At a glance

Operator: Apple
Type: Feed Reader

How Centinel checks it

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

AASA-Bot 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, Feed Reader.
