It is used to securely transfer files between a client and a server while protecting data such as login credentials and file contents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">FTPS is based on the traditional FTP structure but adds a security layer on top of it.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 ez-toc-wrap-left counter-hierarchy ez-toc-counter ez-toc-custom

class=\"wp-block-list\">\n<li>the client connects to the server<\/li>\n\n\n\n<li>authentication is performed using username and password or certificates<\/li>\n\n\n\n<li>data is transferred between the client and server<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The difference is that FTPS encrypts the connection using SSL\/TLS, protecting both control commands and file data during transmission.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Encryption_in_FTPS\"><\/span>Encryption in FTPS<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p

of login credentials<\/li>\n\n\n\n<li>encryption of file contents<\/li>\n\n\n\n<li>optional use of digital certificates for authentication<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This

990<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Both modes provide encryption, but explicit FTPS is more commonly used in modern systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

compared with SFTP, but they are different technologies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>FTPS is FTP with SSL\/TLS encryption<\/li>\n\n\n\n<li>SFTP is a separate protocol based on SSH<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">They are not compatible with each other and use different connection methods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Practical_use_cases\"><\/span>Practical use cases<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">FTPS is used for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>secure file transfers in legacy FTP environments<\/li>\n\n\n\n<li>integration with systems that already support FTP infrastructure<\/li>\n\n\n\n<li>transferring sensitive data with encryption requirements<\/li>\n\n\n\n<li>business systems requiring certificate-based authentication<\/li>\n<\/ul>\n\n\n\n<h2

class=\"wp-block-paragraph\">FTPS requires additional configuration compared to SFTP, including certificate setup and firewall port management.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because it uses multiple communication channels, FTPS may require more complex firewall configuration than SSH-based alternatives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In modern hosting environments such as mybox, SFTP is often preferred for simplicity, while FTPS may still be supported for compatibility with older systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

It improves the security of traditional FTP while maintaining its structure, but is more complex to configure than newer alternatives like SFTP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"template":"","format":"standard","manualknowledgebasecat":[25],"manual_kb_tag":[372,1725,410,1726,412,834,1247,1548,1693,1697,1717,1718,1719,1720,1721,1722,1723,1724],"class_list":["post-833","manual_kb","type-manual_kb","status-publish","format-standard","hentry","manualknowledgebasecat-hosting","manual_kb_tag-ssl-certificate","manual_kb_tag-port-99","manual_kb_tag-secure-file-transfer","manual_kb_tag-port-98","manual_kb_tag-ftps","manual_kb_tag-file-transfer-protocol","manual_kb_tag-tls-certificate","manual_kb_tag-encrypted-connection","manual_kb_tag-ftp-protocol","manual_kb_tag-active-mode-ftp","manual_kb_tag-ftp-secure","manual_kb_tag-ftp-over-ssl","manual_kb_tag-ftp-over-tls","manual_kb_tag-implicit-ftps","manual_kb_tag-explicit-ftps","manual_kb_tag-encrypted-protocols","manual_kb_tag-control-channel","manual_kb_tag-data-channel"],"_links":{"self":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb"}],"about":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/types\/manual_kb"}],"author":[{"embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":1,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/833\/revisions"}],"predecessor-version":[{"id":9049,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/833\/revisions\/9049"}],"wp:attachment":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/media?parent=833"}],"wp:term":[{"taxonomy":"manualknowledgebasecat","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manualknowledgebasecat?post=833"},{"taxonomy":"manual_kb_tag","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb_tag?post=833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
