Nagra audio equipment, professional recording devices, and digital security software solutions originate primarily from Switzerland, reflecting the country's celebrated legacy of high-precision engineering and mechanical craftsmanship. The iconic Nagra professional analog and digital audio recorders were originally developed in Lausanne, Switzerland, by engineer Stefan Kudelski, establishing a global reputation for unmatched fidelity used in cinema and espionage. Simultaneously, the modern Nagra digital television and content protection technologies—operated under the Kudelski Group—are researched, engineered, and managed out of corporate and technical facilities located in Switzerland, alongside international software development and support hubs spanning Europe, Asia, and the Americas.
