The ZYXEL USG FLEX 500 Network Security/Firewall Appliance, part number USGFLEX500, delivers scalable protection and centralized management for small and mid-sized business networks. Designed for rack-mount installation, this ZyWALL USG FLEX appliance combines firewall security, VPN connectivity, wireless protection, and cloud management flexibility in a unified platform. Its optimized architecture helps reduce computing power usage while providing high-performance security processing for demanding business environments.

Nebula cloud management and unified security

With support for the Zyxel Nebula cloud management platform, the USG FLEX 500 enables centralized provisioning, policy management, traffic shaping, and remote administration. IT teams can manage security policies across distributed locations and remote users while maintaining consistent protection. The appliance can also adapt to on-premises management for organizations that require local control, providing a flexible transition between deployment models without changing the overall security strategy.

Multi-layered protection for modern threats

The USG FLEX 500 helps secure network traffic with anti-malware, intrusion prevention, DNS and URL filtering, application patrol, and automated threat containment at the network edge. AI-supported security services and multi-source threat intelligence improve detection accuracy across file-based and real-time threats. TLS 1.3-aware DNS content filtering helps reduce visibility gaps in encrypted traffic without requiring SSL inspection, while web filtering supports safer internet access for employees and guests.

Secure connectivity for users and devices

Integrated Wi-Fi 6 technology supports dual-radio wireless performance of up to 1,800 Mbps, helping accommodate modern devices and remote-work requirements. Two-factor authentication adds another layer of account protection, while Device Insight improves visibility into connected equipment and user activity. Compatible SecuExtender support can extend security controls to employees working outside the office. Optional Gold Security Pack services add capabilities such as sandboxing and reputation filtering for expanded threat defense.
