Rapport validates the IP address of each protected website you browse, to make sure that you are not under a pharming attack. In a pharming attack, the user is directed to a fraudulent website even if the user types the correct website address.

In some scenarios, Rapport is unable to contact its verification server to verify the website's IP address. This usually happens because of a personal firewall or an antivirus solution that blocks Rapport's communication with the verification server. When this happens, Rapport presents the following Warning dialog box.
