Ing. Andrej Šebeň

I am a highly skilled ethical hacker with a strong track record in cybersecurity. I specialize in penetration tests, vulnerability assessments, and security controls. My experience lies in identifying and mitigating risks to protect critical assets. I can help your company enhance its security posture and defend against cyber threats.

Ing. Marek Mlynček

Co-Founder & Ethical Hacker

I specialize in offensive information security - penetration testing, web application testing, social engineering, and developing custom security tools. I've been active in the field of cybersecurity for over 5 years, with additional experience as a SOC analyst. I approach every project with a practical mindset, precision, and a focus on real-world risks. The result is clear, understandable reports with specific recommendations.

With over 5 years of experience in cybersecurity, I specialize in cloud security, penetration testing, configuration audits, and security assessments. I have worked extensively as a penetration tester in the banking, insurance, and telecommunications sectors, and have led teams on various projects.

Ing. Adam Žilla

Ethical Hacker

I'm a cybersecurity enthusiast with a strong focus on offensive security. Throughout my career, I've held various positions - from computer administration to security auditor, security analyst, and ethical hacker. For a period of time, I also worked in security as a pre-sales consultant, where I gained in-depth knowledge of how modern firewalls operate. I hold several certifications, including OSWE, PenTest+, CCSA, CCSE, CCTA, CCTE, CCSM, CCSI, and a Level II Personal Security Clearance. As an instructor, I've delivered multiple training sessions and lectures. I was the winner of the 3rd edition of the EY Cyber Security Trophy in the EY ESO DNA Born Ethical Hacker category, and I'm also a member of the winning team of the Guardians 2025 competition.
