Helsinki Jon Geater CTO Trustonic OVER 100 EMPLOYEES technology LOCATED can already BETWEEN be found in over 300 Million smart devices and our growing ecosystem of service providers Cambridge, London, Tokyo stands at over Maidenhead, 50 companies Bath spanning enterprise, content protection, commerce and identity management segments. So, thank you to our partners for helping to establish this common Seoul Sophia, foundation Paris of trust in devices Now 2015 promises to be a year full of opportunity for those looking to deliver Taipei trust enhanced experiences to the masses! 4
