Dakota State University Online Cyber Defense, Ph.D.

Dakota State's Ph.D. in Cyber Defense is a 72-credit doctorate with online coursework, three on-site research seminars each year in Madison, South Dakota, and a total tuition of $39,510. It's built for working cyber professionals who already hold a master's and want research credentials. The yearly travel and the admission bar are the main hurdles.

Dakota State University is a public university in Madison, South Dakota, with a college focused on cyber. This Ph.D. covers its coursework entirely online, but the annual residency requirement includes three on-site research seminars on the Madison campus. That makes it online in the way most working adults need, with a real in-person component you must plan for each year.

The school also offers a Ph.D. in Cyber Operations, which is 61 credits and requires three residencies of about three days each over the whole program. Cyber Defense is 72 credits with seminars every year. If you want the lighter travel schedule and a shorter credit count, look at the Operations doctorate. If you want the Cyber Defense focus, expect more campus visits.

Start terms are fall and spring.

The full rubric is on the methodology page.

Coursework is delivered entirely online. Two start terms a year mean that if you miss the fall deadline you aren't waiting long. The full-time route finishes in about three years, while the part-time path can stretch up to seven.

The on-site seminars change the rhythm. You'll prepare for each visit, present or discuss research there, and return home with work to continue. That's closer to a traditional doctoral cohort than most online degrees offer.

Who It Fits

• Security leaders and engineers who hold a master's in cyber, data privacy, computer science or a technology-oriented field and want the doctorate for teaching, research or senior advisory roles.
• Professionals with a 3.0 GPA or higher from earlier degrees, which is the minimum the admissions page sets.
• Candidates drawn to data privacy or management work, two of the three concentrations the school lists.
• People who can arrange travel to South Dakota three times a year without disrupting a job.

Who Should Skip It

• Anyone without a master's degree in a related field, because both a bachelor's and a master's are required.
• Students who can't travel. The on-site seminars are part of the annual residency requirement, not an option.
• People who want a quick credential. Even full time, the program is designed around three years, and the part-time path stretches to seven.

The doctorate is 72 credits, with the three concentrations the school lists: Data privacy, Management and Technical fields. By name, Data privacy points toward compliance and information governance, Management toward people who lead security teams, and Technical fields toward those who stay close to systems and tools.

The research seminars are the backbone of the experience. Three each year gather students and faculty on the Madison campus, which is where cohort relationships form and where research directions get tested before you commit to one. Ask the department for sample dissertation topics from recent graduates so you can see what the finished work looks like.

Standout Features

• Coursework is offered entirely online, with three on-site research seminars each year

Online tuition and fees are $548.75 per credit for 2026 to 2027, which puts the 72-credit total at $39,510. For non-resident students taking computer science (CSC) courses, a delivery fee of $117.70 is added.

Travel is the cost the tuition figure leaves out. Three trips a year to Madison add up across a three-to-seven year timeline, so budget flights, lodging and time off alongside tuition. Ask your employer whether tuition assistance could cover part of it.

72 credits at $548.75 a credit comes to $39,510 in tuition, before fees.

The credential is a Ph.D. The GRE isn't required. Admission asks for a bachelor's and master's from an accredited institution in cyber, data privacy, computer science or a technology-oriented degree, with a minimum 3.0 GPA. Dakota State's master's in Cyber Defense carries an NSA Center of Academic Excellence in Cyber Defense designation; that designation is stated for the master's program.
