What is Secure File Transfer Protocol (SFTP)?<\/span><\/h2>\n
Secure File Transfer Protocol (SFTP) is a technical protocol<\/a> for transferring large files securely. Data<\/a> is hidden by cryptography<\/a>, and users have to prove their identity before any data is shared.<\/p>\n
The Internet<\/a> is an amazing resource, but using it to share information can be risky. SFTP gives organizations a safer way to send sensitive files over transmission control protocol<\/a> (TCP\/IP).<\/p>\n
It uses Secure Shell technology<\/a> (SSH) to create an encrypted<\/a> connection between a server<\/a> and a client. When files are transmitted over public networks<\/a>, there’s a chance they could be intercepted, causing data breaches<\/a> or compliance violations.<\/p>\n
SFTP ensures that both host<\/a> and client<\/a> are validated and authenticated while keeping sensitive information like file content, identity, and passwords<\/a> safe from prying eyes.<\/p>\n

Key Takeaways<\/span><\/h2>\n
\n
The Secure File Transfer Protocol (SFTP) enables safe and secure transfers of data over the public Internet.<\/li>\n
In today’s frequently hacked public Internet, SFTP gives businesses and governments a secure alternative to the File Transfer Protocol<\/a> (FTP).<\/li>\n
It uses the Secure Shell technology (SSH) for reliable authentication<\/a> and to encrypt data being transferred.<\/li>\n
Instead of FTP’s two port connections, SFTP needs only one, allowing any transfer to be optimized for speed and stability.<\/li>\n
For even more security, it can be used in conjunction with a VPN<\/a>, doubling up the encryption.<\/li>\n<\/ul>\n<\/div><\/div>\n
