Looking for a secure ftp sw

[Padiyath Sreekumaran]

   Hello,
   At present we are using ProFTPD on our ftp server.
   On this server we have anonymous ftp access as well
   as access to pre defined project users(via projectname/password).
   These people also access via ftp. Our security person likes to have
   sftp instead of ftp access to these project accounts. I have NOT
configured 
   this server.
   I would like to know the following:

   Is it possible to use annonymous ftp as well as sftp
   access to the same ftp server? If possible how one has to
   configure FTP server?

   Is there a better FTP SW(more secure) than ProFTPD for server usage?

   We are using RedHat as OS on the FTP server.

   Thanks in advance,
     Kumar
