About Me

Dallas Haselhorst

Hello! My name is Dallas Haselhorst (hazel-horse). I have worked as a general IT and information security professional for far longer than I care to remember. In 2000, I received a PoliSci minor and concurrent bachelor degrees in Information Networking and Telecommunications (INT) and Computer Information Systems (CIS) from Fort Hays State University. Go Tigers! During my last few years of college and for several years after, I worked in healthcare IT. I then founded and co-owned a managed IT service provider until its acquisition in July 2016 . After assisting with the transition, it was time to move on.

I am currently a Master’s Degree candidate with the SANS Technology Institute (STI) in Information Security Engineering (MSISE). I hold numerous industry certifications including the CISSP, GSEC, GCIH, GCCC, GCPM, GPEN, GMON, and GCIA. When not working and/or finding new angles on infosec issues, I love learning and helping opensource projects. I enjoy tinkering with all things technology, helping others learn tech, collecting certifications like they are baseball cards, and spending time with my family.
