Dark Visitor Client is a headless-browser crawler operated by Dark Visitors, a service that catalogues AI and automation bots on the web. The crawler is used for the service's own measurement and testing work, not for downstream commercial scraping.

Operator: Dark Visitors
Type: Research

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.

Dark Visitor Client publishes nothing Centinel can check a source against, so a match reports the name and leaves the source unconfirmed. The match tokens, verification domains, and address feeds are not published here.

Allowing or blocking it

The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, Research.
