Features and Benefits

Features

• 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).

Benefits

• 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.
