Expert Recommends: Prepare for PQC Right Now

**Executive Summary:** This article warns that adversaries are collecting encrypted data today to decrypt later with future quantum computers and urges immediate action to migrate to post-quantum cryptography (PQC); it presents a five-step migration framework (Preparation, Diagnosis, Planning, Execution, Continuous Monitoring), catalogs organizational, PQC, and code/documentation challenges, and recommends pragmatic measures such as hybrid cryptography, cryptographic agility, vendor coordination, training, and phased rollouts to preserve long-term data confidentiality.
