Klaudia Kloc

Klaudia Kloc is CEO and Co-Founder of Vidoc Security Lab. An ethical hacker and security researcher, she combines hands-on offensive security experience with application security leadership. At BlockFi, she progressed from Security Engineer to Application Security Manager in just over two years. Previously, at Lufthansa Systems, she performed penetration tests and security code reviews, developed exploits and testing tools, and trained developers to write secure software.

Working across vulnerability research, exploitation and security architecture gave her firsthand insight into how real systems fail—and why traditional security approaches struggle to keep pace with modern development.

Together with Dawid Moczadło, she founded Vidoc Security Lab, a Silicon Valley startup building AI that finds real vulnerabilities in human- and AI-written code, validates the risk and proposes fixes. As CEO, she connects that technical foundation with a clear mission: making security keep pace with the software being built.

Klaudia is a Forbes 30 Under 30 honoree and has been named among the Top 100 Women in Engineering. Her speaking engagements include Stanford University, The Hack Summit, CAMLIS and ICCV, among others. She frequently gives interviews on cybersecurity, women in technology and the experience of women building companies in Silicon Valley, with appearances in Forbes Women Polska, Rzeczpospolita and 99 Twarzy AI. She and her work at Vidoc Security Lab have also been featured by Bloomberg, The Washington Post and CNBC.
