ProtoMon is a robust server monitoring software intended to check your servers and let you know when some of them aren't available.

It supports the following TCP protocols:
- ICMP
- HTTP(HTTPS)
- FTP(FTPS)
- POP3(POP3S)
- IMAP(S)
- SMTP(SMTPS)
- Telnet(SSH)
- SFTP
- Custom TCP connections

If a server is not responding, the program will perform any of these actions:
- send a notification e-mail message
- display a pop-up notification window
- play a sound

Also ProtoMon can do some additional actions, such as filter the downloaded content, check the Internet connection, download a file while checking an FTP or SFTP server, send a test e-mail message while checking an SMTP server, execute the scripts via Telnet or SSH, etc.

The program keeps network monitoring statistics, thus you can see it both in text and graphical forms.

You can see the server statuses and statistics remotely, using your web browser. This can be done in two different ways. ProtoMon contains a built-in web server, and you can start it and connect directly. Or you can configure the program to create the static web pages within required intervals and copy them to the required folder. This allows you to use your default web server (Apache, IIS, or any else) to access this information.
