What this means
OPEN
A service accepted the connection. Anything reachable from the public Internet should be intentional, authenticated and kept up to date.
CLOSED
The target responded, but nothing is listening on this port. Connections are actively refused.
FILTERED
No response was received. A firewall, router or upstream provider may be silently dropping traffic to this port.
UNSUPPORTED
XPOZ could not reliably test this port from the current scanning environment, so no result is reported.
Important
- Port Check tests up to ten TCP ports at a point in time. A closed or filtered result does not guarantee that your device, network, or systems are secure.
- XPOZ tests only the IP currently associated with this browser.
- Results are not saved to an application database.
