7. The Daily Security Tip
It’s not exactly a class or an educational institute, at least by conventional standards. What The Daily Security Tip is, though, is an email-based learning tool produced by Heimdal Security that sends you a nugget of cybersecurity-related advice every day, with the ultimate goal of making you safer both online and off.
It’s completely free to sign up, and the creators of The Daily Security Tip claim that “there’s a 96% chance you’ll enjoy it”.
