정부 및 공공 부문 사이버 보안 : 시장 점유율 분석, 업계 동향과 통계, 성장 예측(2026-2031년)

The Government And Public Sector Cybersecurity Market was valued at USD 75.14 billion in 2025 and estimated to grow from USD 84.61 billion in 2026 to reach USD 153.35 billion by 2031, at a CAGR of 12.62% during the forecast period (2026-2031).

Escalating state-sponsored attacks, fast-tracking of zero-trust mandates, and quantum-resistant encryption projects are reshaping procurement priorities across every tier of government. NATO's pledge to spend 1.5% of GDP on cyber resilience is diverting defence resources toward new threat-intelligence platforms, while federal budgets in the United States, the European Union, and key Asia-Pacific economies are earmarking multi-year allocations that favour end-to-end managed security services. Spending is shifting from reactive perimeter protection to proactive detection powered by artificial intelligence, augmented by workforce outsourcing to offset talent shortages. As a result, the government and public sector cybersecurity market is experiencing broader vendor consolidation, deeper public-private partnerships, and longer contract tenures anchored in performance-based service-level agreements.

Global Government And Public Sector Cybersecurity Market Trends and Insights

Escalating State-Sponsored Cyber-Attacks on Critical Public Infrastructure

State-linked groups such as Salt Typhoon have breached federal networks and telecom infrastructure, demonstrating how adversaries leverage supply-chain compromises to gain persistent access to multiple government domains. Security teams now prioritise continuous monitoring, threat hunting, and forensic readiness, replacing periodic "point-in-time" scans. High-profile water-utility disruptions in 2024 revealed that operational technology environments can be weaponised to cause real-world service outages, prompting agencies to adopt cross-domain security architectures. Budget allocations, therefore, increasingly favour threat-intelligence feeds, endpoint detection, and 24 X 7 incident-response retainers. The cumulative effect is sustained demand for integrated solutions that shorten detection-to-containment cycles across federal, state, and local layers.

Government Zero-Trust Funding Mandates and Compliance Deadlines

The United States Defense Information Systems Agency is rolling out a zero-trust framework that requires identity verification, device hygiene, and micro-segmentation for every transaction across Department of Defense networks. Failure to meet timeline targets risks budget forfeiture, so agencies accelerate multi-factor authentication and continuous diagnostics deployments. State and local bodies align with federal standards to unlock matching funds, evident in California's USD 22.6 million grant pool that prioritises zero-trust implementations. Vendors offering consolidated platforms spanning identity, endpoint, and cloud workloads gain a competitive advantage in crowded tenders, while integrators differentiate through reference architectures that map legacy assets to zero-trust maturity models. As deadlines converge in 2026, procurement pipelines are filling rapidly with multi-year, performance-based contracts.

Legacy System Integration and Technical Debt

Decades of incremental upgrades have left agencies with siloed mainframes, proprietary protocols, and undocumented interfaces that complicate modernisation projects. Implementing zero-trust across such heterogeneous environments often demands costly data migrations and parallel operations, inflating budgets beyond initial estimates. In Michigan, ransomware actors exploited outdated authentication controls in municipal servers, paralysing essential operations and illustrating the direct link between technical debt and operational risk. Federal audits estimate individual legacy-system overhauls can cost more than USD 100 million, forcing agencies to stage rollouts and rely on compensating controls that add further complexity. These constraints slow the adoption of advanced security frameworks and dilute the immediate impact on threat-mitigation metrics.

Segment Analysis

Network Security recorded USD 21.27 billion in 2025 and defended a 28.31% government and public sector cybersecurity market share on the strength of entrenched perimeter firewalls and intrusion-prevention systems that remain baseline procurement line items. Budget line continuity reflects audit mandates that still prioritise perimeter visibility despite known limitations against lateral movement. Yet Cloud Security generated only USD 13.34 billion but is forecast to grow faster at a 13.05% CAGR through 2031 as agencies transition citizen services into FedRAMP and ENISA-certified hosting. Identity and Access Management is also scaling as zero-trust checkpoints redistribute security emphasis toward user verification and continuous authentication. Rising endpoint investments underpin secure telework policies, while application-layer testing enjoys uplift from large-scale digital-service overhauls.

By 2031, Cloud Security is projected to claim a material share of the government and public sector cybersecurity market size, illustrating how hybrid architectures elevate demand for data-centric controls alongside flexible policy orchestration. Encryption and data-security upgrades accelerate as post-quantum migration deadlines approach, influencing procurement specifications to demand NIST-validated algorithms. Vendors are bundling key management as-a-service with analytics to simplify deployment across multi-cloud environments. In parallel, application-security gateways incorporate API posture management to police interactions with third-party contractors and software supply-chain dependencies. Combined, these shifts underscore a transition from single-point products to layered, interoperable security suites that map neatly to evolving architecture roadmaps.

On-premises systems retained USD 39.18 billion in revenue and 52.15% government and public sector cybersecurity market share during 2025. Sensitive workloads such as defence command-and-control and citizen identity repositories remain anchored in agency-controlled data centres, but the narrative is changing as risk-based classification models free less critical data for cloud processing. Cloud deployments, valued at USD 19.68 billion, are advancing at a 12.78% CAGR, fuelled by consumption-based pricing and the operational flexibility needed for elastic service demand during emergencies. Hybrid strategies bridge compliance with efficiency: agencies adopt containerised micro-services for new applications while gradually retiring monoliths.

As cloud confidence builds, hybrid architectures are forecast to add USD 16.1 billion to the government and public sector cybersecurity market size by 2031, requiring unified policy engines that span identity, data, and network controls. Secure access service edge solutions emerge as the connective tissue, routing traffic through inspection nodes regardless of hosting location. Vendors differentiate by offering pre-packaged reference designs that accelerate accreditation under FedRAMP Moderate and NIS2 compliance tracks. Meanwhile, funding frameworks now earmark modernisation grants specifically for orchestration platforms that normalise compliance reporting across mixed environments, signalling that hybrid will dominate new awards through the forecast window.
