Thanks for the information, they look like a great option.

We are still evaluating all our options for block lists, but for sure
it's one of the measures we started taking recently.
We really avoided for years the idea of blocking any country as such,
because it seems that is unfair to the legitimate Internauts in those
countries, but sadly it has come down to that.

That looks very cool. Definitively worth collaborating with!

We're a tiny 10 people operation and we manage about half a dozen
servers. We have one dedicate sysadmin, and even so I have to dedicate
at least 20% of my time to the security issues. This does not count DB
maintenance and overall health checks of the platform. About 50% or
more of my admin's time goes into fine tuning our security measures,
security patches, etc. - that plus about 20% of my time which I could
be doing much more productive stuff. For such a small company to me
that is a huge cost! You could say that maybe probably don't have all
the security expertise, and that's why we invest so much human time
into this, but whichever way it's still a lot of lost money. I think
that hiring this out would probably be more expensive and in my
experience these security "experts" many time know less than we do -
especially when it comes down to our FBSD servers!

I can only image how this is affecting companies that are much larger
than us. Well that is, if they really take care and analyze attacks
and logs, or maybe they hire fewer but more expert security teams...
probably, but it's still very costly IMHO.
