Our FTP server does support FTPS/FTPES protocols for securing your transfer using a 2048 BIT certificate.  In order to access these protocols you will need an FTP client that supports them like FileZilla which can be downloaded from http://filezilla-project.org/ free of charge.  Our FTPS/FTPES service is offered on port 990 and can be accessed by directing your FTP client to ftps://ftp.satoritechsolutions.com/ or ftpes://ftp.satoritechsolutions.com/
