Nebula Together

We are introducing USG FLEX to join the Nebula Cloud Management family. Simply implementing a firewall does not guarantee security when untrusted devices, users and applications are widely available. The revolutionary Nebula solution provides detailed Zero-Trust Network Security policies for organizations with access authentication and a secured Wi-Fi network.

The ultimate threat intelligence alliance

USG FLEX integrates threat intelligence from leading cybersecurity companies and organizations for scalable file intelligence and real-time threat intelligence. By leveraging broader malware coverage across a multi-source database, this increases threat detection accuracy.

Multi-layer, high-security protection

USG FLEX has been designed with multi-layer protection against many types of threats from inside and outside. Many security services allow you to limit inappropriate use of applications or network access by users. Zyxel offers an industry-leading DNS content filter that eliminates dead spots in all TLS 1.3 encrypted traffic without the need to implement SSL inspection. *UTM Security Pack license required.

Joint network defense

Firewalls detect threats on any connected client and sync with Nebula's command center, then automatically respond to cyber threats and stop devices at the edge (wireless access point) of your network. It is an ideal solution for IT departments that meets the requirements of decentralized network infrastructure and provides automatic protection.*UTM Security Pack license required

The same security in networks

Zyxel's new Secure WiFi feature allows you to create a drop-in access point that can be configured to replicate your office's SSID and automatically create a secure tunnel for seamless access to your corporate network. This simplifies implementation by creating a plug-n-play option while maintaining a high level of control over the security of remote workplaces. *Secure Wi-Fi license required

Analytical report and improved statistics

The FLEX USG Series dashboard provides user-friendly traffic summaries and threat statistics visualizations. Use SecuReporter for further threat analysis with correlation functionality that helps you proactively track network health and prevent further threat events. Centralized visibility of network activities, enabling easy management of multiple clients. *UTM Security Pack license required
