i agree with this. it's often much easier to find a bug than to exploit
it (see strange heap overflows and the like), and i also don't have the
time to spend days on disassembling and looking for attack vectors (and
i'm sure that other people will have more fun doing just that).
what i criticize is that *lots* of companies (at least here in my
vicinity) are selling cheap "vulnerability assessments" which actually
are nothing more than automated security scans. this leads to the
customer feeling safe when he's really wide open to attacks. often,
these people's networks can be rooted in no time.
sure, you don't have to be uber-31337 to do penetration tests (i'm
certainly not), but it should definitely go beyond the
"scan--+--google-for-exploit" approach.

regards,
