Quantum Cybersecurity Market Size, Trends, and Forecast 2027-2037 | Global Deadlines Drive Investment in Post-Quantum Migration and Managed Security

Dublin, Nov. 02, 2026 (GLOBE NEWSWIRE) -- "The Quantum Cybersecurity Market 2027-2037" has been added to ResearchAndMarkets.com's offering.

The report provides a comprehensive analysis of the global quantum cybersecurity market, with forecasts from 2027 to 2037 and market intelligence current to October 2026. It examines how binding post-quantum migration deadlines across the US, Europe and Asia-Pacific are accelerating funded security programmes and influencing investment in quantum-safe technologies, infrastructure and services.

Market coverage is structured around six core segments: post-quantum cryptography software, PQC hardware, cryptographic discovery and crypto-agility, quantum key distribution (QKD), quantum random number generation (QRNG), and migration and managed services. The analysis evaluates the quantum threat and Q-Day timeline alongside regulation, technical standards, network infrastructure, end-use demand, regional developments and the competitive landscape.

Key areas covered in the report include:

• Market outlook and strategic analysis: Executive findings address the quantum threat, the impact of legally mandated deadlines in 2026, ten-year total addressable market projections by cryptographic approach, segment performance, end-use opportunities, market drivers, adoption barriers and strategic recommendations.
• Quantum cybersecurity technologies: Coverage includes classical public-key cryptography vulnerabilities, Shor's and Grover's algorithms, hybrid security approaches, the quantum-safe security stack and the evolving technology market map.
• Quantum threat assessment: The report assesses cryptographically relevant quantum computer development, declining resource estimates, hardware roadmaps, Q-Day projections, harvest-now-decrypt-later risks, Mosca's inequality, blockchain exposure and geopolitical considerations.
• Policy, regulation and standards: Analysis encompasses US federal civilian and national-security systems, NIST standards, the October 2026 GAO audit, financial-sector initiatives and regulatory developments across the EU, UK, the Americas and Asia-Pacific. A global mandate and deadline matrix highlights regional requirements, standards bodies and differing policy positions on QKD.
• Post-quantum cryptography: Technical coverage includes algorithm families, NIST standards, performance and key-size implications, hybrid key exchange, protocol integration, quantum-safe PKI, code signing, embedded and IoT environments, side-channel security and open-source libraries.
• Security infrastructure and enabling technologies: Dedicated analysis examines cryptographic discovery, inventory management, crypto-agility, HSMs, secure elements, silicon, QKD and QRNG. Each technology area includes supplier analysis and market forecasts for 2027-2037.
• Quantum-safe network migration: The report evaluates communications infrastructure, the installed network base, technology refresh cycles, migration requirements and the growth of managed quantum-safe security services.

The quantum cybersecurity market forecasts are segmented by technology, cryptographic approach, end-user sector and region. Scenario-based projections provide insight into adoption rates, procurement priorities and potential revenue opportunities across government and defence, BFSI, telecommunications, cloud services, energy and utilities, healthcare, automotive and IoT, and digital assets.

Competitive intelligence includes profiles of 72 companies active across post-quantum cryptography, QKD, QRNG, hardware security, migration services and related cybersecurity markets. The report also reviews investment activity, M&A, technology readiness levels, SWOT factors and Porter's five forces to assess market positioning and commercial potential.

Regional analysis identifies how national security requirements, compliance schedules, infrastructure maturity and public-sector procurement are shaping quantum cybersecurity adoption. By combining policy tracking, technology assessment, company profiles and ten-year market forecasts, the report supports cybersecurity vendors, investors, government agencies, network operators and enterprise decision-makers planning for post-quantum migration.
