SFTP vs FTPS-Is it time to replace your old process as above user? If so, you can switch from standard FTP file transfers to safer and more powerful methods such as SFTP and FTPS. But if you're not sure which one to use, you're not alone. Many users are wondering which FTP protocol to use in their organization. Simplify confusion. In this article, we will examine SFTP and FTPS protocols to determine which one is better for your unique situation and needs.

What is SFTP?

SFTP (FTP over SSH) is a secure FTP protocol that sends files over secure shell (SSH) and provides a high level of protection for file transfers. SFTP implements AES, Triple DES and other algorithms to encrypt data flowing between systems. It also offers several ways to verify connections with user IDs and passwords, SSH keys or password combinations, and SSH keys for organizations that require more powerful authentication.

Do you need to meet legal and regulatory requirements? SFTP can also help you control the requirements for file transfers on your list for PCI DSS, HIPAA, GDPR and more.

What is FTPS?

FTPS (FTP over SSL) is a secure FTP protocol that allows you to protect and modify your files with trading partners, employees and customers. Like SFTP, FTPS also implements powerful algorithms such as AES and Triple DES to encrypt key file transfers. To verify the connections, FTPS uses a combination of user ID, password, and / or certificate to verify the authenticity of the system.

If compatibility is a problem, you can achieve various file transfer requirements with FTPS, including PCI DSS, HIPAA, HITECH, SOX and status privacy laws.
When to Choose SFTP Against FTPS?

When SFTP and FTPS are both secure protocols with the same protection, when is it best to use one? The answer depends. Your selections come to your organization's IT infrastructure, commercial partner requirements, how you want to verify file transfers, and which ports you want to use.
When to use SFTP:

SFTP has an advantage over FTPS when it comes to authentication and firewall. For example, when verifying a link, you can:

1. Use the user ID and password to connect to the SFTP server; OR
2. Use an SSH key with password for additional authentication or instead

Key-based authentication requires you to create an SSH key pair in advance, so keep in mind that you plan to use SFTP. If you plan to use the SSH key to authenticate the connection, you may want to see Key Management and Certificates with your SFTP Client / Server. SFTP vs FTPS

Considering the ease of implementation, SFTP wins. SFTP, which is a very easy firewall protocol, requires an open port (port 22) to send initial authentication, to issue commands and to transfer files between itself and other servers. When to Use FTPS:

If you need to use FTPS by a trading partner, or if you want to use the certificate to verify the connections, FTPS will be the best choice for secure file transfer.

FTPS uses TLS to encrypt server connections (and SSL is now considered to be unsafe by SSL DSS and most industry standards). X.509 certificates are used to verify the identity of this connection. The name of the publisher includes information that can be defined, such as the name of the subject, the details of the subject's public key, and its signature.SFTP vs FTPS
When using certificates, they are considered reliable if they are signed by a known certification authority (CA) or signed by a trading partner. Certificates signed by the CA can be easily verified using a chain of trust included in the standard. SFTP vs FTPS. To verify a self-signed certificate, you must have a copy of the trade partner's public certificate in your trusted keystore.

There is a disadvantage. If you select FTPS for your organization, the FTPS may be difficult to connect through a high-security firewall. FTPS uses several port numbers for implicit and open connection types; each time a file transfer or directory listing request is made, another port opens. This can cause damage to your network and may make you vulnerable if you are not SFTP vs FTPS careful and alert.
