For 15 years, Tony's job has been either trying to break technology or defend it from attack. This he has done everywhere from banks to mass transport systems. He also speaks the world over at technology and cybersecurity events about how anything from children's toys to cars, planes and ships can be hacked. He has spoken at PCI events in Europe and Asia, at the SC Congress in London, ISACA CSX Europe, SANS Awareness Conference, WIRED Smarter, ENISA IoT Security Conference, technical conferences such as 44Con and BSides. Most notably, he has spoken to US Congress and the European Central Bank about how the underlying digital theories and systems which modern life relies on, are vulnerable to attack.
