The Zyxel Nebula gateways can be quick and easy deployed at a remote location through nearly zero-touch cloud provisioning. It automatically pulls policies and configuration settings, receives seamless firmware upgrades and security signature updates from the cloud without the need for on-site networking expertise. Nebula cloud interface provides site-wide visibility and control that enable administrators to manage event logs, traffic statistics, bandwidth consumption, networked clients and application usage without access to the individual devices. Establish VPN to keep branch locations securely connected is easier than ever. With the Zyxel Nebula Security Gateway, either site-to-site or hub-and-spoke VPN connections can be configured with complete simplicity through few clicks in the Nebula Control Center, without complex VPN configuration steps. The Zyxel Nebula gateways streamline configuration of firewall and every security feature for faster, easier and more consistent policy settings by supporting object-based management and a unified configuration approach for all security related policies, with which users can easily apply all policy criteria to every security feature. Moreover, any configuration made in the Nebula Control Center can automatically propagate to all the connected Nebula gateways. Nebula's Intrusion detection and prevention system scans multiple layers and protocols to inspect vulnerabilities invisible to simple port-and protocol-based firewalls by utilizing Deep Packet Inspection (DPI) technology that eliminates false positives with a database of malware signatures and provides effective protection against intrusions from unknown back doors.
