Reported, not operator documented

FactSet has not published a crawler page that names Factset_spyderbot. It is listed here because a credible public source does: ai.robots.txt. Reported FactSet crawler. No vendor page.

What that means for you: the robots.txt rule on this page is the best available spelling, and a well-behaved crawler using this string will honour it, but there is no vendor statement of purpose, crawl rate or robots.txt compliance to rely on. Treat a matching request in your logs as a detection clue, not proof of who sent it, and combine the rule with a firewall rule if the traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.

What is Factset_spyderbot?

Factset_spyderbot is a developer-facing extraction agent operated by FactSet. It fetches and structures web content on behalf of applications and AI agents built on FactSet's platform. Traffic volume depends on how third-party developers configure it, so monitor your logs if you see heavy activity.

Is Factset_spyderbot safe to allow?

Factset_spyderbot is rated Caution in this directory. It is a Reported token: FactSet has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.
FactSet publishes no IP ranges or reverse-DNS pattern for Factset_spyderbot, so the user-agent string cannot be verified. Rate-limit unusual volume instead of trusting the name.

Does Factset_spyderbot respect robots.txt?

How do I verify if Factset_spyderbot is crawling my site?
Search your access logs for Factset_spyderbot (for example grep -i "Factset_spyderbot" /var/log/nginx/access.log). Because the operator publishes no IP ranges or reverse-DNS pattern, a match shows that something used the name, not that FactSet sent it.
