History

Founded in Brisbane, Australia in 1999 by Oscar Marquez, iSheriff products focused on content filtering, email and Web filtering software and appliances. In 2009 the company moved its products to a cloud computing service model. iSheriff services include e-mail filtering, web filtering, email archiving, e-mail encryption and security reporting. The company holds a patent for its data modeling engine based on Bayesian spam filtering principals.

In 2006, iSheriff provided Internet filtering software to the Tasmanian government's first statewide trial of anti-pornography filters for children.

In July 2012, Total Defense, Inc., a provider of cybercrime-fighting technology, announced they had acquired iSheriff. On April 21, 2014, Total Defense announced that, in conjunction with the sale of their consumer business unit to Untangle, they re-branded as iSheriff.

In November 2016, Mimecast announced that it had purchased substantially all of the assets of iSheriff. Mimecast was later acquired by private equity firm Permira for $5.8 billion.
