ADecryption policyenables the NGFW to enhance visibility into encrypted traffic, including traffic that may use post-quantum cryptography (PQC). By decrypting SSL/TLS traffic, the firewall can analyze, block, and log the use of PQC and other advanced cryptographic methods.

Decryption policies ensure that all encrypted communications are inspected for malicious content, preventing attackers from hiding threats within encrypted traffic. This process allows administrators to enforce security and compliance while also gaining better insights into network activities involving PQC.
