The rapid growth of IoT ecosystems, expected to surpass 40 billion connected devices by 2030, combined with the widespread adoption of cloud computing in enterprises, is fueling the need for quantum-resistant encryption. As organizations increasingly rely on cloud services, SaaS applications, and hybrid infrastructures, PQC ensures secure communication, protects sensitive data, and safeguards smart factories, healthcare systems, and critical infrastructure against emerging quantum threats.
Based on the solution segment, the quantum-resistant encryption segment will account for the highest growth rate during the forecast period.
Quantum-resistant encryption solutions represent the fastest-growing segment in the PQC market because they directly address the vulnerability of widely used public key cryptosystems, such as RSA and ECC, to Shor’s algorithm on quantum computers. These solutions rely on advanced mathematical constructs, including lattice-based schemes such as CRYSTALS Kyber, code-based cryptography like Classic McEliece, and multivariate polynomial approaches, which are believed to resist both classical and quantum attacks. A key example is Google’s experiment with hybrid post-quantum TLS in Chrome, where lattice-based algorithms were integrated into HTTPS connections to evaluate real-world performance and security implications without disrupting user experience. Similarly, Cloudflare and AWS have tested quantum-safe key exchange mechanisms in their infrastructures to prepare for long-term confidentiality of sensitive data. These efforts demonstrate how industries handling critical information, such as banking, defense, and healthcare, pilot these solutions to secure communications, digital signatures, and stored records that must remain confidential for decades. The combination of practical deployment pilots, ongoing NIST standardization, and rising enterprise demand positions quantum-resistant encryption as the most technically advanced and commercially promising pathway for building quantum-safe security architectures.
By vertical, the BFSI segment will account for the largest market share during the forecast period.
PQC is becoming increasingly important in the BFSI sector as financial institutions prepare for the potential threats of quantum computing, which could compromise traditional encryption methods such as RSA and ECC. PQC solutions are critical in safeguarding sensitive financial data, securing online transactions, enabling quantum-resistant digital signatures, and ensuring compliance with emerging regulatory standards. Despite this urgency, a study by the ISB Institute of Data Science revealed that India’s BFSI sector has a relatively low average PQC preparedness score of 2.4 out of 5 among CISOs and CTOs, with over half of professionals anticipating significant quantum-related security threats within the next three years. A notable example is Mastercard’s 2023 pilot of quantum-resistant algorithms in its network to secure transactions against quantum threats. Meanwhile, Visa has collaborated with IBM to test post-quantum digital signatures for payment authentication. Industry reports indicate that more than 50% of European banks have begun conducting cryptographic inventories to assess exposure to quantum vulnerabilities, and global initiatives such as the Financial Services Information Sharing and Analysis Center (FS-ISAC) are running joint testbeds to validate NIST-selected PQC algorithms in financial messaging and SWIFT communications.
By region, Europe will grow at the highest CAGR during the forecast period.
Europe is positioning itself as a frontrunner in transitioning to post-quantum cryptography, supported by strong regulatory alignment and government initiatives. The European Commission issued a Coordinated Implementation Roadmap in 2024, requiring member states to define strategies, milestones, and hybrid deployment plans for PQC across public administrations and critical infrastructures. Germany is advancing PQC through the Federal Office for Information Security (BSI) and Fraunhofer projects, such as QuantumRISC and Quant-ID, with a focus on hybrid cryptography, automotive security, and quantum-safe identities in banking and public services. The UK’s National Cyber Security Centre (NCSC) has set phased deadlines, calling on critical national infrastructure operators to map cryptographic dependencies by 2028 and complete PQC migration by 2035. France’s cybersecurity agency ANSSI promotes PQC readiness for government and enterprise applications, while Spain’s CCN drives adoption through pilot deployments aligned with international standards. At the EU level, over USD 20.5 million has been allocated to initiatives such as Qu-Pilot, which creates cross-country testbeds for PQC and quantum-safe systems. Collectively, these developments highlight Europe’s emphasis on hybrid implementations, regulatory-backed adoption, and cross-border collaboration to prepare for quantum-enabled threats.

Unique Features in the Post-quantum Cryptography Market
Market acceleration and funding focus: The PQC market is growing rapidly as organizations and governments accelerate spending on quantum-safe products, driving large investments into vendors, startups, and integration services to replace or harden existing public-key systems.
Standards and regulatory pressure: A defining feature is active standardization — notably NIST’s multi-year PQC standardization program and published PQC standards — which is shifting vendor roadmaps and forcing adoption timelines for enterprises and cloud providers. Standards activity is the single biggest coordinating force in the market.
Algorithm diversity and specialization: Unlike legacy crypto (RSA/ECC), the PQC market contains multiple algorithm families (lattice-based, code-based, hash-based, multivariate, etc.), and vendors position offerings around specific algorithm tradeoffs — performance, key sizes, and security proofs — creating product differentiation.
Crypto-agility and migration services: A unique commercial niche is migration/tooling — “crypto-agility” platforms, hybrid deployments (classical + PQC), key-management upgrades, and migration consulting are major revenue drivers because replacing crypto in large systems requires orchestration, testing, and staged rollouts.
Major Highlights of the Post-quantum Cryptography Market
The global market is witnessing a strong transition toward quantum-resistant cryptographic solutions as industries prepare for the potential threat posed by quantum computers. Organizations across sectors such as finance, defense, telecommunications, and healthcare are proactively investing in PQC to secure long-term data confidentiality and integrity.
Governments and regulatory bodies are playing a pivotal role in driving PQC adoption. Initiatives like the U.S. National Institute of Standards and Technology (NIST) PQC standardization project and the European Telecommunications Standards Institute (ETSI) guidelines have accelerated the creation of global standards and compliance frameworks.
Leading cloud providers, network vendors, and cybersecurity firms are embedding PQC algorithms into their existing infrastructure. PQC-enabled TLS protocols, VPNs, and PKI systems are being tested and deployed to ensure seamless migration to quantum-safe architectures.
A major highlight of the PQC market is the increasing use of hybrid encryption schemes that combine classical and post-quantum algorithms. This hybrid approach allows organizations to achieve backward compatibility while gradually transitioning to quantum-safe systems without disrupting existing workflows.
