Suman Sedhai

Cyber Security Engineer ❖ CISSP ❖ Toronto

For over six years I have stood at the gates of the digital Kurukshetra — containing threats, hardening the chakravyuha of enterprise networks, and mentoring the next line of defenders. This is my chronicle, told in six parvas.

परित्राणाय साधूनां विनाशाय च दुष्कृताम्

“For the protection of the good and the destruction of wrongdoers” — a fair mission statement for a security engineer.

Bhagavad Gita · 4.8

पर्व I — Adi Parva

The Origin

Every epic begins with where the hero comes from — and what he swore to protect.

I'm a Cyber Security Engineer with over six years of experience safeguarding enterprise systems, reducing vulnerabilities, and optimizing security postures for global clients. With a Bachelor's in Electronics and Communication Engineering and a Post-Degree Diploma in Network Security, I blend technical depth with strategic risk management — aligning security with the goals of the kingdom it defends.

CISSP-certified, I thrive in fast-moving campaigns: leading incident response, mentoring junior analysts, and architecting cloud and on-premises security frameworks. When I'm not securing networks, I'm tinkering with Python, exploring AI/ML in threat detection, or volunteering as a technical mentor.

I also founded Graphene Magazine to spotlight IT innovation and mentor students in robotics and programming, and competed internationally at ABU Robocon, designing electromechanical systems and safety protocols.
