CS50's Introduction to Cybersecurity (Harvard)
How systems get attacked and defended, explained for a general audience. Beginner cyber courses rarely carry a name like this.
- Computer Science
- Who can enter
- Anyone worldwide. No coding required; free to audit
- What it costs
- Free to take, and CS50 issues its own free certificate from cs50.harvard.edu. The paid one is the OPTIONAL edX verified certificate, and it is not cheap: roughly $200-300 depending on the course, with Harvard listing $219 for CS50 Python. You never need it. The course, the problem sets and the free CS50 certificate cost nothing.
- When it closes
- We could not confirm this year's date against the organiser's own page, so we are not showing a countdown for it. Last published: Self-paced online: enrol and start any time (free to audit).
Sending this to someone sends the four facts above, not just a name. They will see who can enter and what it costs before they decide.
