PQC Layer 1: Where Does Your Encryption Actually Live?

Stop treating cryptography as a single IT patch. It’s a distributed business risk. In this deep dive, we explore Layer 1 of the PQC Strategic Architecture: Enterprise Cryptographic Domains. Before an organization can migrate to Post-Quantum Cryptography (PQC), it must first map the battlefield. We aren't just talking about software updates; we are talking about the fundamental fabric of your enterprise security. From the immediate "Harvest Now, Decrypt Later" (HNDL) threat targeting your network traffic to the physical limitations of your Hardware Security Modules (HSMs), we break down the five critical domains you must inventory and assess today. In this video, we cover: Domain 1: Data in Transit – Why your network is the epicenter of the HNDL threat. Domain 2: Identity & PKI – Why a quantum breach of your "Front Door" collapses Zero Trust. Domain 3: Applications & Code – Dealing with "Crypto-Rigidity" and hardcoded vulnerabilities. Domain 4: Hardware & Root of Trust – Assessing the physical compute capacity of your HSMs and KMS. Domain 5: Data at Rest – Why symmetric encryption (AES-256) is your "safest" bet, but still at risk.
