About Usercentricsbot

Consent management platform scanner for GDPR/DMA/CCPA compliance.

Security scanners probe sites for vulnerabilities, certificates and exposed services. Some are research projects, some are vendors you hired. Allow your own scanners and block the rest at the WAF.

Usercentricsbot user agent

Usercentricsbot identifies itself with this user agent string:

  • Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/605.1.15 (KHTML, like Gecko) Chrome/129.0.6668.29 Safari/605.1.15 (compatible; Usercentricsbot/1.0; +http://usercentrics.com/dps-scanner/)

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block Usercentricsbot in robots.txt

We have not confirmed whether Usercentricsbot follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block Usercentricsbot from the whole site

User-agent: Usercentrics
Disallow: /

Block Usercentricsbot from some folders

User-agent: Usercentrics
Disallow: /private/
Disallow: /search

Allow Usercentricsbot only on some folders

User-agent: Usercentrics
Allow: /blog/
Disallow: /

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: Usercentrics group, Usercentricsbot ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Usercentrics from Usercentricsbot's user agent; check Usercentrics GmbH's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. Usercentricsbot may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that Usercentricsbot follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send Usercentricsbot's user agent, and a scraper using it is not bound by Usercentrics GmbH's robots.txt policy. Only checking the source network tells a real Usercentricsbot from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
