About VarsuiteCore

Website Management Simplified

Monitoring bots check uptime, performance and page changes on behalf of a site owner or a third party. Allow the services you run yourself and exclude them from analytics so they do not inflate page views.

VarsuiteCore user agent

VarsuiteCore identifies itself with this user agent string:

  • Varsuite Core - https://vs-core.com

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 VarsuiteCore in robots.txt

We have not confirmed whether VarsuiteCore 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 VarsuiteCore from the whole site

User-agent: Varsuite
Disallow: /

Block VarsuiteCore from some folders

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

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

Allow VarsuiteCore and block other crawlers

User-agent: Varsuite
Allow: /

User-agent: *
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: Varsuite group, VarsuiteCore ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Varsuite from VarsuiteCore's user agent; check Varsuite Core Ltd'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. VarsuiteCore may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that VarsuiteCore 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 VarsuiteCore's user agent, and a scraper using it is not bound by Varsuite Core Ltd's robots.txt policy. Only checking the source network tells a real VarsuiteCore from a fake one.

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

Frequently asked questions

What is VarsuiteCore?

VarsuiteCore is a bot in the monitoring and analytics bots category, operated by Varsuite Core Ltd. Website Management Simplified

Does VarsuiteCore respect robots.txt?

We have not confirmed whether VarsuiteCore follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block VarsuiteCore?

Add "User-agent: Varsuite" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "Varsuite Core" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block VarsuiteCore?

No. robots.txt is voluntary, so VarsuiteCore may not follow it, and anyone can send VarsuiteCore's user agent, so a fake VarsuiteCore ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.

Should I block VarsuiteCore?

Monitoring bots check uptime, performance and page changes on behalf of a site owner or a third party. Allow the services you run yourself and exclude them from analytics so they do not inflate page views.
