Recovering Sysadmin Turned Pentester

I'm a Senior Penetration Tester at SecurIT360, a Microsoft MVP, and the person behind Ethical Threat. My background in IT and systems administration gives me a unique defender's perspective combined with an offensive security mindset.

I specialize in Active Directory security, internal network penetration testing, and vulnerability assessments. When I'm not breaking into networks, I'm building open-source tools to help defenders secure theirs, writing about security, and hosting The Cyber Threat Perspective podcast.
