External Security Scan

[Asgorath]

We just tightened down the hatches on our firewalls and now I want a full security scan against my network across all of our IPs

Anyone know of a good website to do this for me? Or how I should do this?

If you want to pay you do go with something like Qualys.

Freebie options include ShieldsUp or you could build a nessus box and have it scan your public IP range.

I'd use nmap assuming you can sit outside the firewall.

Running Nessus would probably be best. SpaceHonkey's recommendation of running NMAP isn't necessarily bad but a port scan by itself isn't going to tell you that much. If you've got some budget, call Qualys or Foundstone and have them run a scan. If you don't have money, grab Backtrack, install Nessus and run a scan.
