Analyze TLS configurations for hybrid Post-Quantum Cryptography support.

Why is PQC Needed?

The advent of large-scale quantum computers poses a fundamental threat to the encryption systems that protect the modern internet.

01

Quantum Supremacy

Shor's algorithm allows quantum computers to efficiently factor large integers, breaking RSA and Elliptic Curve cryptography that secures 99% of today's web traffic.

02

Harvest Now, Decrypt Later

Adversaries are currently capturing encrypted data packets and storing them, waiting for future quantum computers to decrypt them and expose sensitive long-term secrets.

03

NIST Standardization

Global standards bodies like NIST have already finalized PQC algorithms. Organizations must transition to hybrid-PQC models now to ensure long-term data durability.

The Road to Y2Q

Post-Quantum Cryptography is not a future-proofing luxury—it is an urgent operational requirement to defend against immediate risks.

Context & Core Threat

Any encrypted document, financial transaction, or intelligence communication sent over the public internet today is vulnerable. Eavesdroppers capture and store large volumes of classical TLS traffic. While safe from current computers, these long-term secrets will be fully decrypted retroactively the moment a quantum computer is online.

Core Takeaway

If your data needs to remain secret for 5+ years, classical encryption is already unsafe.

Enterprise Migration Roadmap

Quantum Readiness Audit

Track your organization\'s preparedness. Select the milestones your engineering team has completed to receive your PQC security rating.

Scan & Audit Public Endpoints (Domain Check)

Critical

Identify external-facing TLS handshakes, APIs, CDN configurations, and public certificates that still rely entirely on classical ECDHE or RSA key exchanges.

Inventory Internal Crypto Assets & Libraries

Required

Document internal microservice communication libraries, Databases, Hardware Security Modules (HSMs), and Certificate Authorities that hardcode RSA/ECDSA.

Deploy Hybrid PQC Exchange in Staging

Recommended

Set up staging environments utilizing hybrid standards (e.g. X25519 + ML-KEM) to test client compatibility, latency, and packet fragmentation resilience.

Production Migration & Compliance Transition

Required

Roll out FIPS-compliant ML-KEM algorithms to production environments, deprecating legacy classical algorithms according to compliance standard schedules.
