OPEN SOURCE TOOL
Know where you're still quantum vulnerable.
QuReddy is an open-source post-quantum readiness scanner that helps security teams identify TLS endpoints still relying on classical cryptography and highlights where hybrid post-quantum protection has already been deployed.
READY
PQ hybrid X25519MLKEM768 negotiated
Monitor: certificate and signature chain remain classical. Key exchange is hybrid post-quantum, but full quantum readiness also depends on post-quantum signatures.

Cipher Suite

The threat starts before quantum exists
Encrypted traffic captured today may still be valuable decades from now. Large adversaries can afford to store it and wait for the cryptography landscape to change. The quantum timeline is uncertain. The data retention timeline is not.
QuReddy identifies where you’re still relying on classical TLS and where hybrid post-quantum protection is already in place. One scan gives security teams a clear picture of what should be protected first.
