Centralized Policy Management: NSGs offered by IONOS act as a centralized policy manager where firewall policy templates can be defined for a given Virtual Data Center (VDC).
Default and Custom NSGs: NSGs are of two types: Default and Custom.
Stateful Virtual Firewall: Each security group acts as a stateful virtual firewall, controlling both inbound and outbound traffic.
Integration with NIC-based firewall rules: You can complement the NSG rules by configuring NIC-based firewall rules, providing additional flexibility and customization options.
Fine-Grained Access Control: NSGs enable fine-grained access control at the level of Virtual Machines (VMs) and Network Interface Cards (NICs).
Streamlined Management: Centralized policy management streamlines the management of firewall rules across multiple network interfaces and VM instances.
Flexibility and Customization: Customization options for Default and Custom NSGs provide flexibility in managing firewall rules.
Enhanced Security: Stateful virtual firewall and fine-grained access control ensure that only authorized traffic, based on defined protocols and port numbers, is allowed to flow through.
Enhanced Customer Experience: You can get a more intuitive way of handling firewall rules for a VDC. NSGs address the need by enhancing the overall customer experience on the IONOS Cloud platform.
