Area 51
iPhone
Apple's supply chain security rivals that of most intelligence agencies. The company maintains separate manufacturing facilities where workers produce components without knowledge of the final product. Employees caught leaking information face immediate termination and aggressive legal pursuit across international jurisdictions.
The iPhone's software architecture incorporates military-grade encryption that has successfully resisted federal court orders and prompted heated congressional testimony. Apple's refusal to create backdoors has been described by intelligence officials as a greater obstacle to surveillance than many purpose-built security systems.
