Agent Ready Crawlers

The field guide to every AI crawler and agent at the door, and the vendors who decide who gets in.

Bot management vendor

Centinel Analytica

In short

Centinel Analytica runs its check at the site's own edge, on whichever CDN, server or WordPress setup the customer already has, before the page is served. It claims that most requests calling themselves GPTBot are impostors, and checks them against OpenAI's published ranges. Prices are quoted per deployment, and a free audit looks only at scraping exposure.

What Centinel Analytica does for this layer

From the vendor's own pages

Centinel's GPTBot page tells site owners to verify GPTBot by checking that the source IP falls in the ranges OpenAI publishes at openai.com/gptbot.json, and shows 2026-09-30 as the last verified date. (centinelanalytica.com) Centinel integrates through AWS CloudFront, Akamai EdgeWorkers, Cloudflare Workers, Fastly Compute, Fastly VCL, NGINX or OpenResty, and WordPress. (centinelanalytica.com) In Centinel's design the site's edge asks Centinel to analyse each request before serving the page, then applies the policy decision Centinel returns. (centinelanalytica.com)

Claims the vendor makes about itself

Centinel reports that for the median organisation 94% of requests claiming to be GPTBot failed verification, measured between 14 Jul and 10 Oct 2026. (centinelanalytica.com, dated 2026-10-10) Centinel's homepage says that on a typical news site 84% of requests claiming to be GPTBot were fake, as were 14% of those claiming to be Googlebot. (centinelanalytica.com) Centinel claims it detected 8 of 8 automation tools in its September 2026 benchmark, against at most 5 for six other vendors. (centinelanalytica.com)
