In the context of an international university cooperation, he then did his Bachelor\u2019s thesis on successfully accessing contactless readable smartcards using an NFC-enabled Android device.\nTo become an IT security expert, Michael Br\u00fcgge then started the master\u2019s program \u201cIT Security \/ Networks and Systems\u201d at the University of Bochum, switching to cirosec GmbH for his thesis. In this context, he analyzed and compared standards for penetration testing.\nAfter finishing his studies, he started working as a consultant at cirosec GmbH at the beginning of 2015.\n\n\n\n\nSince then, Michael Br\u00fcgge has gained experience in different areas, such as in carrying out demanding penetration tests and insider analyses as well as conceptual reviews of security architectures. He also consults customers on building a security operations center, is a trainer of the \u201cHacking Extreme Web Applications\u201d cirosec training and has the OSCP+ certification.\nAs a Managing Consultant, he has been having personnel responsibility for a team of ten since 2021. In addition, Michael Br\u00fcgge heads the cirosec red team and, together with his colleagues, carries out several red team assessments each year. In doing so, he is not only responsible for project management but also has specialized in carrying out social-engineering attacks and bypassing physical security controls. His knowledge of how to protect a company from such attacks is passed on by him to cirosec\u2019s customers in the form of security awareness campaigns, live hacking presentations and workshops.\nMichael Br\u00fcgge is also part of the incident response management team, regularly assisting customers in handling various IT security incidents and carrying out forensic analyses.\"\r\n\t\t\t data-img=\"https:\/\/it-defense.de\/it-defense-2027\/wp-content\/uploads\/sites\/8\/2026\/10\/Michael-Bruegge_Hoodie-1.png\"\r\n\t\t\t data-alt=\"Michael Br\u00fcgge\"\r\n\t\t\t role=\"button\"\r\n\t\t\t tabindex=\"0\"\r\n\t\t\t aria-label=\"Michael Br\u00fcgge\">\r\n\t\t\t<div class=\"rg-img-wrap\">\r\n\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" alt=\"Michael Br\u00fcgge\" loading=\"lazy\" class=\"lazyload\" data-src=\"https:\/\/it-defense.de\/it-defense-2027\/wp-content\/uploads\/sites\/8\/2026\/10\/Michael-Bruegge_Hoodie-1.png\">\r\n\t\t\t\t\t\t\t\t<div class=\"rg-overlay\"><\/div>\r\n\t\t\t<\/div>\r\n\t\t\t<div class=\"rg-name\">Michael Br\u00fcgge<\/div>\r\n\t\t<\/div>\r\n\t\t\t\t\t<div class=\"rg-card\"\r\n\t\t\t data-name=\"Nestori Syynimaa\"\r\n\t\t\t data-desc=\"Dr. Nestori Syynimaa is a Principal Identity Security Researcher at Microsoft Security Research.
