As the predicted “Q-Day” approaches—the point at which quantum computers can break widely used public-key encryption—organizations across government, finance, cloud, and enterprise IT are racing to harden their infrastructure. While estimates vary, NSA and NIST project Q-Day could arrive as early as 2033, forcing enterprises to rethink their approach to cryptographic security. The most immediate threat isn’t just future decryption—it’s the “harvest now, decrypt later” (HNDL) strategy already used by cybercriminals and nation-state actors. Sensitive data stolen today under RSA-2048 or ECC encryption could be decrypted once quantum computers reach sufficient scale, exposing everything from financial transactions to government secrets.
