How Organizations Can Make a Successful Transition to Post-Quantum Cryptography (PQC)
Zscaler, Thursday, February 5th, 2026
The Quantum Era is fast approaching-and the eventual threat is no longer a distant concern: quantum computers will change our digital world because algorithms like Shor's break the public-key cryptography that currently underpins digital security.
The most immediate danger isn't that a quantum computer will appear overnight. It's the "Harvest Now, Decrypt Later" (HNDL) attacks that are likely already happening. Malicious actors are siphoning off encrypted data today: they can store it and wait for the day a quantum computer can unlock its secrets. For data with a long shelf life-trade secrets, government intelligence, healthcare records, financial data-the vulnerability is present now.
The good news is that the path forward has become clearer.
