This feature will prevent all ports from being scanned. But you can also whitelist a series of specific ports for website scanning.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">If some websites use Nmap for external scannings, such as https:\/\/whatleaks.site\/, then this feature will not take effect. However, as far as we know, most sites will not use Nmap for legal reasons.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">In computer science, a port is a communication endpoint. When an application is running on a computer, it opens a port that corresponds to the address at which the application interacts with other applications. <br><br><\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Example:<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>The TeamViewer opens ports:<\/strong> 80, 443, and 5938 (TCP)<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>RDP (Remote Desktop Protocol) opens port:<\/strong> 3389 (TCP\/UDP)<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">The port number can be any number between 0 and 65535.<\/mark><\/p>\n\n\n\n<p class=\"has-medium-font-size\">Websites can scan locally open ports through web sockets, detect which ports a computer has opened, and understand what programs the user is running. Our technical team has confirmed that both eBay and Amazon have taken advantage of this technology.<br><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"996\" height=\"691\" src=\"https:\/\/www.vmlogin.us\/help\/wp-content\/uploads\/2023\/01\/en-23.png\" alt=\"\" class=\"wp-image-2310\" srcset=\"https:\/\/www.vmlogin.us\/help\/wp-content\/uploads\/2023\/01\/en-23.png 996w, https:\/\/www.vmlogin.us\/help\/wp-content\/uploads\/2023\/01\/en-23-300x208.png 300w, https:\/\/www.vmlogin.us\/help\/wp-content\/uploads\/2023\/01\/en-23-768x533.png 768w\" sizes=\"auto, (max-width: 996px) 100vw, 996px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Users can turn on the port scanning protection function [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[],"class_list":["post-1546","post","type-post","status-publish","format-standard","hentry","category-fingerprint"],"_links":{"self":[{"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/posts\/1546","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/comments?post=1546"}],"version-history":[{"count":5,"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/posts\/1546\/revisions"}],"predecessor-version":[{"id":2355,"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/posts\/1546\/revisions\/2355"}],"wp:attachment":[{"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/media?parent=1546"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/categories?post=1546"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vmlogin.us\/help\/wp-json\/wp\/v2\/tags?post=1546"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
