About Me

Cybersecurity leader with extensive expertise in penetration testing, web application security, and red team operations

Landon Mayo - Cybersecurity Expert

Landon Mayo

I'm a seasoned IT professional with 25 years of experience, including 22 years specializing in penetration testing. As the former OWASP Houston Chapter Leader (2012-2014) and an OWASP Trainer, I bring a wealth of knowledge in offensive security operations.

My qualifications derive from four core pillars: military training and discipline as a U.S. Air Force Veteran (7.5 years), rigorous industry certifications, decades of hands-on experience at the highest levels, and recognized authorship contributions to the global application security community.

My formal education includes 42 competency units in the Cybersecurity program at Western Governors University (WGU), designated by NSA/DHS as a National Center of Academic Excellence in Cyber Defense. Additionally, I have completed 19 continuing education certificates focusing on the intersection of AI/ML and offensive security.
