  • “We’re sharing lessons learned from Meta’s post-quantum cryptography (PQC) migration to help other organizations strengthen their resilience as industry transitions to post-quantum cryptography standards.
  • We’re proposing the idea of PQC Migration Levels to help teams within organizations manage the complexity of PQC migration for their various use cases.
  • By outlining Meta’s approach to this work — from risk assessment and inventory through deployment and guardrails — we hope to contribute practical guidance that helps accelerate the broader community’s efforts to move toward a post-quantum future.
  • Our goal is to help others navigate this transition effectively, efficiently, and economically so they can prepare for a future where today’s public‑key encryption methods may no longer be sufficient. […]”
