I personally am a bit sceptical of NSS and other similar so-called
third party tests. From a user perspective, you can not get any
information from them without paying big $. From a vendor perspective,
you cannot participate without paying big $ (i have heard this same
story from more than one vendor). Smells a bit like a racket to me.
Bottom line is that if you are able, build a small test lab (many open
source options), look into getting demo loaners from various vendors
and test for your self. Understand your environment, potential attack
entry points and unique vulnerabilities. I feel this would be a far
greater use of the time and money that an NSS report would cost.

I understand your concerns, they are the same ones voiced by many. It's
not for me to say who is a good resource and who is not and how the
various testing vendors go about their testing. I don't have enough
detailed information on a lot of that information anyway. However, I do
know quite a lot about in-house testing.

The following needs to be true:

 1. You need to know exactly what you are doing.
 2. The test lab needs to be set up correctly with actual testing
equipment. (including traffic generation equipment)
 3. The attacks need to be valid (see number 1).
 4. The normal traffic needs to be valid and must emulate real-world
situations (see number 1).
 5. You must be able to combine 3 and 4. (see number 1)
 6. You need to test thoroughly, and more than once.
 7. Your test results should be reproducible by someone else.
 8. Essentially, you should follow the scientific method, see [0].
 9. There is no such thing as a "small" test lab.
 10. It will never be perfect.

At this point, you might realize that the time involved and cost is not
insignificant and it certainly makes the cost from a testing vendor to
buy a report seem much more reasonable. Of course, you should try to
test the equipment you are about to buy as you suggest as well,
especially since no two networks are alike, but I wouldn't rely on only
that testing to make a decision. (just as I wouldn't rely on only a
testing vendors report to make a decision)
