From Wikipedia, the free encyclopedia

CipherTrust was an anti-spam email software company based in Alpharetta, a suburb of Atlanta, Georgia, with offices around the world. It was cofounded by Jay Chaudhry and Lawrence Hughes (both formerly with SecureIT).[1] Since August 2006 it is part of the Secure Computing Corporation, which was acquired by McAfee in 2008.


CipherTrust's main product is the IronMail, a gateway appliance that prevents leaks from uploading HTTP or FTP transfers through e-mail applications.[2] It added a product to secure Instant Messaging called IronIM. The CTO, Paul Judge, chaired the Anti-Spam Research Group of the Internet Research Task Force. The firm also tracks zombie computers, a primary source of spam.[3]

CipherTrust invented the TrustedSource reputation system that provides reputation scores for Internet identities, such as IP addresses, URLs, domains and email/web content. This became part of all its products and a main reason for its eventual buyout.


In August 2006, the Secure Computing Corporation bought CipherTrust shares for US$273.6 million. The new company still offered previously exclusive technologies.[1]
