A New Era in Quantum Security Assessment: Check Any Domain for Post-Quantum Cryptography Support
Today, we’re excited to announce the launch of our free PQC Domain Checker, a powerful tool that allows anyone to test whether a domain supports Post-Quantum Cryptography in just seconds. This marks a significant milestone in making quantum security assessment accessible to organizations worldwide.
The Challenge: Invisible Quantum Vulnerabilities
As quantum computers advance toward cryptographic relevance, organizations face a critical challenge: how do you know if your infrastructure is quantum-safe? Traditional security audits don’t reveal whether your encryption is vulnerable to quantum attacks, and manual TLS inspection requires specialized expertise.
The threat of “Harvest Now, Decrypt Later” attacks means adversaries are already collecting encrypted data today to decrypt it once quantum computers become available. This makes PQC adoption not just a future concern, but an immediate security imperative.
What Makes Our PQC Checker Unique
Our tool leverages cutting-edge technology to provide accurate, real-time PQC detection:
Advanced Detection Technology
Unlike simple TLS version checks, our checker performs deep analysis of the key exchange negotiation process. We use OpenSSL 3.6.0 with native ML-KEM support to inspect TLS 1.3 handshakes and identify quantum-resistant algorithms including:
- X25519MLKEM768 - The hybrid algorithm adopted by Cloudflare, Google, and Facebook
- SecP256r1MLKEM768 - Microsoft’s preferred hybrid approach
- ML-KEM (512/768/1024) - NIST-standardized quantum-resistant algorithms
Serverless Architecture for Global Scale
Built on AWS Lambda with custom-compiled OpenSSL layers, our infrastructure delivers:
- Sub-3-second response times from anywhere in the world
- Enterprise-grade reliability with automatic scaling
- Zero configuration required - just enter a domain and get instant results
Comprehensive Results
For each domain checked, you receive:
- PQC Status: Clear indication of quantum-resistance support
- Key Exchange Algorithm: Specific cryptographic methods in use
- TLS Version: Protocol version information
- Detection Method: Transparency into how results were determined
- Actionable Recommendations: Next steps based on your results
Early Adoption Insights
Since launching our internal beta, we’ve analyzed thousands of domains and uncovered fascinating trends:
Tech Giants Lead the Way
Major technology companies have already implemented PQC:
- Cloudflare: ✅ X25519MLKEM768 enabled
- Google: ✅ X25519MLKEM768 enabled
- Facebook: ✅ X25519MLKEM768 enabled
- Meta Services: ✅ Quantum-ready infrastructure
Critical Sectors Lag Behind
Alarmingly, many organizations in highly regulated industries show no PQC support:
- Financial Services: Most major banks remain vulnerable
- Healthcare Providers: Limited PQC adoption despite HIPAA concerns
- Government Agencies: Slow migration despite NSA recommendations
- E-Commerce Platforms: Mixed results across major retailers
This gap highlights the urgent need for comprehensive PQC readiness assessments in these critical sectors.
Why This Tool Matters for Your Organization
Immediate Risk Assessment
Understanding your current PQC posture is the first step toward quantum security. Our tool provides instant visibility into whether your:

The Technology Behind the Scenes
Hybrid Detection Methodology
Our checker employs a multi-layered detection approach:
- Primary Detection: OpenSSL-based TLS 1.3 group negotiation analysis
- Fallback Verification: Node.js TLS library for cipher suite inspection
- Pattern Matching: Keyword analysis for PQC algorithm identifiers
- Validation: Cross-reference multiple detection signals
This redundancy ensures accuracy rates exceeding 99% for PQC detection.
Privacy-First Design
While we collect anonymized analytics to track global PQC adoption trends, we:
- Never store the actual domains you check
- Anonymize all IP addresses before logging
- Auto-delete historical data after 365 days
- Provide transparent data handling in our privacy policy
Using the PQC Checker
Getting started takes just seconds:
- Visit quready.com/check
- Enter any domain name (e.g., yourcompany.com, your-bank.com)
- Review instant results with detailed technical information
- Take action based on personalized recommendations
No registration, no credit card, no installation required.
What Your Results Mean
✅ PQC Enabled
If your domain shows PQC support, congratulations! You’re ahead of the curve. However, consider:
- Comprehensive Assessment: A single domain doesn’t represent your entire infrastructure. Schedule a full audit to evaluate all systems.
- Algorithm Updates: Ensure you’re tracking NIST PQC standards for future algorithm updates.
- Ongoing Monitoring: PQC configurations can change with infrastructure updates.
⚠️ No PQC Support
If your domain lacks PQC support, you’re not alone—but action is needed:
- Understand the Risk: Your encrypted data is vulnerable to quantum attacks
- Plan Migration: Begin implementing PQC before Q-Day arrives
- Assess Infrastructure: Identify all systems requiring quantum protection
- Set Timeline: Regulatory mandates and security needs should drive urgency
