Post-quantum cryptography (PQC) is coming—and for most organizations, the hardest part won’t be choosing new algorithms. It will be finding where cryptography is used today across applications, infrastructure, devices, and services so teams can plan, prioritize, and modernize with confidence. At Microsoft, we view this as the practical foundation of quantum readiness: you can’t protect or migrate what you can’t see. As described in our Quantum Safe Program strategy , cryptography is embedded in all modern IT environments across every industry: in applications, network protocols, cloud services, and hardware devices.

It also evolves constantly to ensure the best protection from newly discovered vulnerabilities, evolving standards from bodies like NIST and IETF, and emerging regulatory requirements.
