Fabian Bräunlein



Fabian studied IT Systems Engineering at Hasso Plattner Institute, afterwards joining SRLabs to contribute to IT security consulting projects, research and product development. Serving both startups and Fortune500 companies, Fabian has led projects ranging from penetration testing and red teaming to creating and implementing complete security roadmaps. His research includes hacks on payment terminals, travel booking systems and smart speakers, and was presented at top-tier security conferences and covered by international news. In the realm of product, Fabian was able to develop his side project, a vulnerability scanner, into SRLabs' first commercial SaaS product while building and leading a team of engineers to eventually take over.

Lukas  studied Computer Science at Karlsruhe Institute of Technology. In his later Security Engineering roles with Scout24 and Episerver, Lukas focused on securing every stage of the software development lifecycle; his specialties include conducting thorough white-box reviews of complex applications, as well as designing and implementing secure and efficient software architecture. While being especially well-versed in web and cloud, Lukas has also worked on security research targeting more niche technologies like telecommunication protocols. In addition to that, he has conducted red teaming exercises and a variety of other consulting projects during his time at SRLabs.
