Are Systems Ready for Quantum-Resistant Cybersecurity?
Analytics Insight, Tuesday, October 20th, 2026
Harvest-now-decrypt-later threats mean firms should inventory cryptography, prioritize sensitive data and plan phased PQC migration.
Quantum computing could eventually break widely used public-key encryption, putting long-lived business data and communications at risk.
The article explains the harvest now, decrypt later threat, in which attackers store encrypted data today to decrypt once quantum machines mature, a particular concern for finance, healthcare, technology and government contractors.
It compares post-quantum cryptography, stronger symmetric encryption and quantum key distribution, each with benefits and limits.
To prepare, organizations should inventory cryptographic assets, identify vulnerable systems, prioritize sensitive data, test quantum-resistant algorithms and build phased migration plans.
