Faultless and Zero-Delay Scan Structure

Zyxel Web Filtering uses hybrid approaches including local cached database and cloud optimized URL database, improving performance and accuracy.

Updated cloud database scan engine:
Combining a filtering structure with a cloud service to ensure zero-delay category detection, Zyxel URL detection provides instant coverage for sites. If a URL is not found in the locally cached database, the querying process will redirect to the security cloud database for URL mapping. The global security cloud database remains up-to-date by processing over 17 billion transactions a day from over 600 million users from 200 countries.

Faultless and zero-delay scan structure

Ultra-low latency via locally cached database scan engine:
The locally cached engine automatically adjusts entries according to the needs of each deployment by quickly learning the browsing habits of users. This is the heart of Zyxel’s Content Filtering, providing high-performance web content scanning and detection.

DNS Content Filter Fills in the Blind Spot

A newly added DNS content filter offers a better approach to inspect web access, particularly when the TLS1.3 website is deploying ESNI (Encrypted Server Name Indication) where the traditional URL filtering fails to identify the destination domain.
