CHRIS NELLINGER

Founder & Lead Security Consultant

I'm Chris Nellinger, the mind behind BlackCat InfoSec. I specialize in ethical hacking and offensive security — legally and methodically breaking into systems to expose vulnerabilities before malicious actors do.

In an age where cyber threats evolve by the hour, organizations need more than firewalls. They need someone who thinks like an attacker but works on their side. That's where I come in. Every engagement I take on is governed by strict rules of engagement, full legal authorization, and a commitment to making your infrastructure bulletproof.

Whether it's a Fortune 500 company or a growing startup, I bring the same intensity: find every crack, document every weakness, and fortify every defense.
