Top Post-Quantum Cryptography Platforms
Most teams discover their cryptography sprawl during an outage or certificate expiry, not from a planned audit. Working across different tech companies, we have seen the same blind spots recur - like TLS 1.3 hybrid handshakes failing after ML-KEM updates, dormant RSA keys hiding in legacy APIs, and compliance teams struggling to build a real Cryptographic Bill of Materials. In August 2024, NIST finalized the first three PQC standards - ML-KEM, ML-DSA, and SLH-DSA - for immediate use, which turned roadmap debates into engineering work overnight (NIST announcement). Our analysis indicates that platforms combining discovery, policy, and change orchestration save the most time during migration.
The post-quantum cryptography market was approximately $2.17 billion in 2026 and is forecast to grow at 37.6 percent CAGR to reach $7.82 billion by 2030, according to Grand View Research.
QuProtect (QuSecure)
A crypto-agility platform that discovers your cryptography, enforces policies, and upgrades algorithms across networks without code changes, per vendor documentation. Recognized by third parties for product leadership and listed on AWS Marketplace.
- Best for: Enterprises and public sector teams that need crypto discovery, policy enforcement, and runtime remediation across heterogeneous networks.
- Key Features:
- Cryptographic discovery and CBOM style reporting, per vendor documentation.
- Runtime remediation and policy-based algorithm rotation without app redeploys, per vendor documentation.
- Compliance reporting mapped to CNSA 2.0 and NIST guidance, per vendor documentation.
- Why we like it: The network overlay model can reduce developer change risk when you must move to ML-KEM and ML-DSA before all apps are ready. It aligns with inventory and migration expectations in federal guidance like NSM-10 and OMB M-23-02.
- Notable Limitations:
- Limited public customer reviews at the time of writing, with only one visible review on G2's QuSecure profile.
- Enterprise pricing tier may be prohibitive for smaller teams.
- As with any in-line remediation, change control and integration testing are still required in regulated networks, a common PQC migration challenge highlighted by Cloudflare's PQC deployment notes.
- Pricing: Available via AWS Marketplace with flexible licensing options (AWS Marketplace). Government procurement routes are also publicly noted via GSA MAS availability in a Business Wire release. Contact vendor for current pricing.
PQC Now Ecosystem
An ecosystem that includes a PQC-enabled browser, wallet, document signing, and PQC certificate issuance, per vendor documentation. Emphasizes ML-DSA certificates and signatures.

- Key Features:
- Chromium-based PQC browser with ML-DSA validation, per vendor documentation.
- Document signing using ML-DSA and wallet integration, per vendor documentation.
- PQC certificate issuance with multiple security levels, per vendor documentation.
- Why we like it: Useful as a sandbox to test pure PQC certs and signature flows while mainstream browsers and CAs standardize hybrid approaches.
- Notable Limitations:
- Browser and WebPKI ecosystem support for pure PQC TLS remains limited, while mainstream browsers have moved to hybrid ML-KEM for key agreement (Google security blog, Chrome 131 ML-KEM; Cloudflare PQC support matrix).
- Very limited third-party adoption signals, for example a small install footprint on the PQC wallet Chrome extension listing at the time of writing (Chrome Web Store listing).
- Limited independent reviews or analyst coverage we could verify.
- Pricing: Pricing is publicly listed on the vendor site for PQC certificates, but not independently verified. Treat as indicative and confirm with sales.

Problems & Solutions
-
Problem: Browser and server friction during PQC rollout. Chrome 131 moved to ML-KEM hybrids, deprecating Kyber hybrids, which can cause handshake mismatches until servers update.
- How tools help: QuProtect's policy-based remediation can standardize cipher negotiation at the network edge, reducing app changes, while PQCrypto's TLS 1.3 libraries help app teams test ML-KEM safely, per vendor documentation. Plan tests against up-to-date client matrices and provider notes like Google's Chrome ML-KEM update.
-
Problem: Agencies must inventory cryptographic systems and plan PQC migration per NSM-10 and OMB M-23-02. The first deadline required inventories by May 4, 2023, then annually through 2035.
- How tools help: Qinsight builds a CBOM and PQC exposure score suitable for audit evidence, then QuProtect or PQCrypto can drive remediation and staged upgrades. See ExecutiveGov's summary of OMB's memo.
-
Problem: PQC for signatures, code, and certificates is arriving in cloud KMS and private CA stacks, but ecosystem compatibility is uneven.
- How tools help: PQC Now's document signing and PQC certificates are useful for controlled pilots. In production PKI, test ML-DSA in your existing KMS flows with AWS KMS ML-DSA support and AWS Private CA PQC certificates, then phase rollout to public endpoints as CA/B Forum guidance evolves (Chrome Root Program update).
-
Problem: Waiting increases risk and cost. Average breach costs hit $4.44 million in 2025 (down from $4.88 million in 2024), and HNDL means long-lived data is at risk today.
- How tools help: Start with discovery and CBOM, then protect high-value data paths with hybrid ML-KEM and ML-DSA signers. See IBM's 2025 Cost of a Data Breach report.
The Bottom Line on Quantum-Safe Platforms
Organizations think they know their cryptography until a real inventory shows how much RSA and ECC still guard critical traffic. Standards are here, with ML-KEM, ML-DSA, and SLH-DSA finalized for use, browser stacks are shifting to hybrid ML-KEM, and cloud KMS and private CAs now offer quantum-safe signatures. From our experience in the startup ecosystem, the fastest wins come from pairing a posture platform for CBOM and reporting with a remediation layer that can enforce ML-KEM and rotate signatures without destabilizing apps. Start there, pilot fast, and expand with clear policy and change control.
