Pontus Johnson

Pontus Johnson is a professor at the KTH Royal Institute of Technology in Stockholm, Sweden. His research interests mainly lie in the area of cyber security and the analysis of architectural models of computer networks – in particular simulating cyber attacks on such networks. Pontus supervises a number of PhD students and holds courses in Ethical hacking.

He is the director of the Center for Cyber Defense and Information Security at KTH, a collaboration with the Swedish Armed Forces, the National Defence Radio Establishment (FRA), the Swedish Civil Contingencies Agency (MSB), The Swedish Defence Research Agency (FOI) and the Swedish Defense University (FHS).

He is also the vice director of the national initiative Cybercampus Sweden, inaugurated February of 2024.

He received his MSc from the Lund Institute of Technology in 1997 and his PhD and Docent titles from the Royal Institute of Technology in 2002 and 2007. He was appointed professor in 2009.

Since 2013, Pontus is a member of the Swedish Royal Academy of Engineering Sciences (IVA). From 2024, he is serving on the IVA board as deputy chair. He has previously participated in various IVA projects – most notably the project on Cybersecurity and Competitiveness – chaired IVA's Division II, been a member of the medal committee, among other things.

He was a co-founder of Foreseeti, a research spin-off company developing cyber security attack simulation software, subsequently acquired by Google. Since 2023, Google offers Attack Path Simulations to its Cloud customers based on the technology developed by Pontus and his research colleagues.

In 2021, Pontus was credited with the discovery of the worlds oldest security vulnerability, in the universal Turing machine. In 2022 as well as 2023, Tech Awards Sweden listed him among the 50 most influential people in Swedish tech.

He has chaired, co-chaired, and participated as steering committee member in many international conferences and workshops and participated in program committees in over fifty such events. He has authored well over 100 scientific articles, mainly on the assessment and prediction of cyber security and other non-functional properties in software and computer networks.

Pontus spends 20% of his work time at Google. In the remaining 80%, he is a member of the Software Systems Architecture and Security (SSAS) research group within the Division of Network and Systems Engineering (NSE) at the Department of Computer Science in the School of Electrical Engineering and Computer Science (EECS) at KTH.
