Closed Ports = Service Disruption

When critical ports go down, your services become inaccessible. Port monitoring ensures you catch failures immediately.

Service Outages

Closed ports prevent users from accessing your applications, databases, or APIs.

Firewall Issues

Misconfigurations or firewall changes can block critical ports without warning.

Late Detection

Without monitoring, you only discover port issues after users complain about downtime.
