My suggestion is that you get to know the individuals which are being hired.

We currently have an outsourced firewall solution (*gasp* *groan*).  I am not
going to name any company names but they are a huge ISP (global).  This
situation arose because no one here had a clue about internet security (before I
came...blah blah).  Overall it hasn't been terrible, but I have the following
problems:

   Lack of technical skill of the ISP / firewall manager.  Even though they are
huge they still have clueless people in the NOC.  One example that comes to mind
is one we experienced last year - we were getting piss-poor performance of our
proxy server during normal business hours.  My theory - Pentium 90 BSDi box is
too small to handle the load - it should be replaced.  Outsource company's
theory - we had our DNS (we have split DNS) misconfigured.  After 6 weeks the
outsourcing company concluded that the Pentium should be replaced by an
ultraSparc.  Voila!  Problem resolved.  *grrrrr*

   Lack of information for us.  We can't even touch the keyboard on the
firewall, let alone get a shell.  Even though I intuitively diagnosed the
problem above it would have been easier to prove to the ISP / outsourcing
company I was correct if I had access to the machine.

   Backdoors on the firwall - the ISP has a modem on the firewall!!!!

Overall, I think this is a good option for companies that have low cluefulness
amongst their employees, or can't give 24/7 attention to a firewall using only
internal employees.  But there are some security risks - namely you can't see
what they are doing and there are reasons to be worried about incompetence.

We will soon be switching to a more pleasant agreement with a ISP / firewall
service vendor.  In this agreement they will "own" the hardware and the OS and
be responsible for patching and replacing busted kit - but the firewall software
/ rulesets / configuration will only be controlled by internal staff.  Getting
this compromise was the conclusion of over a year of campaigning by me (I've
only worked here a year and a half).
