Secure SFTP Alternative: Replacing Windows FTP Server

Published {$created} by Carsten Blum

Many organizations and individuals rely on Windows FTP Server for file transfer needs. However, Windows FTP Server has limitations in security and reliability. A robust SFTP alternative offers significant advantages. This post details why migrating to SFTP, specifically with a managed service like ftpGrid, is a smart choice.

Security Concerns with Windows FTP Server

Windows FTP Server uses a plaintext protocol, making it vulnerable to interception and unauthorized access. While FTPS (FTP over SSL/TLS) exists, configuring and maintaining SSL certificates can be complex and error-prone. SFTP, based on SSH, inherently offers much stronger security through encryption and key-based authentication. Plain FTP fundamentally lacks the security features that modern file transfer demands. At ftpGrid, we strongly recommend avoiding password authentication (see ftp-101-sftp-keys-vs-passwords-security/) and prioritize SSH key based authentication.
