RTX

RTX is the world's largest aerospace and defense company, formed in 2020 through the merger of Raytheon Company and United Technologies Corporation, and rebranded to its current name in 2023. With roots stretching back to 1922 and more than 185,000 employees operating globally, the company delivers advanced systems and services spanning commercial, military, and government sectors - covering everything from seabed to space. The company's technical portfolio extends across aircraft engines, avionics, aerostructures, guided missiles, air defense systems, satellites, and drones. Within this sprawling domain, RTX develops and deploys cybersecurity solutions as a distinct product line, addressing threats across its aerospace and defense infrastructure. Given the company's scale and the criticality of its systems - many operating in contested or classified environments - cybersecurity work here likely intersects with aviation safety systems, weapons guidance, satellite communications, and government network defense. RTX's cybersecurity function operates within an organization that serves both commercial aviation customers and defense clients, meaning practitioners encounter threat models ranging from nation-state adversaries targeting missile systems to aviation safety requirements for commercial aircraft. The company's work inherently involves protecting operational technology, embedded systems, and complex supply chains across multiple security clearance levels. Christopher T. Calio serves as CEO, leading an organization headquartered in the United States with global operations.
