Cxense is a bot in the SEO crawlers category, operated by Cxense.
The Cxensebot performs SEO monitoring and analysis of customer webpages.
SEO crawlers map links, keywords and technical issues for SEO tools and backlink databases. They help the tool's customers, often your competitors, rather than you. Rate limit or block the ones you do not use.
Cxense identifies itself with this user agent string:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US) AppleWebKit/537.36 (KHTML, like Gecko) cXensebot/2.0; +http://www.cxense.com/bot.html Safari/533.3 3615 155430223 0.03793830424547195 clarin.com 5.9.190.107 bot-5-9-190-107.cxensebot.comAnyone 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 Cxense 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: cXensebot Disallow: /
User-agent: cXensebot Disallow: /private/ Disallow: /search
User-agent: cXensebot Allow: /blog/ Disallow: /

User-agent: cXensebot group, Cxense ignores your User-agent: * rules, so repeat any that should still apply.cXensebot from Cxense's user agent; check Cxense'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.
Cxense works for an SEO tool's customers, often your competitors. It adds server load without readers, so rate limit or block it unless you use the tool.
Transfon Security for publishersSEO crawlers map landing pages and links for competitor research. Keep Cxense's visits out of campaign data.
Transfon Security for advertisersCxense can map your catalogue, prices and site structure for competitors. Block it unless you use the tool yourself.
Transfon Security for e-commerceAllow Cxense only if your team uses the tool; otherwise rate limit it on docs and marketing pages.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows Cxense 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.

Cxense is a bot in the SEO crawlers category, operated by Cxense. The Cxensebot performs SEO monitoring and analysis of customer webpages.
We have not confirmed whether Cxense 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: cXensebot" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "cXensebot/" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so Cxense may not follow it, and anyone can send Cxense's user agent, so a fake Cxense ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
