Executive Summary

Quantum computers present a significant future risk to current cryptographic systems that protect sensitive data worldwide. According to cryptography experts, organizations may face years of transition to achieve quantum-safe security, and some systems may never be fully protected. The window of vulnerability is critical because adversaries are already harvesting encrypted data with plans to decrypt it once quantum computing capabilities mature. Organizations should begin assessing cryptographic inventory and planning migration strategies to post-quantum cryptography standards now to mitigate future risks.

Summary

Quantum computers are coming and may impact systems in unexpected ways, and it will "take years to be fully quantum-safe, if ever," cryptography expert warns.
