About Me
Future CISO | Cybersecurity Professional | Purple Team Passionate
Hello! I'm Petras Guilherme Kulyumba, a passionate cybersecurity professional specializing in both offensive (Red Team) and defensive (Blue Team) security operations. With certifications in Certified Ethical Hacker (CEH) and CompTIA Security+, and currently pursuing CySA+ and ISC2 CC, I'm committed to mastering threat detection, incident response, and Security Operations Center (SOC) workflows.
My interest in cybersecurity stems from a deep curiosity about how systems are attacked and defended. I bridge the gap between Red and Blue teams a true Purple Team approach, leveraging offensive tactics to strengthen defensive strategies. My goal is to become a Chief Information Security Officer (CISO) and help organizations build secure and resilient infrastructures.
