About Me.
Senior Cyber Security Analyst & Ethical Hacker
They say the best way to catch a hacker is to think like one. Well, I've been thinking like hackers since I accidentally "fixed" my school's firewall in 2008 (sorry, Principal Johnson). Now I do it legally and get paid for it – which my mom finally understands after explaining it 47 times.
With over 8 years in the trenches of cybersecurity, I've helped Fortune 500 companies sleep better at night while keeping their data safe from the digital boogeyman. I've stopped ransomware attacks, hunted APTs, and yes, I've seen "password123" used by a CEO more times than I'd like to admit.
When I'm not breaking into systems (ethically!), you'll find me contributing to open-source security tools, mentoring the next generation of white hats, or explaining to my relatives at Thanksgiving that no, I cannot "hack Facebook" for them.

Marcus found vulnerabilities in our system that three previous security firms missed. He then explained them to our board in a way that didn't put anyone to sleep. Worth every penny.
David Morrison
CTO, TechVentures Inc.
After the ransomware attack, Marcus was our first call. Within hours, he had contained the threat and was roasting our password policy. 10/10 would get roasted again.
