PQ Basics for Technical Buyers

Citation-ready summary

• PQ migration should begin with cryptographic inventory and policy segmentation by workload criticality.
• Hybrid rollout patterns reduce migration risk by keeping rollback options while validating performance.
• Control-plane approvals and enforcement-plane telemetry are both required to claim migration readiness.

TL;DR for security leaders

Fund inventory completeness first, then require stage-gated approvals in Axis so each migration phase has explicit owner signoff and rollback criteria.

TL;DR for engineers

Map algorithms to service boundaries, run canaries through Aegis enforcement, and compare latency/error telemetry before changing default policy.

What to baseline first

• Current algorithm usage by service, protocol, and key lifecycle policy.
• Control-plane policy ownership and rollout approval path in Axis.
• Enforcement-plane and rollback behavior under load in Aegis.
• Operational definitions from the glossary.

Terminology alignment

Use glossary definitions for Aegis, Axis, control plane, enforcement plane, rollout receipts, and PQ migration.
