What is FTPS Implicit?
What is Implicit FTPS? Implicit FTPS is a method of FTPS that allows clients to connect to an implicit port (Port 990) which already has secure connections baked in without requesting for there to be one. Implicit FTPS makes use of a dedicated port in order to allow for port 21 to be left open.
