Complete TCP and UDP online port scan.
What is an online port scanner?
An online port scanner detects open ports on servers, networks, and devices.
Why should businesses check for open ports?
Open ports are services that send and receive data. You may want some services to be open, such as the service hosting your website (ports 80 and 443). However, other services you may want to be private, such as databases. Scanning for open ports will alert you to any misconfigurations in your services or firewalls that have accidentally exposed private services.
