Ultra High Performance

Ultra-high Performance powered by our next-generation multi-core hardware and Fastpath technology to create ultra-high efficiency. The USG FLEX H series can boost performance by up to 3x, optimizing utilization of its processors and allowing Zyxel to deliver superior performance to satisfy the needs required by demanding and high-speed networks.

Port Flexibility, Multi-G and PoE+

With 2.5 Gbps and 10 Gbps Port Speed options, The USG FLEX H also features software-defined ports, allowing you true flexibility in the configuration and tailoring of each USG FLEX H as required (WAN or LAN).

The USG FLEX H offers up to 2 x 30W PoE+ integrated ports^*1 to help reduce complexity by simplifying installations and reduce install costs by allowing you to power devices like 5G Routers, latest WiFi, or appliances like VoIP Phones directly from the USG FLEX H itself.

Hassle free network management with Nebula.

Utilizing nebula, Zyxel’s centralised cloud management platform you can configure and deploy network and security devices centrally.

You can manage multiple devices and bring the information from them together, combining it to create a more effective defensive ring around the network.

AI-powered cloud cybersecurity.

Network security constantly evolves to meet the demands of an ever-changing working environment. Block malicious threats and restrict inappropriate user behaviours. The USG FLEX H series leverages AI-powered cloud intelligence to operate multi-layered protection such as sandboxing, anti-malware, DNS/IP/URL filtering, IPS, and application patrol over your premises.

Our new Fast and Powerful uOS.

The USG FLEX H series introduces our latest powerful uOS (Operating System). It is designed to increase security, minimize system response time, apply configuration changes instantly and optimize configuration and security policy management with its new intuitive UX (User Experience) design.

Note:

*: This matrix with firmware uOS1.10 or later.

*1: Actual performance may vary depending on system configuration,network conditions, and activated applications.

*2: Maximum throughput based on RFC 2544 (1,518-byte UDP packets).

*3: VPN throughput measurement are based on RFC 2544 (1,424-byte UDP packets); IMIX: UDP throughput based on a combination of 64 byte, 512 byte, and 1424 byte packet sizes.

*4: Anti-Malware (with Express Mode) and IPS throughput is measured using the industry standard HTTP performance test (1,460-byte HTTP packets). Testing done with multiple flows.

*5: Maximum sessions are measured using the industry standard IXIA IxLoad testing tool.

*6: Including Gateway-to-Gateway and Client-to-Gateway.

*7: This is the recommend maximum number of concurrent logged-in devices.

*8: With Zyxel service license to enable or extend the feature capacity.
