Historically, the gap between high-level protocol security proofs and their actual code implementations has been a subtle but critical attack surface — flaws in that translation can undermine even mathematically sound designs. By automating formal verification at scale, organizations can reduce reliance on costly manual audits and catch implementation errors before they reach production. This matters because messaging systems protecting millions of users are high-value targets, and post-quantum cryptography must be verified correctly now before quantum-capable adversaries emerge.
