Endpoint agent does not detect file upload to chatbase.co over chrome browser.

Products

• Data Loss Prevention Enterprise Suite

Issue/Introduction

File uploads to chatbase.co are not detected by endpoint agent 

Cause

Website behavior.

Because of the design of these websites, DLP agent's OnChange event handler does not fire and so this will also be an unsupported website with the current design. 

Resolution

Missed detections such as this can be a limitation of the extension method for detecting web uploads.
