Hello, I'm
Kshitij Nigam
Strategic Security Leader
With over 14 years of experience (since 2012), I specialize in protecting global cloud ecosystems, architecting centralized Vulnerability Management Systems, and building high-throughput security automation. Currently focused on implementing AI security frameworks (Shannon, CAI, Strix) using local LLMs for autonomous vulnerability discovery.
About Me
I am an Offensive Security Engineer and Technology Enthusiast based in Vienna, Austria. I've loved breaking things since I was 13 — hacking my RAM and reverse-engineering games to run on a low-end PC.
With over a decade of professional experience spanning software development, quality automation, and cybersecurity, I currently focus on leading offensive security initiatives, securing AI portfolios, and implementing AI-powered security frameworks using local LLMs.
Through the Nigamelastic YouTube channel and my Cybersecurity Hub, I share practical learnings, research, and technical walkthroughs to help others grow their cybersecurity skills.
Change is inevitable but being prepared for it is a choice!
