CallingID Toolbar is a toolbar for Internet Explorer and Firefox, that automatically displays owner information of the website you are currently visiting. It includes the physical address, company name and a risk assessment, based on a variety of verification tests. Unlike regular Whois tools, that simply use the owner information provided by the registrar, CallingID verifies that the organization actually exists at the address it claims to, using external sources, like yellow pages, Dun and Bradstreet and several other databases. The program can protect you from phishing scams, and other online dangers.
