Zscaler

Zscaler is a cloud-native security platform providing secure internet access (ZIA), private application access (ZPA), and digital experience monitoring as part of a comprehensive SASE/SSE architecture. Operating the world's largest inline security cloud, it inspects all traffic including encrypted connections without requiring on-premises hardware. 

Zscaler generates detailed logs for every web transaction, DNS query, firewall event, DLP match, and CASB action processed through its cloud. These logs capture user identity, application, URL category, threat verdict, and data classification for all internet-bound and private application traffic, providing security teams with comprehensive visibility into user activities and threats regardless of user location.
