QuReddy is an open-source post-quantum readiness scanner that helps security teams identify TLS endpoints
still relying on classical cryptography and where hybrid protection is already in place.

Monitor: the certificate and signature chain remain classical.
Key exchange is hybrid post-quantum, but full quantum readiness also depends on post-quantum signatures.

The threat starts before quantum exists
Data intercepted now remains a goldmine for future decryption. Major threat actors are harvesting current traffic to exploit once quantum power matures. While the quantum arrival is unknown, the shelf life of your data is permanent.
