Port Spider is "nmap as a service", a security tool for network engineers.
We regularly run nmap against customers' public IP addresses, sending email when ports are newly opened or closed.
It costs one credit to activate a target IP address.
Once activated, a target will continue to be scanned for years with no further interaction or payment required.
Five credits cost $5. (While regrettable, fees limit abuse and pay for maintenance and hosting.)
