TCP Port/Telnet Monitoring—Frequently Asked Questions

Below are some of the most common questions about TCP Port/Telnet monitoring. If you have additional questions, contact us.

TCP is one of the most used protocols on the Internet. The port monitor checks if a device is waiting for and accepting connections on a specified TCP port.

When a connection to the port cannot be established, our monitoring agents alert you through various mechanisms like email, SMS, SNMP consoles, and more.

Our agents attempt a connection with a specific port on a server, using the TCP protocol. If the connection is not accepted, the service might be down. This process mirrors a Telnet application.

We offer real-time monitoring, immediate alerts, and a user-centric approach. With our TCP Port/Telnet Monitoring, ensure every port on your network is always operational and ready for communication.
