Products / PQC Companies
Post-quantum cryptography companies.
Post-quantum cryptography (PQC) companies help organizations move from quantum-vulnerable encryption (RSA, ECC, Diffie-Hellman) to NIST post-quantum standards such as ML-KEM and ML-DSA. The field splits into three groups: large enterprise and cloud security platforms, specialized PQC and quantum-readiness firms, and hardware chipmakers building quantum-resistant silicon. ArcQubit sits in the specialized group, with QuCode for cryptographic discovery and QuTrust for migration.
The landscape
Three kinds of PQC company.
The market splits into broad security platforms, specialized PQC firms, and quantum-resistant hardware makers. Most organizations use more than one.
Enterprise & cloud security platforms
Broad security vendors adding PQC and quantum-safe features to existing platforms.
IBM, Amazon Web Services, Palo Alto Networks, Keyfactor
Specialized PQC & quantum-readiness firms
Focused vendors whose core product is cryptographic discovery, migration, or quantum-safe libraries. ArcQubit builds here.
ArcQubit, SandboxAQ, PQShield, QuSecure, CryptoNext Security
Quantum-resistant hardware & chipmakers
Hardware security modules, secure elements, and silicon implementing NIST algorithms.
Thales, NXP Semiconductors
Where ArcQubit fits
A specialized PQC company, discovery through migration.
ArcQubit is a post-quantum cryptography company focused on the full arc from finding quantum-vulnerable cryptography to migrating it, run as a continuous program rather than a one-time snapshot.
- QuCode: cryptographic discovery and inventory across five surfaces, Cloud, IT, OT, AI, and blockchains, that reads existing scanner output.
- QuTrust: a full-stack PQC migration platform with AI-assisted risk scoring, mandate mapping, and audit-ready reporting.
- AI & Quantum Consulting: expert-led assessments, migration programs, and executive advisory.
- Veteran-owned and woman-owned (VOSB/WOSB), with an active federal contracting posture.

FAQ
PQC companies, answered.
The PQC field has three groups: enterprise and cloud platforms (IBM, AWS, Palo Alto Networks, Keyfactor), specialized PQC and quantum-readiness firms (ArcQubit, SandboxAQ, PQShield, QuSecure, CryptoNext Security), and quantum-resistant hardware makers (Thales, NXP). The right choice depends on whether you need discovery, migration, libraries, or hardware.
It helps you find quantum-vulnerable cryptography, prioritize it by risk, and migrate to NIST post-quantum standards without redesigning your systems. Some focus on discovery and inventory, some on the migration program, some on cryptographic libraries or hardware. ArcQubit covers discovery (QuCode) and migration (QuTrust).
ArcQubit discovers quantum-vulnerable cryptography across five surfaces (Cloud, IT, OT, AI, and blockchains), not just certificates, and runs the migration as a continuous, audit-ready program rather than a one-time scan. It is veteran-owned and woman-owned (VOSB/WOSB) with a federal contracting posture.
Check that it discovers public-key use beyond certificates, migrates toward finalized NIST standards (ML-KEM, ML-DSA, SLH-DSA), supports crypto agility, produces audit-ready evidence, runs as a multi-year program, and keeps your evidence portable in open formats.
