CronLab Web Filter is a web and WiFi content filtering service designed primarily for connected device manufacturers such as tablet, phone, router, and WiFi hotspot producers. The service filters URLs and blocks access to content based on categories selected by the operator or end user. Core functionality includes: - URL categorization across a database of 36 billion URLs, organized into 200+ categories - Blocking of adult content, malware, phishing URLs, viruses, and ransomware - Real-time threat detection and zero-hour threat notifications - AI-powered phishing prevention - Bandwidth optimization by restricting access to high-bandwidth sites (e.g., streaming services) - Web Usage Insights: a reporting and analytics dashboard that tracks website visits, frequency, and timing on a given network or device The service is deployed in over 2.5 million devices globally and is used across consumer, public transport, and enterprise contexts. Operators can configure filtering levels and select URL categories to block. The solution supports BYOD environments and public WiFi deployments. CronLab holds the Friendly WiFi certification, an industry standard requiring public WiFi to meet minimum safe filtering requirements, including blocking pornographic and child sexual abuse content. Known deployments include Kurio (children's tablets, 2 million+ devices) and Icomera (public transport connectivity, 1,000+ systems on buses and trains).
