Untangle NG Firewall

Your network. Your rules.

Simple, Powerful, All-In-One Network Security

The right network security solution provides protection and policy enforcement while maximizing user productivity and satisfaction. Your network faces external threats such as attacks, viruses, phishing and spam. It also faces internal threats from bandwidth- and productivity- draining apps, inappropriate websites, and more. To complicate matters, certain network policies might apply to one group (e.g. marketing team) and not another (e.g. finance team).

The legacy approach to firewalls—blocking suspect ports—simply doesn’t work with today’s applications because both beneficial and malicious apps use port-hopping strategies to deliver high Quality of Service (QoS). Throw in remote and mobile users connecting over insecure and public access points, and you have security challenges that require a Next Generation Firewall like Untangle’s.

Untangle’s NG Firewall enables you to quickly and easily create the network policies that deliver the perfect balance between security and productivity. Untangle combines Unified Threat Management (UTM)—to address all of the key network threats—with policy management tools that enable you to define access and control by individuals, groups or company-wide. And with industry-leading reports, you’ll have complete visibility into and control over everything that’s happening on your network.

Security that Fits You

The NG Firewall platform is designed to work like an app store. Apps are plug-ins that add functionality to the NG Firewall platform, just like apps on a smartphone. Though each app has a different task, like blocking spam or preventing virus infections, all of the apps work together in concert via NG Firewall’s powerful, flexible Integrated Rules EngineTM. This allows you to create granular policies to handle every type of traffic, threat or optimization need regardless of the complexity of your network or organization. Even better, NG Firewall includes on-board reports that let you not only drill down app-by-app, but across all applications by user, group, time of day and much more. Every dataset available in NG Firewall is available to you via Reports.

New in Version 12

Untangle NG Firewall v12 brings new features and functionality to the platform.

360° Dashboard

The dashboard is a new way to look at the data available in the Reports app, as well as acting as a single pane of glass providing security alerts and insight into system performance. Some of the pre-configured widgets available in the dashboard include:

  • System and hardware information
  • Network interfaces
  • CPU load, memory resources, server resources
  • Hosts & devices
  • Sessions
  • Alert events
  • Web Filter usage
  • Bandwidth Control top hostnames

Administrators can add to or replace these widgets with custom widgets they can create using any of the data available in Reports.

Version 12 also brings a fresh look to the administrative interface which is now simpler, cleaner, faster and more responsive on mobile devices. This enables busy IT administrators to keep tabs on their network anytime, anywhere directly from their smartphones. There are now four global tabs available in the administrative interface: Dashboard, Apps, Config, and Reports. These tabs provide quick, easy access to all reporting and management features.



With version 12, Untangle has further extended the capabilities of the NG Firewall platform to integrate with the Untangle cloud service, ScoutIQ, an intelligence infrastructure that powers the onsite instances of NG Firewall with global insights from threat intelligence metadata. Virus Blocker is the first app to utilize ScoutIQ, performing a cloud scan concurrently with a local scan, resulting in greater protection against zero day and emerging threats. Additionally, version 12 uses ScoutIQ to improve email deliverability, ensuring that administrative alerts aren’t missed.


Other Major Features

  • Device awareness for Internet of Things security. Version 12 adds a Device List which tracks devices on the network by MAC address and gathers pertinent data about them, enabling administrators to create rules and alerts to manage them.
  • Faster Reports, now with Google Drive storage. Version 12 logs five times the number of events per second on the same hardware and features Google Drive integration for offsite data storage for daily logs as well as configuration backup.
  • Greater support for third party hardware. This allows you to choose between using your own servers or a turnkey Untangle appliance.
