AlertsiteBySmartbear is a bot in the monitoring and analytics bots category, operated by Smartbear.
Alertsite by Smartbear is the HTTP monitoring probe that monitors its customers websites for availability and performance anomalies.
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.
AlertsiteBySmartbear identifies itself with this user agent string:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322; AlertSite)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.
We have not confirmed whether AlertsiteBySmartbear 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: AlertSite Disallow: /
User-agent: AlertSite Disallow: /private/ Disallow: /search
User-agent: AlertSite Allow: /blog/ Disallow: /
User-agent: AlertSite Allow: / User-agent: * Disallow: /
User-agent: AlertSite group, AlertsiteBySmartbear ignores your User-agent: * rules, so repeat any that should still apply.AlertSite from AlertsiteBySmartbear's user agent; check Smartbear'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 AlertsiteBySmartbear if it is a service you use, and keep its visits out of page views and ad requests either way.
Transfon Security for publishersAlertsiteBySmartbear is not a person. Exclude it from campaign and conversion data so reports reflect real visitors.
Transfon Security for advertisersAllow AlertsiteBySmartbear only if it works for your store, and keep it away from cart and checkout.
Transfon Security for e-commerceIf AlertsiteBySmartbear 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 AlertsiteBySmartbear 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.

AlertsiteBySmartbear is a bot in the monitoring and analytics bots category, operated by Smartbear. Alertsite by Smartbear is the HTTP monitoring probe that monitors its customers websites for availability and performance anomalies.
We have not confirmed whether AlertsiteBySmartbear 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: AlertSite" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "AlertSite" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so AlertsiteBySmartbear may not follow it, and anyone can send AlertsiteBySmartbear's user agent, so a fake AlertsiteBySmartbear ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
