Open Port Scanner(check open port of any website online)
This tool help you to check open ports of your website.
Check either port is open or not.
Open ports are used by applications and services and, as any piece of code, they may have vulnerabilities or bugs. The more applications and services run using open ports for Internet communication, the higher the risk of one of them having a vulnerability that can be exploited.
An open port is an attack surface. The daemon that is listing on a port, could be vulnerable to a buffer overflow, or another remotely exploitable vulnerability.
