foundational layer of any business\u2019s cybersecurity posture. One of the most overlooked vectors in this landscape is misconfigured ports, particularly those associated with <strong>SFTP<\/strong> (Secure File Transfer Protocol). A simple oversight, like leaving a default port exposed, could give attackers exactly what they need to infiltrate a network. Understanding how to configure the <strong>SFTP port<\/strong>\u2014and more importantly, how to secure it\u2014is no longer optional. <\/p>\n\n\n\n<p>Whether you\u2019re running SFTP on <strong>Windows<\/strong>, configuring custom ports like <strong>2222 or 443<\/strong>, or evaluating differences between <strong>SFTP and <\/strong><a href=\"https:\/\/www.purevpn.com\/blog\/how-to-port-forward-ssh\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>SSH ports<\/strong><\/a>, your organization\u2019s exposure is at stake.

This port ensures encrypted file transfer between client and server. Unlike traditional FTP, SFTP does not require multiple ports and is far more secure due to encryption and user authentication.<\/p>\n\n\n\n<p>When businesses ask <strong>what port is SFTP<\/strong>, the short answer is: it\u2019s <strong>port 22 by default<\/strong>, but this is fully customizable depending on your network\u2019s security configuration.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXcEU9JhfgrJDcJkhR5MfP6QGXc3_02xvsK9rsjpTodpFexqnowcirzjm_17cHfDiMmy2i1WNxghFcoJbuLeW9_uEzSVzbiMUCYBtjVZv4WP2a8OZ7By0EoMYkjbfooxlHToofc8?key=bD1T2WUrrP91aUj9uJaNOg\" alt=\"Overview of SFTP port features including default port 22, transport layer, authentication methods, and common use cases.\"\/><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>SFTP port number (default)<\/strong>: Port 22<br><\/li>\n\n\n\n<li><strong>Transport layer<\/strong>: SSH (unlike FTP over SSL\/TLS for FTPS)<br><\/li>\n\n\n\n<li><strong>Authentication<\/strong>: Passwords, <a href=\"https:\/\/www.purevpn.com\/blog\/ssh-vs-vpn\/\" target=\"_blank\" rel=\"noreferrer noopener\">SSH keys<\/a>, or both<br><\/li>\n\n\n\n<li><strong>Used in<\/strong>: Cloud backups, internal system sync, enterprise application integrations<\/li>\n<\/ul>\n\n\n\n<p>Most importantly, SFTP is not just about encryption\u2014it also includes file access, permission management, and directory listings.
