Microsoft has announced the Quantum Safe Program, a comprehensive, multi-year roadmap designed to prepare its software, infrastructure, and ecosystem for the era of quantum computing threats.
The initiative aims for early adoption of post-quantum cryptography (PQC) as soon as 2029, with a full transition across Windows, Azure, Microsoft 365, and AI services by 2033, two years ahead of most government timelines.
The program is built on three priority pillars: securing Microsoft’s infrastructure, empowering customers and partners to adopt quantum-safe solutions, and driving global standards for quantum-safe cryptography.
To launch this transformation, Microsoft has already integrated PQC algorithms such as ML‑KEM and ML‑DSA into foundational libraries like SymCrypt and enabled hybrid key exchange in alignment with emerging IETF standards.
The rollout follows a phased approach, starting with core cryptographic frameworks, extending to infrastructure services like authentication and key management, and eventually encompassing all endpoints and services.
Microsoft’s initiative aligns with public-sector guidance from agencies like NIST, CISA, and OMB, and represents a proactive strategy to guard against “harvest now, decrypt later” attacks as quantum computing advances.
