Web Filtering Database — 100 Million Domains Categorized for Filtering

Next-Gen Firewalls

Next-Generation Firewalls depend on accurate domain categorization to enforce granular security policies at the network perimeter. Our offline database allows NGFW vendors to embed a complete 59-category taxonomy directly into their appliance firmware, eliminating external API dependencies.

Firewall administrators can create policy rules that block or allow traffic based on content categories such as gambling, social media, or adult content. The database operates at wire speed because lookups happen locally against a preloaded dataset. Deep packet inspection engines can combine our category data with application signatures for layered enforcement. Security teams gain visibility into which content categories are generating the most traffic across their network. With monthly updates, the category database stays current without requiring constant internet connectivity. Organizations in regulated industries benefit from deterministic, auditable filtering that does not rely on cloud-based classification services.

DNS-Layer Filtering

DNS resolvers are the first checkpoint for every internet connection, making them the ideal enforcement point for content filtering at scale. Our database integrates directly into recursive resolvers and DNS security gateways, enabling category-based blocking at line rate without adding latency.

Service providers can intercept DNS queries and check the requested domain against the local category database in microseconds. Blocked categories return an NXDOMAIN or redirect to a block page, preventing the connection before any content is downloaded. DNS-layer filtering protects every device on the network without requiring endpoint agents or proxy configurations. The 100-million-domain database provides comprehensive coverage that catches newly registered domains through monthly refreshes. Resolver operators can implement tiered filtering profiles for different network segments or subscriber groups. Integration is straightforward with standard RPZ (Response Policy Zone) feeds generated from our category data. This approach scales from small office networks to carrier-grade deployments serving millions of subscribers.

Parental Control Apps

Parental control applications need a reliable, offline-capable content classification database to protect children across all browsing contexts, including when internet connectivity is limited. Our database ships with the application itself, ensuring consistent protection everywhere.

App developers can preload the entire category database onto the device during installation, enabling immediate protection without cloud roundtrips. Parents configure which of the 59 categories are accessible for each child based on age-appropriate profiles. The database classifies domains that children encounter on social media, search results, and shared links in real time. Categories like adult content, gambling, weapons, and drugs are blocked deterministically with no risk of cloud service downtime. Screen time analytics powered by our categories show parents exactly which content types their children are engaging with most. The compact database format minimizes storage footprint on mobile devices while maintaining full classification coverage. Monthly updates ensure new domains are captured without requiring manual intervention from parents.

School & CIPA Filtering

Educational institutions in the United States must comply with the Children's Internet Protection Act (CIPA) to receive E-Rate funding, requiring technology that blocks access to harmful online content. Our database provides the classification backbone that makes CIPA compliance straightforward to implement and audit.

School IT administrators deploy the database on-premise to filter traffic across campus networks, Chromebook fleets, and one-to-one device programs. The 59-category taxonomy maps directly to CIPA requirements including visual obscenity, child exploitation, and harmful-to-minors content categories. Teachers and staff can operate under different filtering profiles than students, allowing access to educational resources that may be restricted for younger users. The offline database ensures filtering continues to function during internet outages, protecting students even when cloud services are unreachable. Audit logs generated from category lookups provide the documentation schools need for E-Rate compliance reviews. Library systems integrate the same database to provide age-appropriate filtering on public-access terminals. District-wide deployments scale from a single school to thousands of sites using centralized database distribution.

Schools and libraries use our database for education web filtering across 100 million classified domains, K-12 content filtering for school districts, and CIPA compliant filtering to maintain E-Rate eligibility.

SOC analysts can automatically tag incoming alerts with category labels, enabling priority-based triage where domains categorized as technology or business receive different handling than those in gambling or adult categories. Threat intelligence platforms enrich domain IOCs with our 59-category taxonomy before distributing them to downstream security tools. The local database enables high-throughput enrichment of bulk indicator feeds without API rate limits or per-query costs. Historical analysis of category distributions across threat campaigns reveals patterns in adversary infrastructure preferences. Automated playbooks use category data to make blocking decisions, escalating only when indicators fall into unexpected categories. The database helps identify domain generation algorithm outputs by flagging newly categorized domains that lack established category histories. Integration with SOAR platforms enables category-aware orchestration workflows that reduce mean time to respond.

Corporate Acceptable-Use

Enterprises enforce acceptable use policies to maintain workforce productivity, reduce legal liability, and protect corporate networks from threats that enter through unrestricted web browsing. Our database provides the classification engine that powers these policies across organizations of all sizes.

IT departments configure category-based rules that block gambling, gaming, streaming, and social media during business hours while allowing access during breaks. The 59-category taxonomy provides granular control so that blocking entertainment does not inadvertently restrict business-relevant sites. Human resources teams rely on category-based browsing reports to identify policy violations without invasive per-URL monitoring of individual employees. The database supports differentiated policies across departments, allowing marketing teams access to social media while restricting it for other business units. Remote workers receive the same policy enforcement through VPN-integrated filtering powered by the local database. Bandwidth-intensive categories like streaming and file sharing can be throttled rather than blocked entirely, balancing productivity with employee satisfaction. Category-based logging provides the audit trail enterprises need for regulatory compliance and internal investigations.
