Simple FTP ServiceDNS

Using a custom DNS name

Point your own hostname at your Simple FTP Service with a CNAME - what works for SFTP and plain FTP, and why FTPS needs a different approach.
Updated August 27, 2026

You can give your users a hostname on your own domain by adding a CNAME record that points at your service's regional hostname:

sftp.mycompany.com.  CNAME  sfs-eu-west-1.docevent.io.

What works

  • SFTP and SCP - works as-is. SSH does not care what name the client used to reach the server; host-key verification still passes (the host key is the same).
  • Plain FTP - works as-is.

Why FTPS does not work over a CNAME

With FTPS, the connection is upgraded to TLS and the server presents a certificate for sfs-<region>.docevent.io. Your users connected to sftp.mycompany.com, so the names do not match and their client reports an invalid certificate.

Options for FTPS on your own domain

  1. A dedicated IP with your own certificate - we can add a hosted dedicated IP address to your plan, with your own TLS certificate and SSH key on a dedicated instance. Contact support to ask about options.
  2. Self-host the server - run the Self-Hosted Simple FTP Server in your own network with your own certificate (-tlscert / -tlskey), while services and users stay managed from the DocEvent console.
