Welcome to COSAC - Conferencing the way it should be! For 25 years COSAC has delivered a trusted environment in which to deliver information security value from shared experience and intensive, productive, participative debate and development. Sales content is strictly prohibited and there is no vendor exhibition to distract from opportunities, allowing delegates to focus on professional innovation. The Call for Papers for our 25th annual event in Ireland is now closed. The agenda for the 25th COSAC Security Conference will be published in mid-April.
