About Petre Radu Cătălin
Full biography of Petre Radu Cătălin (Petre Radu) - offensive security professional focused on penetration testing, research, and practical security evaluation. Based in Brașov, Romania.

01. Foundations
Petre Radu Cătălin is an offensive security professional based in Brașov, Romania, currently working as a Penetration Tester at NTT DATA. His work focuses on practical assessment of web applications, infrastructure, and security controls, with attention to how real weaknesses can be exploited and remediated.
02. Education
He is currently pursuing a Master's degree in Cyber Security at Universitatea Transilvania din Brașov (2024-2026), building on a Bachelor's in Renewable Energy Systems completed there between 2020 and 2024. His studies include cyber defense, ethical hacking, cryptography, secure software development, and applied security analysis.
03. Training and research
Petre has participated in Google.org Cybersecurity Seminars, worked through security labs and CTF-style exercises, and developed hands-on practice with tools such as Wireshark, Burp Suite, Splunk, Wazuh, and Suricata. That mix of academic study and practical training shapes how he approaches testing and reporting today.
04. Current work
At NTT DATA, he performs penetration testing on production systems and provides findings in a way that connects technical risk with actionable remediation. Outside of that role, he also continues security research through bug bounty work on Intigriti and HackerOne, focusing on real-world exploitability and responsible disclosure.
05. What I stand for
His approach is practical and evidence-based: identify the issues that matter, explain the risk clearly, and help teams move from vulnerable to defended with a realistic remediation path. That mindset is at the center of his offensive security work.
Personal Mission
To identify critical vulnerabilities and deliver actionable defense - helping organizations understand their real exposure before attackers do, and to raise the bar for security practice in Romania and beyond.
