About Panopta

Panopta is an uptime monitoring service acquired by Fortinet.

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.

Panopta user agent

Panopta identifies itself with this user agent string:

  • Panopta v1.1

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 Panopta in robots.txt

We have not confirmed whether Panopta 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 Panopta from the whole site

User-agent: Panopta
Disallow: /

Block Panopta from some folders

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

Allow Panopta only on some folders

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

Allow Panopta and block other crawlers

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

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

Frequently asked questions

What is Panopta?

Panopta is a bot in the monitoring and analytics bots category, operated by Panopta. Panopta is an uptime monitoring service acquired by Fortinet.

Does Panopta respect robots.txt?

We have not confirmed whether Panopta 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 Panopta?

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

Is robots.txt enough to block Panopta?

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

Should I block Panopta?

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.
