Welcome to the Cyber Nexus

Hi, I'm John, an IT Security Consultant with a focus on:

  • AI and Automation

As a proud OWASP member and advocate of open-source, this site serves as my personal hub for sharing:

  • Insights into cybersecurity trends

Passionate about IT security, I've created this site to:

  • Document my work and ongoing research
