiSecEngine USG12000 series is the industry's first terabit-level Artificial Intelligence (AI) firewall launched by Huawei for mitigating known and unknown threats at the network edge in real-time. It is typically deployed at the egress of cloud computing data centers, large enterprises, and campus networks to provide industry-leading protection capabilities. An advanced hardware architecture design and an array of energy conservation technologies slash energy consumption, while a full lineup of Line Interface Processing Units (LPUs) — with a per-slot interface density of up to 18 x 100 GE — meets heavy-bandwidth traffic requirements. The series provides comprehensive, carrier-grade high-reliability architecture, supporting a multitude of reliability mechanisms, such as dual Main Processing Unit (MPU) backup, Hot Standby (HSB), Non-Stop Routing (NSR), and Graceful Restart (GR). A hardware-based software integrity check mechanism prevents unauthorized software from running, ultimately building a secure foundation for the network. With terabit-level service processing power and a suite of security features — covering Network Address Translation (NAT), Carrier-Grade NAT (CGN), Virtual Private Network (VPN), virtualization, and content security — HiSecEngine USG12000 equips enterprises to handle the heavy bandwidth traffic and diverse service threats of the intelligent era.
