Best Site for External Firewall Probing/Reporting?

Hi All,

I'm looking for recommendations on applications or web sites to use in testing a client's Internet facing firewall for potential security issues (i.e. open ports, etc.).

I've used Shields Up! in the past ( but I'm suspecting there must be something better out there.

Your recommendations?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It really depends on what you need, if it's just a small office or something like that then ShieldsUp is fine; if you need a certified solution for compliance etc then you could use QualysGuard from

Thanks for the responses.  Qualys is too pricey and ShieldsUp! doesn't give enough detail - I'm looking for something in the middle of the two.  Any other recommendations?



p.s. didn't do enough, IMO - they merely gave me a "your ports are fine" message after a scan.  I'm looking for a detailed report to hand a client after a scan has been completed.
Unfortunately good reports from online service providers come at a price ..

You could try the following:

To be honest, I would simply download Nessus from (free registration as long as you don't want the professional feed subscription or around $500 if you do), install it on a box, connect it to the internet and point it at the target. You will get a decent report which you can edit and provide to your client.
