Excellent SMB Firewall

Score 9 out of 10
Vetted Review
  • Secure firewall
  • Easy to use VPN (with OpenVPN)
  • Active directory connector with 2fa for VPN is very easy to implement
  • Fairly intuitive internet filter
  • Great support
  • Only issue is that the device limits are anemic. Far too low for most SMBs in an iot era.

  • Multiple security apps (Web Filter, Virus Scanner, Bandwidth Control, Application Control, SSL Inspection, IDS/IPS, Threat Prevention, etc) all work together to provide a multi-layer security approach.
  • The logs and reporting are detailed and extensive. That can sometimes be overwhelming, but also invaluable once you know how to use them.
  • Untangle is much, much more than "just" a web filter. The academic discount is completely worth what is provided.
  • Of course, Untangle support is very good. Their community forums are also very strong.
  • These areas of improvement have already been submitted to Untangle for review. One of them is the ability to filter by user groups the login access used by the Captive Portal app.
  • This is always under improvement, but working on the reports to help them to not be as overwhelming to new users. Also the ability to have a dedicated reporting "dashboard" for specific users, especially if parents request that information. It can be done, but it isn't that easy to set up.
  • Finally, due to recent academic developments, the ability to expand an existing Untangle appliance to the cloud for cloud-based filtering would be amazing for schools. That is easy to say, but obviously more difficult to achieve.

  • Easy to understand with its graphical interface.
  • Runs on Linux so it's durable and safe.
  • Supports major VPN's and is compatible with Cisco.
  • Protecting kids while on internet with modules it has that some cost.
  • Can run on many types of hardware from servers to some home firewall units.
  • The full suite can be expensive for business but will be powerful enough.
  • The full suite for home or small office isn't that bad of a price but may be out of reach for most home users but remember the basics are FREE so anyone can get started with it.
  • I would like to see it promoted for mid to large businesses as I think it can handle it.

  • The firewall is easy to set up and manage.
  • The open VPN while not as feature rich as some other options is rock solid and consistently needs nothing
  • The web filter app is great, it's easy to block broad categories or specific things as well as white list whatever is needed.
  • Support is responsive and accurate.
  • The dashboard could be a little more customizable.
  • I've run into situations where custom reports do not save correctly.
  • It's not always clear where certain configurations are located, but it's still easy to find them quickly.

  • Web Filtering is strong, and can also do application fingerprinting to allow Facebook, but not Facebook games. Secondly, a separate partition called a "rack" can be set up to give one subnet or group of users different web filtering policies than another. For example, teachers would get more freedom to browse the web than students at a school.
  • Built-in SD-WAN connectivity as part of your license. IPSEC tunnel creation is also amazingly easy.
  • Will install on any x86 hardware created in the last 5-10 years. Ram and processor requirements per user are very low.
  • Reporting is phenomenal, however you can get death by details very easily.
  • The UI could be a little flashier.
  • Getting your license file moved from one firewall to another can be tough at times... but support is great if you need it.
  • Ability to upload reports to a portal versus getting them emailed would be best (some reports can get 100+ Mb depending on all the bells and whistles).

  • Web filtration works well and is very easy to manage. The interface is intuitive and makes dealing with end user issues quick and easy to resolve.
  • Bandwidth control is a nice feature that quickly lets you determine where the offending bandwidth consumer is.
  • The reporting feature is rich and the emailed reports help you determine any potential problems that may need to be addressed.
  • Probably the documentation, the online tutorials could be a little more up to date and clearer.
