PQC Solutions (post-quantum cryptography): The Race is On!

Date: January 9, 2026


Several companies are actively working on post-quantum cryptography (PQC) to prepare for the future threat posed by quantum computing. Major technology and cybersecurity firms leading this effort include Google, IBM Research, Microsoft Research, Intel, AWS, Cisco, and Thales/Gemalto.  These companies are developing quantum-resistant algorithms, integrating PQC into their services and products, and contributing to standardization efforts.

 

Other key players in the PQC market include NXP Semiconductor, Palo Alto Networks, IDEMIA, DigiCert, and Patero, which collectively account for a significant portion of the market share.


NXP specializes in secure connectivity and microcontrollers, while Palo Alto Networks focuses on enterprise-grade security solutions.  IDEMIA and Thales are prominent in digital security, particularly for government and corporate clients.

 

Specialized PQC vendors are also making significant contributions. PQShield provides cryptographic IP for hardware and embedded systems, with a focus on silicon-level security.


QuSecure offers end-to-end PQC orchestration for critical infrastructure and government systems.  ExeQuantum delivers PQC as a Service (PQCaaS), enabling practical migration for enterprises and governments.  QryptoCyber specializes in cryptographic inventory and risk analysis, helping organizations assess and manage quantum vulnerabilities.

 

Other notable companies include ISARA, which focuses on crypto-agility and PKI migration, Quantropi, which offers symmetric PQC for messaging and data at rest  , and SandboxAQ, which uses AI to discover cryptographic vulnerabilities.  Quantum Xchange provides the Phio Trusted Xchange platform, integrating PQC for secure communications.  Rambus and Keyfactor are also active in developing secure hardware and key management solutions.

 

Additionally, startups like Crypto4A, Qrypt, and Quranium are innovating in hardware security modules, quantum entropy, and quantum-native blockchain infrastructure, respectively. The PQC market is also seeing collaboration through initiatives like the Post-Quantum Cryptography Alliance, launched by the Linux Foundation with AWS, Cisco, Google, IBM, and others.  These collective efforts reflect a global push to ensure data security in the post-quantum era.

10 Post-Quantum Cryptography (PQC) Vendors Shaping the Quantum-Safe Future



As the global tech community braces for the post-quantum era, encryption as we know it is about to be rewritten. RSA, ECC, and classical encryption protocols are increasingly vulnerable to the power of quantum computing. In response, a new breed of cybersecurity innovators is leading the charge toward post-quantum cryptography (PQC) — and they’re not just preparing for the future, they’re building it.


Here are ten of the most important PQC vendors to watch in 2025. Some are deeply technical, some are platform-native, and others are making enterprise adoption accessible for the real world.


1. PQShield

📍UK | Focus: Hardware, Messaging, Standards

PQShield is one of the few vendors with a seat at the NIST table. Their cryptographic IP can be dropped into chips, smartcards, and secure apps, making them a go-to for OEMs and telco-grade security providers. If you want post-quantum security starting at the silicon level, PQShield’s your bet.

Best for: Hardware vendors, IoT devices, embedded systems.


2. QuSecure

📍US | Focus: Orchestration, Federal, Zero Trust

QuSecure’s QuProtect platform enables end-to-end PQC orchestration in live environments. With customers in government and defense, they specialize in seamless crypto agility, TLS upgrades, and full-stack policy management.

Best for: Critical infrastructure, defence, enterprise networks.


3. ExeQuantum

📍Australia | Focus: PQCaaS, Compliance, Broad Integration

ExeQuantum offers PQC as a Service (PQCaaS) with flexible APIs, cloud/on-prem delivery, and TLS wrapping capabilities. Their focus is practical migration — helping organizations of all sizes implement quantum-safe encryption without ripping out existing infrastructure. Known for their “missing puzzle piece” narrative, they provide crypto-agility, QRNG integration, and white-label support.

Best for:Enterprises seeking ISO/GDPR/ISM-aligned PQC, Governments migrating legacy systems, IoT and mobile devices, Construction/logistics platforms, Blockchain/fintech.


4. QryptoCyber

📍US | Focus: Cryptographic Inventory, CBOM, Risk Analysis

QryptoCyber takes a different but critical approach: find and map your current encryption. Their platform scans internal networks, codebases, databases, and assets to create a Cryptographic Bill of Materials (CBOM) — an essential tool for any serious post-quantum migration. They also provide Quantitative Quantum Risk Analysis (QQR) to calculate exposure and remediation paths.

Best for: Enterprises with legacy systems, compliance teams, quantum-readiness assessments.


5. Quranium

📍Singapore, Switzerland, UAE | Focus: Blockchain, DLT, DeQUIP

Quranium is a quantum-native Layer 1 blockchain built from the ground up using post-quantum cryptography. Through its DeQUIP (Decentralized Quantum-Uncrackable Infrastructure Protocol) architecture, it redefines Web3 infrastructure security. From wallets to supply chains, Quranium is setting the bar for post-quantum resilience in decentralised networks.

Best for: RWA tokenisation, DeFi, blockchain identity, secure logistics, payments, and infrastructure.


6. Qrypt

📍US | Focus: Quantum Entropy, Stateless Encryption

Qrypt removes the need for key exchange using quantum entropy. It generates truly random keys distributed to both parties via secure quantum channels, offering a unique angle that goes beyond PQC algorithms.

Best for: Long-term data confidentiality, military-grade systems, zero-key-exchange protocols.


7. Crypto4A

📍Canada | Focus: Hardware Security Modules, Secure Boot

Crypto4A builds cryptographically agile hardware security modules (HSMs) and secure firmware, making it ideal for environments where trust anchors and secure boots matter. With deep government and defense ties, it’s Canada’s stronghold in high-assurance crypto.

Best for: Defence systems, firmware integrity, secure cloud provisioning.


8. ISARA

📍Canada | Focus: Crypto-Agility, PKI Migration

ISARA helps companies transition to PQC without breaking existing PKI stacks. Their hybrid toolkits allow for phased upgrades to crypto infrastructure, making them ideal for large enterprises and OEMs.

Best for: Automotive, telco, public key infrastructure, certificate authorities.


9. Quantropi

📍Canada | Focus: Symmetric PQC, Messaging, Data at Rest

Quantropi offers proprietary symmetric encryption built to be quantum-resistant from first principles. Their TrUE platform supports identity, messaging, and secure storage in distributed environments.
