Hey y’all, I’m Chris Sanders and I’m a cyber security author, analyst, and instructor.

Welcome to my website and blog. Here I write about topics related to defensive cyber security and where it intersects with cognitive psychology and education. I also share updates about my publications and classes. You’ll find links to my books, papers, blog entries, and training classes in the menu above.

I’m the founder of Applied Network Defense, a practitioner-focused training company dedicated to providing high quality, affordable security education.

I also founded and direct the Rural Technology Fund, a non-profit organization focused on providing STEM education opportunities to children in rural areas.
