The faculty of the online University of Wisconsin Master of Science in Cybersecurity is one of its greatest strengths. You won’t find another cybersecurity program—online or otherwise—that brings such diverse expertise together in one place. That’s because the MS in Cybersecurity program is a collaboration among Wisconsin Online Collaboratives and eight University of Wisconsin institutions: UW–Green Bay, UW–La Crosse, UW–Oshkosh, UW–Parkside, UW–Platteville, UW–River Falls, UW–Stevens Point, and UW–Superior. Each faculty member brings a unique background of industry experience and education to the program offering students a truly multidisciplinary experience.
