Free port check: see whether RDP, SMB, VNC, databases or other dangerous ports of your own connection are reachable from the internet. Nothing is stored.
Background

Every port reachable from the internet is a potential attack surface. Remote access (RDP, VNC), file sharing (SMB) and databases in particular are scanned around the clock for weak passwords and known vulnerabilities. The check shows which of these services are reachable from outside on your own connection.
