OpenSecurityTraining.info was started in 2011. It was relaunched as OpenSecurityTraining2 at https://ost2.fyi in 2021. OpenSecurityTraining is now also officially a 501(c)(3) charitable non-profit in the US. We are dedicated to creating the world's best cybersecurity trainings. That they're *free* is just a bonus!
Per-tab counts come from YouTube's public statistics. Only Videos and Playlists have exact public totals. Shorts is estimated from the most recent 25 uploads. Live, Podcasts, Courses, Posts and Store are shown when the tab exists — YouTube does not publish a public count for those.
