Dear Customer,

We recently became aware of a sophisticated threat actor targeting a small subset of Zyxel security appliances that have remote management or SSL VPN enabled. This mitigation firmware will actively guide users to follow general security best practices to reduce the attack surface. The new features include: 

  •  Initial Setup Wizard Enhancements

Helps users to enforce security policies against access to the web management interface and SSL VPN service from the Internet.


  • Security Policy Check

Shows misconfiguration of security policies through a pop-up notification, along with firmware update and change password reminder.


  • Configurable SSL VPN and WAN Access  

Separates access options on SSL VPN and WAN Access service.


  • Log Enhancement

Provides a log history when the user object has been changed.


  • GeoIP Now a Complimentary Feature

Built-in GeoIP feature to strengthen security access-which is now available free of charge for the entire firewall range.
