Can AI assistants read globalsecurity.org?

Measured on 2026-09-13 by asking the site 5 times — once as a browser, once as each of the 4 crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Meta AI, Apple Intelligence and Doubao — and comparing what came back. The AI-training opt-out tokens that never crawl are read from robots.txt instead. Tranco rank #16,083.

F42 / 100
0 of 4 crawlers can read this page.
More readable than 4% of the 47,934 sites measured so far. No JSON-LD.

Cloudflare answers for this domain. Where a crawler above is refused while robots.txt allows it, the rule is applied by that edge, not written by the site — see how often each edge does this.

What to change, in order

  1. Let in the 1 crawler your own robots.txt already allows+1 crawler
    OAI-SearchBot is turned away before reading the page (served a bot challenge instead of the page), while robots.txt permits it — so this block is not written in your site. Cloudflare answers for this domain. Cloudflare applies AI-crawler blocking at the edge, independently of robots.txt (Security → Bots, plus the managed robots.txt feature). https://developers.cloudflare.com/bots/concepts/bot/ Fixing it takes this domain from 0 to 1 of 4 crawlers.
  2. Declare the facts in JSON-LD
    There is no JSON-LD on the page, so every fact — who you are, what you sell, the price — has to be guessed out of the prose and the layout. A schema.org block is the difference between being quoted correctly and being paraphrased.
  3. Publish llms.txt
    llms.txt is missing, so an assistant has to discover the site by following links. llms.txt is the emerging convention for telling an assistant which pages actually matter.
  4. 3 crawlers are named and refused in robots.txt — a deliberate choice
    ClaudeBot, GPTBot, PerplexityBot are blocked by a rule that names them. Nothing to fix here: this page records what is true, not what should be. It is listed so the deliberate part of the block is not confused with the accidental part above.

Method. 5 live HTTP requests (one per crawler, one as a browser) plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each, from a single vantage point. Blocking AI crawlers is a legitimate choice, not a failure: this page records what is true, not what should be. Domain comes from the Tranco research list. One page per domain — the homepage — is audited.
