In the discovery phase of pentesting, it is common that when scanning an IP or IP range with nmap, the firewall/IPS may block your IP address and show the port as closed or filtered, which can lead to a false negative, i.e. a failure to detect a service that is actually available on the Internet. It could also be the case that you are auditing a web service and a WAF detects a payload or behavior that also restricts access from your IP address, which could be considered that of an attacker.

There are numerous sites that allow you to perform a remote scan of the most common ports online. We can quickly check whether your IP address has been banned or the service is down, without the need to change connections by trying different VPNs or making anonymous requests.
