The PQC Network Scanner evaluates an organization's cryptographic exposure as it prepares for post-quantum security. It analyzes TLS endpoints for both classical and emerging quantum-safe algorithms, helping teams identify vulnerabilities and improve their security posture. The tool also provides detailed reports on endpoint configurations and offers guidance on migration to new standards.

Cloudflare is working to implement Post-Quantum (PQ) cryptography to secure the Internet against future quantum computing threats. The proposed Merkle Tree Certificates (MTCs) aim to reduce the size and complexity of TLS handshakes, addressing the performance issues posed by large PQ signatures. This shift is essential for maintaining security without degrading performance.
