Classify government, public-sector, and civic-service domains with precision, and surface impersonation risk.
In filtering deployments this is a near-universal allow-listed category — citizens and employees need reliable access to public services.
Government domains are identified through official TLD signals (.gov, .mil, and national government TLDs), agency-infrastructure patterns, civic-service and benefits-portal structures, and official-publication markup.
Because government brands are frequently impersonated for fraud, classification runs alongside lookalike detection that flags domains mimicking official agencies.
For public-sector deployments in particular, accurate government classification serves two purposes: keeping legitimate civic services reliably accessible under strict filtering, and flagging impersonation domains that spoof agencies to defraud citizens.
Both are essential to a policy that supports access to public services while protecting users from government-themed scams.
The category further separates emergency and public-safety alerts, procurement and open-data portals, and inter-governmental organizations, reflecting the breadth of public-sector web operations.
This depth ensures that critical citizen-facing services — an emergency-alert site during a disaster, a benefits portal at enrollment deadlines — are reliably classified and never treated as unknown domains under a default-deny policy.
Official-TLD, infrastructure, and impersonation signals combine for accurate government identification
Government TLDs — .gov, .mil, and national and sub-national government domains — are strong anchors for the category. We validate these signals against agency infrastructure to confirm genuine official domains and support confident allow-listing.
Government portals share hosting environments, content-management patterns, and accessibility-compliance markers characteristic of public-sector web operations. These signals identify agency and department sites beyond TLD alone.
Benefits applications, permit and licensing systems, tax and payment portals, and public-record lookups have recognizable transactional structures that classify civic-service domains and support citizen-access policy.
Government agencies are heavily impersonated for benefits fraud and phishing. We compute similarity scores against official domains to flag lookalikes — for example, fake benefits or tax sites — as an impersonation-risk signal.
Legislative records, regulatory notices, court filings, and official gazettes carry publication markers that confirm authentic government sources and distinguish them from commentary or third-party republishers.
Government sites are added, reorganized, and migrated across administrations, and impersonation domains appear constantly. Continuous crawling keeps the allow-list current and catches newly registered government-themed lookalikes quickly.
Government classification supports allow-listing, public-sector policy, and fraud defense
Government agencies and public institutions run their own filtering under strict acceptable-use and security policy. Classifying government domains supports reliable inter-agency access while the broader policy remains in force, with audit trails for oversight.
Libraries, schools, and public-access networks must keep civic services reachable so citizens can apply for benefits, file taxes, and access public records. Government classification anchors an allow-list that keeps these services available under filtering.
Government-themed phishing — fake benefits, tax, and immigration sites — targets citizens constantly. Feeding impersonation signals into secure gateways and email defenses helps intercept these scams before users reach them.
Schools keep government and civic resources accessible for research and civics education while filtering harmful content. Government classification ensures official resources are reliably reachable for coursework across student and staff networks.
Coverage and accuracy metrics for the government category
Government classification serves two goals at once.
Citizens and public employees need dependable access to official services, so the category must be a reliable allow-list.
At the same time, government brands are among the most impersonated online, so the same classification must help distinguish genuine agencies from spoofing domains.
We anchor positive classification in official TLD and agency-infrastructure signals that are hard to fake, then run similarity analysis against official domains to flag lookalikes. A real benefits portal is allow-listed; a freshly registered domain mimicking that portal on throwaway hosting is flagged as impersonation risk.
For public-sector deployments and public-access networks, this dual capability is essential. It keeps legitimate civic services reachable even under strict filtering, while feeding fraud-defense signals to the gateways and email systems that protect citizens from government-themed scams.
Deploy government allow-listing and impersonation signals across your stack
Government integration combines dependable allow-listing with fraud defense. Our API returns the government category, a sub-category (national, state or local, agency, civic service, courts, public health), a confidence score, and impersonation-risk indicators, so official services are allow-listed while lookalikes are flagged.

Common questions about the government category
Almost always. Citizens and public employees need reliable access to official services, so government is a near-universal allow-list. The added value is impersonation detection that flags domains spoofing official agencies.
Government brands are heavily impersonated for benefits, tax, and immigration scams. Classification runs alongside lookalike detection, so domains mimicking official agencies are flagged with an impersonation signal your gateways and email defenses can act on.
The category breaks down into national government, state or local government, agency and department portals, civic and benefits services, courts and legislative bodies, and public health and safety, so policy can target each independently.
Reputation is refreshed on a 15-minute cycle with continuous re-scanning. Because government-themed phishing domains are often used within days of registration, rapid refresh is essential to flag them while they are still active.
