About Me

Cybersecurity with a Purpose

Hello! My name is Manoj Kumar, a Cybersecurity professional with a deep passion for protecting both digital infrastructures and industrial environments. My journey blends a hacker's mindset with a defender's discipline.

I specialize in penetration testing, digital forensics, cybersecurity Instructor , and network security. Armed with certifications like CEH, WAPT, NPT, CCNA, and Python, I've engaged in everything from real-world cyberattacks to academic research and competitive hacking.

Notably, I've been recognized by the Government of India for disclosing critical vulnerabilities, featured in Inflectra's Hall of Fame, and celebrated as a 3× CTF champion and Hackathon finalist at IISc.

I also enjoy sharing knowledge — whether through public speaking, running workshops, or contributing tools like my custom network mapper PortXplorer.

"My mission is to build safer digital ecosystems and contribute to the security field."

If you're looking for someone who thrives on solving complex security challenges and making real-world impact — let's connect.
