ZyXEL USG FLEX 100H Firewall Appliance

The ZyXEL USG FLEX 100H is a wired network security appliance designed for enterprise environments. It delivers firewall throughput of 2.93 Gbit/s alongside VPN throughput of 93.75 MB/s and IPS throughput of 187.50 MB/s. The bundle includes a one-year Gold license package and one-year Nebula Cloud Pro subscription for cloud-based management.

Suited For And Not Suited For

This appliance suits organisations requiring multi-layered threat protection including cloud sandboxing, malware protection, intrusion prevention, application control, DNS security, URL filtering, and SSL inspection. It supports up to 25 concurrent VPN tunnels and 300000 concurrent sessions. Buyers needing wireless connectivity, higher port density, or throughput beyond the stated figures should consider alternative models.

Sustained Load Behaviour

Power consumption is rated at 17 W, reflecting the dedicated system resources engineered to minimise packet processing time and reduce latency during continuous traffic flows. The eight Gigabit Ethernet ports operate at 1000Base-T with encryption standards including AES 256-bit, 3DES, DES, SSL, MD5, SHA-1, and SHA-2 256-bit. A USB port and console cable are included for additional connectivity options.

Questions about this item

What WAN uplink speed can the eight Gigabit RJ-45 ports on this USG FLEX 100H actually utilise?

Each of the eight RJ-45 ports supports 1000Base-T, so the maximum WAN uplink speed is 1 Gbit/s per port.

Will my existing Cat 5e patch cables limit the 2.93 Gbit/s firewall throughput of this appliance?

Cat 5e cable is rated for 1 Gbit/s per link; the 2.93 Gbit/s aggregate throughput is reached by summing traffic across multiple ports, not by exceeding 1 Gbit/s on a single cable.

How can I verify the Gold bundle licenses are active after registering the device in Nebula?

In the Nebula dashboard, open License & Inventory; the Gold bundle shows "Active" with an expiry date one year from registration.
