Baiduspider-render is a web crawler operated by Baidu, China's largest search engine, specifically designed to render and index JavaScript-heavy pages. This variant processes dynamic web content to help Baidu understand and rank modern websites that rely on client-side rendering.

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.
Reverse DNS: The client address resolves to a hostname the operator controls, and that hostname resolves back to the same address.

A request that passes one of these checks is Baiduspider-render itself. One that only matches the user agent is reported as unverified. 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, Search Engine.
