[nzlug] Urgent: Load balancing / network monitoring / security

[Hosting Direct Ltd]

Hi everyone.
I run Hosting Direct Ltd, some may know that I run the FreeB web hosting
plan, I also run a web site called Foxy Hub, this is a auction web site.
I am having some real issues at the moment with the way I did my setup and
managing my 45RU of servers, I did the network setup with some skilled Linux
friends:
For security we use dual firewalls at network entry with IP Tables, and SNMP
monitoring back to a server, have MRTG bandwidth monitoring setup also etc.
We use Nagios2 to keep an eye on all the servers in the racks.
We use ultra monkey to do the HA load balancing for foxy hub.
BUT GUESS WHAT!? My servers still got hacked, 20% of my network is still
down, my site foxy hub site still wont run due to a DOS and to many MYSQL
connection.
Can you believe that!? Anyway it's a Sunday and I need to make a big move
this week to really secure my network services and future proof them, My
FreeB hosting servers have also hacked to death, the servers are dead or
dieing and I can't jump stat it's heart the usual way!! Lol! :( (mad panic!)

Anyway, down to the reason of this mail, I am looking for some advise from
someone who knows what to do in these situations, I am happy to pay for your
time for consulting...

At the moment I am looking into exinda.com appliances to take over nagios2's
job and policy control, snmp and network security, is this the right move?
Go for the corporate solutions EEK!?

Any advise, suggestions, or phone calls really appreciated.

Thanks in advance.
