The security group on our client asks to close the port 8022 because it is no secure, How can we close it?

| 8022 | Dynatrace Managed UI and REST API (NGINX) | Port 8022 can be closed to traffic coming from outside the Dynatrace cluster. This port can be used as an equivalent to 443 if usage of a non-privileged port is required. |

You could do it using firewalld or iptables on Linux or Windows Firewall on Windows, of course also you can do it with external equipment.

do you mean not using the port 8022 for managed service? or simply block access? Blocking access can be updated in iptables or client firewall policies. Make sure its allowed for Dynatrace cluster ips
