Test if your website supports post-quantum cryptography
Quantum computers pose a serious threat to current encryption methods. Our free PQC scanner instantly checks if your website supports NIST-standardized post-quantum cryptography algorithms including ML-KEM (Kyber) and ML-DSA (Dilithium).

Latest scans from all users. Sites are graded based on post-quantum cryptography support and TLS configuration.
Excellent security: PQC ready with TLS 1.3 only. Fully protected against quantum threats and downgrade attacks.
Good security: PQC ready but supports older TLS versions. Vulnerable to protocol downgrade attacks.
Needs immediate upgrade: No post-quantum cryptography detected. Vulnerable to future quantum computer attacks.
Post-quantum cryptography (PQC) refers to cryptographic algorithms that are designed to be secure against attacks from quantum computers. As quantum computing advances, current encryption methods like RSA and ECC may become vulnerable.
Quantum computers could break current encryption within years. Migrating to PQC now protects your data from future threats.
Combines classical and post-quantum algorithms for security today while preparing for quantum threats tomorrow.
NIST has standardized ML-KEM, ML-DSA, and SLH-DSA for post-quantum key exchange and signatures.
