A subsidy is public financial support that lowers a cost or encourages a specific activity. In security policy, subsidies can take the form of grants, rebates, vouchers, or tax credits for buying safer software, deploying multi-factor authentication, training staff, or hardening critical systems.
Subsidies matter in cyber security because many organizations delay defenses when the upfront cost is high. Public support can speed adoption of basic controls and reduce risk across supply chains, especially for small firms and public institutions. But subsidies also create attack surface: criminals may target application portals, steal identities, submit fake claims, or abuse weak verification to divert funds. Good subsidy design therefore needs strong identity checks, fraud detection, audit logs, and clear eligibility rules. In practice, a subsidy is not just economic support; it is also a security control that must be protected like any other high-value digital service.
