Untangle was founded in 2003 as Metavize, Inc. by John Irwin and Dirk Morris. In 2006, Metavize raised a $10.5M series-A venture funding round from CMEA Ventures and Rustic Canyon Partners, named Bob Walters as CEO, and renamed to Untangle, Inc.[2] In 2007, Untangle released the Untangle Gateway Platform as open source under the GPLv2 license.[3]

In October 2009, Untangle released Untangle 7.0 which included improvements to its reporting capabilities.[4] In December 2009, Untangle released Untangle 7.1 which included improvements to its web filtering and policy management applications.[5] In March 2010, Untangle released Untangle 7.2 which included its Captive Portal application.[6]

Untangle released a free bookmark utility called SaveFace in May 2010, in response to continued loosening of default privacy settings in Facebook user accounts.[7][8] In June 2010 Untangle released Untangle 7.3, enabling the company's software to be used by OEM hardware manufacturers to produce their own branded multi-function firewalls and UTM appliances.[9] In August 2010 Untangle released Untangle 7.4, wherein it simplified its packages to Lite, Standard, and Premium.[10]

In November 2010 Untangle released Untangle 8.0, which included Bandwidth Control.[11] In February 2011 Untangle released Untangle 8.1, which included Web Cache.[12] Untangle 9.0 was released later in 2011, and included IPsec VPN support.

In February 2012 Untangle released Untangle 9.2, which included Application Control.[13] Application Control allows users to block, flag, or tarpit applications and protocols. For a greater degree of control, administrators can create custom rules in the proprietary Integrated Rules Engine (IRE), which target more complex traffic patterns.

In March, 2012, Untangle released a new appliance line, answering the request of customers for an easier way to deploy Untangle on certified hardware.[14]

In April, 2012, Untangle changed the content of the Standard Package to include both IPsec VPN and Application Control.[15]

In August, 2012, Untangle released Untangle 9.3, including full tunnel OpenVPN.

In January, 2013, Untangle released Untangle 9.4, including an all-new Captive Portal to work with its Integrated Rules Engine (IRE), allowing for varied use cases like mobile device management for bring your own device (BYOD) environments, integration with payment providers to support paid access for wi-fi hotspots, and separate policies for wi-fi and wired users. Other changes included an improved Session Viewer and new Host Table view.

In September, 2013, Untangle released Untangle 10.0, including HTTPS Inspector, a new app that allows Untangle to inspect traffic over HTTPS. This allows HTTPS traffic to be scanned by the full suite of Untangle applications and allow rules to be applied to it. Other improvements include IPv6 configurability, 802.1q tagged alias (VLAN tagging) support, a simpler and more powerful NAT implementation and better PPPoE support.

On October 1, 2013, Untangle acquired Cymphonix Corporation, an Internet management network appliance company.
