He has acted in various roles there, including CEO for about five years. After they sold SensePost to SecureData, he took a diverse role within the group that includes leading its research unit, directing security strategy and leading the "Security Intelligence Unit," which (amongst other things) runs a significant Managed SIEM and Threat Hunting (MDR) Operation.

George Beebe, Vice President and Director of Studies, Center for National Interest (USA)

George Beebe is one of America's most well-informed and insightful experts on international affairs and foreign policy. He has an especially strong background in cyber security, US intelligence, US-Russia relations, and the challenges of the changing international order. George Beebe is Vice President and Director of Studies at the Center for National Interest. He is former President of BehaviorMatrix LLC, a technology company that measured audience response to events, issues, and commercial brands. His new book (August 2019), The Russia Trap: How Our Shadow War with Russia Could Spiral into Nuclear Catastrophe, examines how changing technology, the dysfunctional politics, garbled communications, and unsettled regional conflicts are combining to trap the US and Russia in a disastrous escalation spiral neither one wants or expects. George has spent more than two decades in government service as an intelligence analyst, diplomat, and policy advisor. A speaker of both Russian and German, he was the director of the CIA's Russia analysis and Special Advisor to Vice President Cheney for Russia/Eurasia and Intelligence Programs. He also is well versed in the challenges the US faces in North Korea and the Middle East. George speaks with unparalleled authority on cyber security and information warfare. He brings to his presentations a unique combination of expertise in technology, experience with intelligence practice, and connections with the intelligence community.

Digital Enterprise Show 2019:
Review from a recent cybersecurity event that George spoke at:
George Beebe delivered a tremendous opening keynote session at our [ ... ] event that our attendees were talking about all day. He was an absolute pleasure to deal with both onsite and in the run-up to the show and I’d have no concerns recommending him to anyone looking for a knowledgeable speaker on cybersecurity and more specifically Russia’s role in what is happening in cyberspace.

Dr Suelette Dreyfus, Academic Specialist, School of Computing and Information Systems, University of Melbourne (Australia)

Dr Suelette Dreyfus is a Lecturer in the School of Computing and Information Systems at The University of Melbourne. She did her bachelor’s degree at Columbia University (Barnard College) in New York and her Ph.D. at Monash University. She is a frequent public commentator in the media on IT-related topics. Her main research areas are: cyber security and hacking, digital privacy and anonymity, the impact of technology on integrity systems (whistleblowing) and social media as a tool for language learning in schools. She wrote Underground, the first mainstream book about computer hacking in Australia, with Julian Assange, which was subsequently made into two different films and translated into seven other languages. Rolling Stone Magazine described the work as ‘entirely original’, and the book has become a cult classic.

For her research work on the impact of digital technologies on whistleblowing, she has been invited to appear before several parliamentary committees at a state and federal level in Australia. She has co-authored several international reports and papers in this area. She works with civil society not-for-profit NGOs internationally which seek to improve the whistleblower protection structures in their society, both in law and via use of technology. She has integrated these two research areas by co-developing an experimental programme to teach journalists how to protect their whistleblower sources by improving data security and anonymity.

Her e-education research work is in the use of social media for education. She initiated an innovative cross disciplinary project using social media to teach Chinese to Australian primary school children in Australia, and English to Chinese students in China. Prior to earning her PhD and entering academia, she trained and worked as a staff journalist on a major daily newspaper in Australia. Suelette is particularly enthusiastic about encouraging and supporting women in IT.

Uri Rivner, Chief Cyber Officer & Co-Founder, BioCatch (Israel)

Uri Rivner has been fighting online fraud for twenty years, working closely with major financial institutions on developing strategies against cybercrime. Uri started his security career at Cyota, the anti-fraud company that was later acquired by RSA. He joined in 2000 and spent years working closely with the best fraud teams worldwide, gaining deep perspectives on cybercrime, thinking of innovative solutions and building them. Uri took a central role in developing technologies now used by thousands of financial institutions, protecting roughly one billion online banking users, and stopping billions of dollars in fraud each year.
As Head of New Technologies, Identity Protection at RSA, Uri helped corporations shape a new defence doctrine against emerging cyber threats. During his 12th year at RSA he came across an intriguing new start-up called BioCatch, an invisible biometrics company for mobile and web. It has a very cool "twist" to behavioural biometrics. Uri is currently working with the world’s leading banks and corporations on mitigating advanced cyber threats and is enjoying the thrill of an early stage start-up that can finally bring practical biometrics to the world of mobile, cloud and web.
