Post-Quantum Cryptography (PQC) addresses the growing cybersecurity risks posed by quantum computers, which could eventually break the classical encryption methods used in protocols such as TLS, SSH, and IPsec. Organizations are already vulnerable to “harvest now, decrypt later” attacks, where encrypted data is intercepted and stored for future decryption once quantum computing capabilities mature. In response, governments and standards bodies are driving the adoption of PQC, with NIST advancing standards such as ML-KEM and ML-DSA. To help organizations prepare, Zscaler and HCLTech have introduced a joint PQC offering that combines Zscaler’s quantum-ready security capabilities with HCLTech’s expertise in assessment, planning, and implementation. The solution provides visibility into crypto
