Preparing for Q-Day: How Cloudflare is Helping DoD Achieve Post-Quantum Cryptographic Resilience Today

The transition to Post-Quantum Cryptography (PQC) is not a distant concern; it is an operational imperative for the Department of Defense (DoD) and the broader Intelligence Community (IC). Nation-state adversaries and other sophisticated actors are actively developing quantum computing capabilities that will render today's standard public key cryptography (PKC), including widely used algorithms like RSA and Error-Correcting Code (ECC), mathematically obsolete.

These algorithms rely on complex factoring problems that classical computers struggle to solve; however, quantum computers running Shor's and other algorithms can theoretically break through orders of magnitude faster. Regulatory bodies, including NIST, CISA, the NSA and international partners, have aligned on a clear timeline: classical cryptographic algorithms must be deprecated by 2030 and disallowed by 2035. In this Tech Spotlight, you will discover key benefits such as:

• Website and Application Protection
• Origin Server Protection via Cloudflare Tunnel
• Zero Trust and Remote User Protection
• Network-Level Protection via WAN and IPsec Tunnels
