Communication with Site24x7 servers

The On-Premise Poller communicates with Site24x7 servers but the servers have no access to the machine in which the On-Premise Poller is installed.

Ports and domains

If the On-Premise Poller is installed in a secure network, make sure you allow access to a list of domains and ports in your firewall to facilitate communication between your server and the Site24x7 central server.

To add more:

1. dms.zoho.com - The On-Premise Poller receives messages and commands related to both the On-Premise Poller and the monitor (activate,suspend, etc) from this domain.
   
2. pluspoller.site24x7.com - The On-Premise Poller sends reports to this domain.
   

Accessibility

Ensure that Site24x7 servers are accessible from the On-Premise Poller.

SSL encryption

Site24x7 On-Premise Poller uses SSL encryption to transfer data. The On-Premise Poller communicates with the Site24x7 server through port 443 and uses a one-way secured communication. The On-Premise Poller is firewall-friendly and it is not required to open inbound ports in your firewall.
