About Megan Roddie-Fonseca

Megan Roddie-Fonseca is a cybersecurity professional and SANS Certified Instructor recognized for her expertise in digital forensics, threat hunting, cloud investigations, and detection engineering. She currently serves as a Senior Security Engineer at Datadog, where she advances cloud-forensics practices and develops practical detection systems. With a reputation for blending technical depth with accessibility, Megan is both a practitioner and an educator dedicated to strengthening the cybersecurity community.

Megan’s academic journey began early, enrolling in college at 14 while completing high school. By 21, she had earned a bachelor's degree in mathematics and a master’s degree in digital forensics from Sam Houston State University. Her passion for security was sparked through an internship at the Texas Department of Public Safety, which led to SOC, IR, and threat-intelligence roles at Recon InfoSec and IBM Security X-Force. She later advanced into senior engineering positions at IBM and Datadog. Megan went on to complete a second master’s degree in Information Security Engineering at the SANS Technology Institute, an NSA Center of Academic Excellence in Cyber Defense and multi-year winner of the National Cyber League competition, where she now serves as a faculty member.

As co-author of SANS FOR509: Enterprise Cloud Forensics and Incident Response, Megan draws on her experience at Datadog and IBM X-Force to shape the course’s hands-on labs and investigative scenarios. Her background in cloud forensics and detection engineering informs modules on AWS, Azure, and Google Workspace investigations, while her incident-response work against nation-state and cybercrime activity ensures students practice techniques that reflect challenges they will face in real-world enterprise environments. She is also the author of Practical Threat Detection Engineering. Beyond her professional and academic roles, Megan serves as CFO of Mental Health Hackers, where she advocates for mental wellness and inclusivity in cybersecurity.

Outside of work, Megan applies the same discipline to Muay Thai and Brazilian Jiu-Jitsu. Students consistently describe her as approachable, clear, and motivating, praising her ability to translate complex technical concepts into practical applications (feedback via SANS course evaluations). Her teaching philosophy emphasizes inclusivity and accessibility, with a focus on equipping the next generation of analysts with the skills and confidence needed to defend against evolving threats.
