About

I’m the Co-Founder and Managing Director of DAVISEC GmbH, a Vienna-based cybersecurity company specialized in penetration testing, adversary simulation, cloud security, and security awareness. My background spans both hands-on offensive security and real-world consulting. Before founding DAVISEC, I worked in the penetration testing division of a Big4 firm, focusing on red teaming, Azure/M365 assessments, web application security, Active Directory exploitation, and cloud attack paths. Today, I help companies strengthen their security posture through a combination of technical expertise, practical threat analysis, and clear communication. I’m particularly passionate about: Realistic offensive security testing (Web, AD, Cloud, Mobile, Red Teaming) Threat-driven security and understanding how attackers actually operate Creating practical security assessments that deliver real value, not just reports Building awareness programs that help people recognize modern social-engineering and deepfake risks Developing tools, automations, and custom security solutions for our clients At DAVISEC, we continuously work on new ways to combine technical excellence with approachable, customer-focused security — from hands-on pentests to training, incident-readiness, and modern compliance requirements like NIS2. If you're interested in strengthening your security or collaborating on a project, feel free to reach out.
