The Jericho Forum was an international group working to define and promote de-perimeterisation. It was initiated by David Lacey from the Royal Mail, and grew out of a loose affiliation of interested corporate CISOs (Chief Information Security Officers), discussing the topic from the summer of 2003, after an initial meeting hosted by Cisco, but was officially founded in January 2004. It declared success, and merged with The Open Group industry consortium's Security Forum in 2014.[1]
