Firewall Zyxel USG Flex 100HP 3 Gbit/s throughput VPN IPSec SSL

Zyxel USG Flex 100HP is a hardware firewall that provides up to 3 Gbit/s firewall/UTM/VPN throughput and multi-gigabit PoE+ ready interfaces for growing network demands. The device supports IKEv2, IPSec and SSL VPN, with IPS/IDS throughput up to 1.5 Gbit/s. Powered by Zyxel AI cloud and Nebula cloud management compatibility, it delivers multi-layered security including DNS content filtering and collaborative threat intelligence while offering centralized monitoring and traffic analytics. The unit is compact and energy-efficient, operates from a 19 V DC input and consumes up to 51.2 W.

Advantages

USG Flex 100HP combines high throughput and enterprise-grade security features in a single appliance, supporting fast VPN connections and strong intrusion prevention. Integration with Nebula enables centralized cloud management, zero-trust access control and automated responses to detected threats. The firewall leverages multi-source threat intelligence and DNS content filtering to increase detection accuracy and mitigate risks across encrypted traffic without mandatory SSL inspection when applicable. Designed for easy deployment, it also supports Secure WiFi tunnels and centralized reporting with SecuReporter (certain features require appropriate licenses).

Suitable for

• Small and medium-sized offices requiring high-performance firewall and VPN throughput
• Distributed or remote-office environments that need centralized cloud management (Nebula)
• Networks that require intrusion prevention (IPS/IDS) and DNS content filtering
• Organizations wanting collaborative threat response across endpoints and access points

How to use

Install the Zyxel USG Flex 100HP in the network rack or on a stable surface and connect the WAN and LAN interfaces using Ethernet cables. Power the device with a compatible 19 V DC adapter. Configure initial settings through the local console or web interface, or register the appliance in Nebula Cloud Management to enable centralized provisioning and policies. Enable required UTM services, VPN profiles (IKEv2/IPSec/SSL) and content filtering according to your security policy. Apply and test firewall rules and VPN connections before deploying to production traffic.

Recommendations

For best results, enable Nebula cloud management to use centralized monitoring and automatic threat response, and consider purchasing the UTM Security Pack and Secure WiFi licenses to unlock full DNS filtering, advanced threat protection and secure WiFi tunnel features. Regularly update signatures and firmware and review SecuReporter analytics to maintain accurate threat detection.
