Post-quantum cryptography is no longer a future planning track for federal buyers. Executive Order 14409 turns it into a deadline-driven compliance program, with agency owners, inventories, and procurement rules that push the change into vendor roadmaps, not just internal IT plans.
Federal agencies must name a migration lead, inventory high-value assets and high-impact systems, and move to PQC for key establishment by December 31, 2030 and digital signatures by December 31, 2031. The order also sets a 2027 pilot and pulls federal contractors into NIST FIPS compliance, including PQC-aligned algorithms and cryptographic vulnerability disclosure updates.
The practical shift is that crypto inventory, documentation, and product changes now have to line up with contracting timelines. For vendors selling into government or critical infrastructure channels, the federal schedule is likely to cascade into procurement checks long before the final dates arrive.
