Nebula Together
We bring USG FLEX to join the Nebula Cloud Management family. Simply deploying a firewall will not guarantee safety while untrusted devices, users, and applications are accessed widely. Nebula's revolutionary solution brings a Zero-Trust Network Security granular policy to organizations with access authentications and secured WiFi.

Best threat intelligence alliance
USG FLEX integrates threat intelligence from leading companies and organizations in the cybersecurity field for scaled information about file and real-time threat data. By leveraging a wider malware coverage with multiple-sourced database, this increases the accuracy in threat detection.

High assurance multi-layered protection
USG FLEX is designed with multi-layer protection against multiple types of threats from in and out. Multiple security services empower you to restrict users' inappropriate application usage or web access. Zyxel offers leading-industry DNS content filter, eliminating blind spots in all encrypted traffic with TLS 1.3 without the need to deploy SSL inspection. *UTM Security Pack license required

Collaborative Network Defense
The firewalls detect a threat on any of the connected clients and will sync with the Nebula control center, then automatically respond to cyber threats and contain the device(s) at the edge (Wireless Access Point) of your network. It is a perfect fit for IT to address the requirements of a decentralized network infrastructure and provide automatic protection.*UTM Security Pack license required

Same Security Across Networks
Zyxel's new Secure WiFi feature gives you the ability to create a “drop-in” Access Point that can be configured to replicate the SSID of your office and automatically create a secure tunnel, creating seamless accessibility to your corporate network. This simplifies the deployment by creating a plug-n-play option while maintaining a high level of control over the security of remote workplaces. *Secure WiFi license required
