Web Filtering / Parental Controls

We Categorize Web Content Using Topic-based, Objectionable, and Malicious Classifications for Powering Leading Safety and Security Solutions

zveloDB for Web Filtering

zveloDB provides market-leading accuracy, coverage, and malicious website detection with flexible deployment options and exclusive “category mapping” technology. zveloBD enables web filtering vendors to exactly mirror the category sets familiar to system administrators and end users for policies and reporting. If you are a DNS, UTM, SaaS, or other vendor and need a premium URL database for the SOHO, SMB, Enterprise, or Gov/Ed market, zveloDB is the premier choice.


We use AI/machine learning combined with human quality assurance to maintain over 99% accuracy for categorizing web content into topic-based, objectionable, and malicious categories.


Over 99.9% coverage of the active web traffic, incorporating URLs that have been visited by our global network of 500 million users across Information Security, IoT Security, and Ad Tech markets.

Language Support

The market’s best language support by country, covering over 200 languages, using human-supervised machine learning systems. See our Language Support Map.

Fast Performance

Local lookups in 5 microseconds or 200,000 queries per second per instance using the zveloDB SDK, supplemented by cloud updates for uncategorized URLs. Alternatively, take complete control by directly ingesting all categorized URLs into your systems with a raw data stream.

Malicious Detection

Interrogate threats at the URL and IP level and identify malicious activities such as malware, phishing, fraud, and spyware. zvelo employs a crowd-sourced approach for obtaining a constant stream of URLs to analyze by combining static analysis, behavioral analysis, 3rd party industry feeds, and human-supervised machine learning to deliver the most extensive malicious site detection.

View our Global Cyber Threat Map which shows a sampling of currently identified malicious threats with the choice to toggle between recent detections and a density heatmap of malicious detections.

Objectionable Content

This versatile set of categories can be used in a wide variety of cultural settings. Identify URLs and for parental controls applications to block inappropriate or objectionable categories consisting of various levels of severity including porn, hate speech, violence, etc.
