We don’t teach quantum physics — we teach the operational consequences The core of the course is a structured cryptographic inventory exercise that participants do on their own environments, identifying every place RSA, ECC, and Diffie-Hellman currently live. From there we move into migration planning, vendor questionnaires that surface useful answers, and realistic timelines. Defense suppliers tend to underestimate how much of their cryptographic surface is buried in third-party components, which is where the inventory exercise pays off.
