Hi, I'm Mario Santella – Security Researcher focused in OSINT and IT guy
With a solid background in IT and software development since 2012, I’ve gradually shifted my focus towards investigative cybersecurity, OSINT (Open Source Intelligence),
and digital threat analysis. My work sits at the intersection of security research, data-driven investigations, and strategic intelligence.
I help individuals, journalists, and organizations uncover digital traces, map risks, and stay ahead of threats in the open web and beyond.
I operate remotely from Italy and collaborate on research, recon, and intelligence-driven projects worldwide.
