Violence & Graphic Content Filtering

How Violent & Graphic Domains Are Detected

The violence category covers sites whose primary purpose is displaying gratuitous gore, shock imagery, real-world violence, or graphic content intended to disturb. The classification challenge is that violence appears legitimately across news, medical, historical, artistic, and gaming content — so the engine focuses on gratuitous, shock-oriented presentation rather than the mere presence of violent subject matter.

Content analysis uses computer-vision and text models to identify graphic gore, injury, and shock imagery and to weigh how central it is to the page's purpose. A news report depicting conflict, a medical trauma reference, and a shock-gore aggregator can all contain violent imagery, but they differ sharply in framing, surrounding context, and editorial intent — signals the engine is trained to read.

Reputation and infrastructure layers add breadth: shock-content aggregators cluster in identifiable link neighborhoods and ad ecosystems, and continuous re-scanning keeps the category current as sites appear and shift. The result is precise enough to deploy in schools and workplaces without blocking legitimate news, history, or medical resources.

Deployment Options

DNS-based filtering provides the broadest coverage with minimal setup: point resolvers at the API or load the RPZ feed to protect every device, capturing requests from all applications, not just browsers.

Web-proxy integration through ICAP or ECAP adds inline inspection for HTTPS traffic under SSL inspection, catching graphic content hosted on shared platforms whose parent domain is not itself classified.

Developers building safeguarding tools, moderation pipelines, or parental controls can use the real-time API for sub-10ms lookups, with batch endpoints for pre-loading data at scale.

• DNS RPZ feeds updated every 15 minutes
• ICAP/ECAP support for web proxy integration
• REST API with sub-10ms response times
• SDKs for Python, Node.js, Go, Java, and C#
