Marin Ivezic shows how to inventory and harden crypto before quantum computers break today’s defenses. SANS Emerging Threats Summit 2025 Quantum-ready now—regulators demand automated crypto inventories and rapid PQC plans. Marin Ivezic, Founder, Applied Quantum, details a step-by-step preparation blueprint. He forecasts cryptographically relevant quantum computers by the early 2030s and reviews U.S./EU mandates that already set deadlines for discovery and mitigation. Marin dissects why manual, interview-driven inventories fail, advocating tool-assisted scans plus targeted deep dives. He outlines hybrid stop-gaps, segmentation, tokenization and early PQC pilots to reduce risk while vendors catch up. Throughout, he stresses prioritizing long-lived secrets—operational tech keys, intellectual property, identity systems—and aligning board-level risk appetite with forthcoming NIST standards. Key Takeaways - Early-2030s CRQCs trigger “store-now-decrypt-later” urgency - Regulations require automated cryptographic discovery today - Tool-assisted scans beat manual interviews for accuracy & scale - Mix PQC, hybrid crypto and network controls for phased defense - Focus first on crown-jewel data with multi-decade confidentiality View upcoming Summits: #EmergingThreatsSummit #PostQuantumSecurity #QuantumThreat
