The latest USG FLEX H firewall series is powered by the new uOS, which is designed to minimize system response time
and improve overall system efficiency, including the following features:

  • Introducing the Entry Defense Pack
    The USG FLEX H series now offers core protection features in a streamlined package, including real-time reputation filtering for robust threat defense. With SecuReporter for easy threat monitoring and Priority Support for fast assistance, it delivers reliable, simplified security for businesses.
  • Support FQDN Object
    Allows administrators to define domain names as security policy objects. This allows for dynamic filtering and access control based on domain names rather than static IP addresses.
  • Source IP Spoofing Prevention
    This feature ensures network security by verifying that devices use the correct IP address corresponding to their assigned MAC address. This helps block unauthorized devices from faking IP addresses to gain network access.
  • Centralized Network Management with Nebula
    We’ve enhanced Nebula with features that deliver enhanced control, visibility, and security:
    • Security Profile Sync. (SPS)- Provides robust multi-layer protection, including IP/URL/DNS Reputation Filtering, App Patrol, Web Filtering, Anti-Malware, and IPS.
    • Device Status- Real-time device status monitoring to track CPU and memory usage, session counts, and more.
    • Event Log Reporting- Simplifies troubleshooting with immediate insights into network activities.
  • Web Console
    Allowing administrators to easily manage and configure devices through a user-friendly web interface. It
    provides quick access to system settings and real-time monitoring from any browser.


  • Upgrade your devices to uOS1.30 for enhanced protection against the CVE references listed, as uOS1.30 is no longer vulnerable to them.
