INSIDER began as an in-house project when DSF’s founding partners Jonathan Shih and Frank Arispe saw a large training void within the private security industry. Across the country, security officers and professional bodyguards needed to be better trained in mindset, combative science, firearms proficiency, weapons manipulation, tactics, patrol procedures, and planning and implementing protective details. Retired military personnel and law enforcement officers also needed a no-nonsense way to transition their advanced training to a civilian context and/or acquire additional training to help them succeed in the private sector. Thus, INSIDER was born.
