Quantum Risk Explained

Quantum computing is advancing from theoretical research toward practical commercial deployment, creating security risks for current encryption and authentication systems. Cryptographically relevant quantum computers (CRQCs) could break public-key algorithms like RSA and ECC that protect internet communications, identity systems, and software supply chains. The threat is already present through harvest now, decrypt later activities, where adversaries collect encrypted data today to decrypt once quantum capabilities mature, and regulatory mandates are pushing organizations to adopt post-quantum cryptography by the mid-2020s to avoid compressed timelines and higher costs.

Why it matters: All organizations holding sensitive data, managing authentication, or relying on digital signatures face long-term exposure from harvest now, decrypt later attacks and eventual CRQC emergence; practitioners should begin post-quantum cryptography migration planning now to meet regulatory deadlines and avoid costly emergency transitions.
