With NIST's post-quantum cryptography standards finalised and the NSA's CNSA 2.0 deadline requiring all new National Security System acquisitions to be quantum-resistant by January 2027, the migration window for enterprise and federal contractor environments is closing fast. Most organisations have yet to inventory their cryptographic assets, let alone begin migration.
Proton Mail's post-quantum encryption launch is another data point in an accelerating migration across email, messaging, and enterprise security platforms. The industry debate has shifted from 'should we?' to 'how urgent is the harvest-now-decrypt-later threat?' For most organisations the answer is more urgent than their current roadmap reflects — because the data being generated today has a longer confidentiality requirement than the planning horizon that informs most security investment decisions.
