Network Security Groups

Network Security Groups (NSGs) serve as centralized firewall policy managers, enabling the filtering of network traffic to and from virtual network resources within a given Virtual Data Center (VDC).

An NSG contains bidirectional security firewall rules that allow ingress (incoming) and egress (outgoing) network traffic for Network Interface Cards (NICs) or Virtual Machine (VM) resources configured as NSG members. For each rule, you can specify the source IP address, destination IP address, port, protocol, etc.

New data center location: Network Security Groups are now available in IONOS Cloud's EN 50600-certified data center in Frankfurt, Germany, enhancing high availability, redundancy, and operational security. If you have a data center in the new location Germany / Frankfurt am Main (de/fra/2), then select the respective datacenter when you create Network Security Groups.
