Abstracts

Quantum cybersecurity covers the technologies and services that protect data, communications and digital identities against attack by cryptographically relevant quantum computers (CRQCs). A machine of this kind running Shor’s algorithm would break the RSA and elliptic-curve public-key cryptography that secures almost every digital transaction, network session, software update and identity system in use today. The threat is already live, because adversaries can harvest encrypted traffic now and decrypt it once quantum capability arrives. Data with a confidentiality life of ten years or more is therefore exposed today.

In 2026 the market moved from preparation to compliance. NIST finalised the post-quantum standards ML-KEM, ML-DSA and SLH-DSA in 2024, and FN-DSA and HQC are close behind. The June 2026 US executive order (EO 14412) and OMB memorandum M-26-15 require quantum-resistant key establishment for high-value federal systems by the end of 2030 and signatures by 2031. A FAR rule is set to extend the 2030 deadline to federal contractors. CNSA 2.0 requires new US national security system acquisitions to be quantum-safe from January 2027. The EU coordinated roadmap, the UK NCSC timeline, Germany’s BSI, France’s ANSSI, India, Australia and the G7 financial sector have set comparable milestones. Readiness lags far behind: in October 2026 the US GAO found that only one of 24 major federal agencies had completed its cryptographic inventory.

The market spans six areas:

• post-quantum cryptography (PQC) software, libraries and IP;
• PQC-enabled hardware such as HSMs, secure elements and silicon;
• cryptographic discovery and crypto-agility platforms;
• quantum key distribution (QKD);
• quantum random number generators (QRNG);
• quantum-safe migration and managed services.

The Global Quantum Cybersecurity Market 2027–2037 is an in-depth analysis of the market for quantum-safe security products and services, with forecasts from 2027 to 2037 and information current to October 2026. It sets out how binding deadlines in the United States, Europe and Asia-Pacific are turning post-quantum migration into funded programmes. It sizes the opportunity for vendors, operators, integrators and investors.

The report provides ten-year forecasts in two ways. The first is by product segment: PQC software and IP, PQC-enabled hardware, discovery and crypto-agility platforms, QKD and QRNG. The second is a total addressable market for products and migration services split by cryptographic approach: lattice-based PQC, hash-based signatures, code-based and other PQC, symmetric and key-distribution architectures, QKD and QRNG. Forecasts are also broken down by end-use market, region, device type, QKD system type and service type, with three growth scenarios. The report also estimates the installed base of routers, switches, firewalls and SD-WAN by major vendor, and how quickly it becomes PQC-capable through hardware refresh. A comprehensive company profiles section covers 72 companies.
