  VPN's don't provide security.  Neither does SSH, or SSL, or any
other acronym.  They can be used as part of a security strategy, but
you can't just sprinkle some encryption on something and say you're
secure.  Any of them can result in a security exposure if used poorly.

  Typically and generically, the term "VPN" means a network link
between two controlled networks, transported over the public Internet,
with some kind of encryption and authentication to defend against
hijacking and snooping.  An unrestricted VPN between two systems with
different security postures is a security exposure, as it's a hole
punched through your security perimiter.  Depending on what one is
trying to do, putting a firewall on the VPN link may be an effective
countermeasure.

  SFTP or some kind of HTTP-over-SSL thing might provide the ability
to more tightly restrict what the client end can access, or make it
easier to enact such restrictions.  Thus, a tightly restricted web
interface might be more secure than a wide open VPN.  Or the other way
around.

  VPN, SFTP, HTTP-over-SSL can all be vulnerable to various attacks,
especially if one uses passwords for authentication and ignores host
authentication.  Password guessing, man-in-the-middle, DNS hijacking,
etc.
