I am a Security Engineer (MSc) and a Qualified Ethical Hacker. I have more than 10 years of design and operation and security experience in the field of IT. My main area of expertise is cyber security, where I have been involved in vulnerability testing of IoT devices and software, digital signature and PKI systems, and network security, especially for multinational companies and SMEs. The experience and knowledge gained from year to year has led to the fact that continuous development is extremely important to me, which is why I am currently studying at the Doctoral School of Security Sciences of the University of Óbuda.
