As quantum computers become more powerful, the “Harvest Now, Decrypt Later” threat has reached a fever pitch. Hackers are currently stealing encrypted data with the intent to unlock it once a “Cryptographically Relevant Quantum Computer” (CRQC) exists.
The PQC Transition
To combat this, 2026 has become the year of the Quantum Audit. Enterprises are scanning their entire digital footprints to identify where vulnerable RSA and ECC encryption is used. They are replacing these with Post-Quantum Cryptography (PQC) algorithms—mathematical problems that even a quantum computer cannot solve efficiently.
Hybrid Security
The transition isn’t an “overnight switch.” Most organizations are adopting a hybrid approach, layering traditional encryption with PQC. This ensures that even if a flaw is found in the new quantum-resistant algorithms, the data is still protected by the “old” math, and vice versa. For any business handling long-term data (like 30-year mortgages or medical records), being “quantum-ready” is now a legal and ethical requirement.
