Government & Public Sector Cybersecurity Market

The government & public sector cybersecurity market is expected to grow from USD 84.99 billion in 2026 to USD 142.93 billion by 2031, at a CAGR of 11.0% during the forecast period. This growth is driven by national cybersecurity strategies and stricter regulatory mandates focused on safeguarding critical infrastructure and government digital assets. Public-private coordination is also becoming more organized to enhance threat preparedness and response. 

Countries such as Australia, the UAE, the UK, India, and the US are enhancing cyber laws, task forces, and oversight frameworks. These initiatives aim to protect government networks and boost cyber readiness across public agencies, driving ongoing demand for cybersecurity solutions and services.

Market Ranking:

In the government & public sector cybersecurity market, competition is dominated by large platform providers, supported by specialized vendors that deliver mission-critical protection for national infrastructure and public services. Microsoft, Leidos, Booz Allen Hamilton, CACI, Accenture, Palo Alto Networks, Cisco, and IBM maintain strong positions due to their mature zero-trust architectures, public sector cloud compliance, and deep integration with federal and civilian agency requirements. These vendors are advancing government modernization through the adoption of secure cloud solutions, identity-based controls, and artificial intelligence-driven threat detection.

Vendor endpoint and threat prevention capabilities are strengthened by companies such as CrowdStrike and Check Point, which assist defense, law enforcement, and government agencies through continuous monitoring and quick incident response systems. Meanwhile, CyberArk and Tenable play key roles in privileged access management and exposure control, highlighting the growing regulatory oversight in the public sector.

Across operational technology-driven critical infrastructure, Honeywell, Dragos, and Claroty focus on securing energy, transportation, and smart city systems against growing geopolitical cyber threats. Threat intelligence and investigation specialists such as Recorded Future and Magnet Forensics are expanding support for national security and law enforcement efforts.

At the same time, providers such as Forescout, Vectra AI, Heimdal Security, and Cydome focus on device visibility, AI-driven detection, resilience in the public sector, and maritime cybersecurity compliance. As agencies adopt zero-trust security more widely, increase cybersecurity investments, and boost cross-border cooperation, competitive pressure grows. This climate pushes vendors to improve government-grade certifications, unify their platforms, and create service models tailored to the needs of the public sector.
