Explores practical cybersecurity and post-quantum cryptography, helping security professionals, developers, and technical leaders understand where quantum risk is real, what systems are affected, and how to prepare through cryptographic agility. This video explains why quantum computers will not break every security control at once—but why RSA, Diffie–Hellman, and elliptic-curve cryptography require serious migration planning.
