OutsellURLValidator is a bot in the monitoring and analytics bots category, operated by Outsell Corporation.
Validating client website URLS to monitor for hosting/provider changes
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.
OutsellURLValidator identifies itself with this user agent string:
OutsellURLValidatorAnyone 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.
We have not confirmed whether OutsellURLValidator 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.
User-agent: OutsellURLValidator Disallow: /
User-agent: OutsellURLValidator Disallow: /private/ Disallow: /search
User-agent: OutsellURLValidator Allow: /blog/ Disallow: /
User-agent: OutsellURLValidator Allow: / User-agent: * Disallow: /
User-agent: OutsellURLValidator group, OutsellURLValidator ignores your User-agent: * rules, so repeat any that should still apply.OutsellURLValidator from OutsellURLValidator's user agent; check Outsell Corporation's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
Allow OutsellURLValidator if it is a service you use, and keep its visits out of page views and ad requests either way.
Transfon Security for publishersOutsellURLValidator is not a person. Exclude it from campaign and conversion data so reports reflect real visitors.
Transfon Security for advertisersAllow OutsellURLValidator only if it works for your store, and keep it away from cart and checkout.
Transfon Security for e-commerceIf OutsellURLValidator is a service you use, allow it on the endpoints it needs and block it elsewhere.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows OutsellURLValidator by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

We have not confirmed whether OutsellURLValidator 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.
Add "User-agent: OutsellURLValidator" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "OutsellURLValidator" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so OutsellURLValidator may not follow it, and anyone can send OutsellURLValidator's user agent, so a fake OutsellURLValidator ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
