About Us
Since 1998, the S2 Safety & Intelligence Institute has trained thousands of professionals in security risk management and public safety topics. Over the past 22 years, S2 has earned a reputation as one of the world’s premier sources for security and public safety training.
We provide classroom instruction and hands-on training at two regional schools in Florida, a series of joint-operated academies, and venue locations throughout the world. Through our sister company, the S2 Online Academy, we also deliver high quality distance education to students unable to attend live courses.
In addition to public courses, S2 provides private training and consulting assistance for a diverse range of corporations and government ministries.
