PQC Server Profile — Reference

● HYBRID READY

This is the same hardening pattern we deploy for clients: classical + post-quantum key exchange for production TLS 1.3 stacks.

X25519 · classical ECDH+ML-KEM 768 · FIPS 203→Hybrid session key

An attacker must break both layers. A quantum computer that defeats X25519 still faces ML-KEM 768. Dual-layer protection, zero downtime migration.

01 · Why PQC

What is post-quantum cryptography?

PQC replaces RSA and ECC — breakable by Shor's algorithm on a future large-scale quantum computer — with lattice-based, hash-based, and code-based algorithms that neither classical nor quantum computers can efficiently solve. The standards are final. The migration window is open now.

🔐

Harvest now, decrypt later is real

Adversaries capture encrypted traffic today to decrypt once a fault-tolerant quantum computer arrives. Data with 5–10 year sensitivity is already exposed.

🧬

Hybrid = safe migration

We deploy X25519 + ML-KEM 768 in parallel. You keep classical compliance and gain quantum resistance — no flag day, no rip-and-replace.

📜

Compliance is converging

NIST FIPS 203/204/205 are published; CNSA 2.0 timelines require PQC adoption. Early movers avoid the last-minute scramble and audit failures.

02 · The quantum threat

Measured risk. Not hype.

Grover's and Shor's algorithms collapse the effective security of classical crypto. ML-KEM steps well beyond the estimated quantum-feasible threshold.

Projected timeline

2026 — Hybrid deployment beginsEarly adopters ship X25519MLKEM768 in TLS 1.3.
2030 — NIST PQC widely adoptedCNSA 2.0 milestones push federal & regulated suppliers.
2035 — 50% probability RSA-2048 falls*Global Risk Institute / BCG consensus window 2024–2038+.
2040+ — Widespread quantum threat to PKIEverything not migrated is in the global risk period.
⚠️ Harvest Now, Decrypt Later — Mosca's theorem: if X (time data must stay secret) + Y (migration time) > Z (time until quantum break), you are already late. Most enterprises need 2–4 years to migrate. Start your inventory this quarter.
03 · NIST PQC standards

We implement what NIST finalized.

Four standardized algorithms. We help you choose correctly — KEMs for key exchange, signatures for identity — and deploy them in hybrid mode alongside your existing PKI. Everything we recommend runs on our own PQC implementation stack: one vetted codebase behind our assessments and deployments.

KEM · FIPS 203

ML-KEM

CRYSTALS-Kyber. Key encapsulation for TLS, VPNs, messaging. Our default: ML-KEM 768 hybrid.

04 · PQC consulting

What QuantX does for you.

A PQC consulting engagement — from discovery to deployed hybrid — typically in 3–6 weeks. Then we stay on as your quantum-safety partner.

🔍

1 · PQC Readiness Assessment

Crypto inventory, TLS fleet scan, certificate & dependency mapping, HNDL exposure scoring, and a prioritized findings report.

🗺️

2 · Migration Roadmap

CNSA 2.0-aligned plan: what to migrate first, hybrid vs. pure-PQC decisions, vendor requirements, timelines, and cost model.

⚙️

3 · Hybrid Deployment

Hands-on implementation: TLS 1.3 + X25519MLKEM768, load balancer / CDN / gateway config, interop testing, rollback-safe rollout.

✅

4 · Validation & Monitoring

Verify with QXScan, add PQC checks to CI/CD, continuous posture dashboards, and re-scan cadence for every release.

🎓

5 · Team Enablement

Engineer & executive workshops: PQC primitives, NIST standards, Mosca planning, and what "quantum-safe" claims actually require.

🧪

6 · Product Partnership

Design partners — starting with QXScan — get early access to new products as they complete vetting, plus co-development input and preferred pricing.

WEEK 1

Discover

Automated scans + stakeholder interviews. Crypto inventory of the scanned fleet.

WEEK 2–3

Plan

Risk-ranked roadmap with quick wins and compliance mapping.

WEEK 3–5

Deploy

Hybrid PQC on staging → production with validation gates.

ONGOING

Verify

Continuous scanning, reporting, and product early access.

05 · Trust but verify

Measured security.
Scan your TLS.

QXScan continuously tests your TLS endpoints — external and internal — against PCI-DSS, HIPAA, SOC2, FISMA, and PQC readiness. Every scan produces a structured, versioned result that feeds your SIEM, syslog, dashboards, and CI/CD, so drift shows up the moment it happens, not at the next audit cycle.

One scan. Five standards.

Scheduled fleet scans — external + internal targetsCONTINUOUS

QXScan Enterprise adds fleet management with SIEM, syslog, and metrics integrations — five profiles today (HIPAA, PCI-DSS, SOC 2, FISMA, PQC), 30+ global standards on the way.

QuantX mission

Building PQC products. Consulting funds the mission.

We're a mission-driven team building post-quantum products — starting with QXScan, with more in the pipeline as they complete vetting. Consulting engagements today shape the products we ship next. Design partners welcome.

Not sure what to ask for?

Mention any of these in your message and we'll scope the right engagement:

TLS posture & compliance — continuous monitoring of external and internal endpoints against PCI-DSS, HIPAA, SOC 2, FISMA, and PQC readiness, with results feeding your SIEM.

Private PKI & certificates — NIST-standard, PQC-ready TLS certs on demand for dev teams, without waiting on a public CA.

Quantum-safe connectivity — post-quantum pre-shared keys rotating every two minutes, so captured sessions expire almost immediately.

Edge & reverse proxy — PQC-first proxying with WAF protection from the same layer: one deployment, not two migrations.
