Last Modified: 2014-05-01

I would love to test from Internet if i have any leaks in my customer's firewalls.

Can you recommend any free or not free tester? Is there any leagal issues to consider. I don't want to break in anywhere but I would love to test that the firewalls are good.

One of my costomers reported that he had a Anti Virus warning of "Nmap TCP scan" where remote address were public IP.

It's free and it's good!

FYI - When you scan an IP, use the config toolbox/icon to the right to pick the ports to scan otherwise by default it won't. For instance, you can pick all ports 1-65535, or just look for certain services like FTP on port 21 or RDP on 3389, etc.....

You might use Nexpose, Retina, Metasploit. There are some free versions for modest needs.  You'd need to review their offerings.  That said, they work great and generate reports that will choke a horse!

Retina is fantastic, I've used that one (but the paid, not free).

I've used Retina before as well as Nesus and Tenable.  However, he wants a scan from outside of his network in. So unless he loads something and goes external he wont be able to do it ib the maner he wants. Hence why I mentioned Tripwire's Secure Scan since its hosted outside his network.  He can monitor thw scan inside his network whule hw initaes the scan.

Just initiate a scan from your home PC if you want a scan from the outside inward. Or I just initiate the scan from a remote office and make sure traffic goes out the WAN.

I really didn't want to use any scanners not recommend here. I'll start with Tripwire Secure Scan.
