Right now, somewhere, an adversary is copying your encrypted VPN traffic. They can't read it today. They're saving it — for the day a quantum computer can crack it open. It's called "harvest now, decrypt later," and in 2026 it stopped being a thought experiment. This episode breaks down the post-quantum migration for people who actually run networks. What you'll hear: • The three NIST post-quantum standards (ML-KEM for key exchange, ML-DSA + SLH-DSA for signatures), finalized August 2024 • What "harvest now, decrypt later" means and why 5+ year data is already exposed • The expert-odds jump — 34% to 49% in one year — that a code-breaking quantum computer arrives within a decade • Cisco's real ship dates: Quantum Ready Assessments (July), IOS XE PQC for SD-WAN (August), default quantum-safe secure boot, majority of portfolio by December • Where it  ...
