Market Definition
The government & public sector cybersecurity market refers to the part of the global cybersecurity industry that includes solutions and services used to protect digital infrastructure, systems, networks, and data for government agencies and publicly owned or government-controlled institutions.
This includes cybersecurity spending by federal, state, and local government entities, such as ministries, departments, agencies, and defense and intelligence organizations responsible for national security and cyber operations.
Additionally, the market includes cybersecurity investments made by public sector institutions across key industry sectors, such as banking (including state-owned banks and central banks), healthcare (public hospitals and national health systems), energy and utilities (state-owned utilities and grid operators), transportation (railways, ports, airports, and public transit systems), telecommunications (state-owned providers and national network infrastructure), and public education institutions, as well as government-owned or managed critical infrastructure assets.
The market is structured into two primary components:
(1) Core Government Entities – Comprising ministries, departments, and agencies across all levels of government, including defense and intelligence bodies
(2) Public Sector Institutions – Comprising operational and service-delivery organizations that are publicly owned or controlled, such as public hospitals, state-owned banks, utilities, transport authorities, and similar entities, even if administratively governed by government bodies
The market covers a wide range of cybersecurity technologies and services, such as network security, endpoint security, identity and access management (IAM), data security, SIEM, cloud security, application security, and managed security services. It is measured by the revenue generated by cybersecurity vendors from public sector end users. The total market size is calculated as 100% of cybersecurity spending by core government agencies, plus a proportional share of cybersecurity expenses within other industry sectors that are owned or controlled by the government.
The scope excludes cybersecurity spending by private sector organizations, including privately owned enterprises operating in regulated industries, as well as public-private partnership (PPP) entities where majority ownership and operational control do not lie with government authorities.
