It’s time to get serious about post-quantum security. Here’s where to start.

The article warns that advancing quantum computing could soon break widely used cryptographic standards (e.g., RSA/ECC), creating a potential “Q‑Day” and enabling “harvest now, decrypt later” attacks; it urges organizations to treat the threat as a board-level concern, inventory and prioritize sensitive assets, adopt NIST-standard post-quantum algorithms (potentially in hybrid deployments), shorten key lifetimes, automate PKI/PQC rollouts, and coordinate cross-organizational planning to protect long-lived data.
