Post-Quantum Cryptography: The Clock Has Already Started
Commvault, Thursday, July 9th, 2026
Commvault urges organizations to start post-quantum cryptography preparation now, citing harvest-now-decrypt-later risk.
This article discusses the urgency of preparing for post-quantum cryptography, arguing the time to start is now rather than waiting for quantum computers to become commercially viable.
The primary challenge is not the technology but discovery, as most organizations lack complete visibility into their cryptographic infrastructure across applications, certificates, and third-party services.
A critical threat is harvest-now-decrypt-later attacks, where adversaries steal encrypted data today to decrypt once quantum capabilities mature, putting sensitive long-term data at immediate risk.
