Post-Quantum AI Infrastructure Security: A Complete Guide for 2026

This blog post warns organizations that 2026 is a critical year for post-quantum readiness and that agentic AI architectures (notably Model Context Protocol servers) introduce high-risk attack surfaces—enabling threats like harvest-now-decrypt-later, tool poisoning, and prompt injection. It recommends a three-step strategy of discovery/inventory of MCP connections, crypto-agility with hybrid PQC/TLS deployments, and hardware-level protections (secure enclaves), plus AI-driven anomaly detection and compliance alignment to mitigate these risks.
