Zyxel USG FLEX 100H laitteistopalomuuri 3 Gbit/s

The Zyxel USG FLEX 100H is a high-performance hardware firewall designed to deliver secure, fast protection for VPN and Unified Threat Management (UTM). Built on next-generation multi-core hardware and Zyxel’s AI Security Cloud architecture, it provides multi-layered defenses for the firewall, network infrastructure and connected users while offering throughput suitable for demanding and high-speed networks.

Advantages

Ultra-high performance is achieved through multi-core processors and Fastpath technology, enabling up to 3x performance improvement and efficient processor utilization. The device offers flexible port options including 2.5 Gbps and 10 Gbps speeds and software-defined ports that can be assigned as WAN or LAN. Integrated PoE+ support (up to 2 × 30 W) simplifies installations by powering compatible devices directly from the firewall. Centralised cloud management via Nebula and AI-powered cloud security services provide automated threat intelligence and coordinated policy management. The new uOS operating system reduces system response time and simplifies configuration with an updated user experience.

Suitable for

• Small and medium-sized offices requiring high-throughput firewall and VPN
• Networks needing hardware-based IPS/IDS and malware protection
• Environments that benefit from centralised cloud management (Nebula)
• Installations that require PoE+ to power routers, Wi‑Fi access points or VoIP phones

How to use

Install the Zyxel USG FLEX 100H in your network rack or on a stable surface and connect the WAN and LAN using the Ethernet ports. Configure initial settings either locally via the web-based interface or remotely through Zyxel Nebula cloud management. Activate security services (sandboxing, anti-malware, DNS/IP/URL filtering, IPS, application control) according to your organisation’s policy and provision VPN tunnels (IKEv2/IPSec/SSL) for secure remote access. Use the uOS interface to apply configuration changes, monitor traffic and adjust security policies in real time.

Recommendations

For optimal performance, place the device in a well-ventilated location, keep firmware and threat signatures updated, and configure Nebula for centralised monitoring and policy orchestration. Enable only required services to conserve resources and review IPS and filtering policies periodically to maintain a balance between protection and throughput.
