Blind Spots by Design: Defending Visibility During Post-Quantum Rollouts
People often think of post-quantum migration as just a standards task: list the algorithms, add new libraries, update certificates, and move forward. But in reality, operational issues are usually the first to cause problems. In this briefing, I�ll share a controlled TLS/PKI migration pilot that shows what really happens when post-quantum and hybrid methods are used in production, especially with certificate lifecycle, handshake size, network paths, monitoring, and rollback.I�ll explain the pilot�s architecture, how we compared the baseline to the migrated setup, and the main types of failures we found. These include handshake expansion that leads to fragmentation and retransmission, changes in CPU and memory use at endpoints and gateways, issues with trust stores and certificate paths, unexpected behavior at intermediaries, and problems with security monitoring visibility. I�ll also show how practicing rollbacks can reveal hidden dependencies that standard cryptographic checks often miss.The session is built around evidence, like packet captures, benchmark results, configuration changes, and telemetry from the migration tests. I�ll finish by sharing a set of quality checks, tested in the field, to help teams decide if a post-quantum change is truly ready. This isn�t a basic introduction to PQC. Instead, it�s a practical, engineering-focused look at why quantum-safe deployments fail, how to spot problems early, and how to migrate without disrupting production.
