Moving from white-hat research toward gray, scan your competitor’s IP address to see what ports are open. If you don’t have access to Nmap (http://insecure.org/nmap), there’s a limited, Web-based, port-scanning tool at T1 Shopper (t1shopper.com/tools/port-scanner).

It’s unlikely anyone is running open or anonymous FTP these days, but you can check if you want. Of course, only access data that a site provides is open to everyone.
