The new firewalls are compatible with Zyxel Networks' full suite of Unified Threat Management security services (including web filtering, application patrolling, and antimalware). These services are further enhanced by advanced features such as sandboxing, IP reputation filtering, and DNS filtering for customers requiring an extremely fast and reactive approach to network security.
Technology at the service of SMEs for a new protection framework.
Both Artificial Intelligence and sandboxing provide greater network isolation to respond to potential and even unidentified threats, containing them by leveraging the latest cloud technologies, such as Zyxel's Nebula. Furthermore, Zyxel's filtering technologies prevent up to 70% of threats at the first line of defense, including DNS content filtering and reputation filtering, eliminating blind spots even with encrypted traffic. No IT expertise is required to operate Nebula, which guides users through each step of the process.
The Zyxel USGFLEX Ultimate H series features content filtering capabilities, including IP checking with cloud-synchronized categories that are continuously updated via an ever-evolving cloud. Meanwhile, Collaborative Detection & Response (CDR) allows network devices to work together to block or quarantine compromised devices/clients at the network edge. And anti-malware and ransomware protection reinforces against the latest threats, all in a centralized manner.

“Zyxel’s latest network protection technology is the result of our company’s continuous research and development in security, based on the real-world, daily needs of small and medium-sized businesses,” says Gonzalo Echeverría, Country Manager of Zyxel Iberia. “The Zyxel USGFLEX Ultimate H series represents a significant leap forward in network security because it leverages cloud capabilities and AI features to deliver the latest network protection technology to these increasingly vulnerable businesses, always at an affordable price.”.
Easy NIS2 Compliance for SMEs.
Furthermore, in compliance with the NIS2 standard, Zyxel applies the necessary requirements to all its security solutions to strengthen protection according to the regulation. This ensures compliance and protects the integrity of users and businesses. The firewalls use advanced threat detection and prevention technologies to defend against sophisticated cyber threats such as ransomware, malware, zero-day exploits, and advanced persistent threats (APTs). They also incorporate an Intrusion Detection and Prevention System (IDPS) that monitors network traffic for malicious activity.
Thanks to Zyxel Networks solutions, SMEs can easily comply with NIS2, a more demanding cybersecurity standard than its predecessor, thus strengthening their security. The company also provides support from a team of specialists and qualified partners to guarantee continuous protection and compliance with the regulation, as well as the security and resilience of networks and information systems.
During the presentation of the latest features of the Zyxel USGFLEX H firewalls, Gonzalo Echeverría highlighted the rapid adoption of Wi-Fi 7 technology due to its tri-band and multilink capabilities, particularly in the hospitality sector. The company anticipates that 35% of sales in 2025 will be for Wi-Fi 7-enabled equipment and forecasts a 15% increase in total sales.
