What we offer

ASTI currently offers two training programs. The integrated training course is designed to bring personnel in various departments across local, state and federal agencies together, to identify and respond to threats or emergency events. ASTI also offers specialty training programs that equip police, fire, and medical personnel for the unique professional challenges they face during emergency response.

Sessions typically include 20-30 participants, and are led by a team of instructors comprised of emergency response, security and first response teams with decades of experience in intelligence, tactical response and care, cybersecurity, and infrastructure protection.

ASTI trains participants in Israel for the duration of their program, combining unique, real-world curriculum, site visits and tactics with practical knowledge.
