NIC-based Firewall

Activate and configure a Firewall for each Network Interface Card (NIC) to better protect your servers from attacks. IONOS Cloud Firewalls can filter incoming (ingress), outgoing (egress), or bidirectional traffic. When configuring firewalls, define appropriate rules to filter traffic accordingly.

Note: We recommend using Network Security Groups (NSGs) for centralized and fine-grained firewall management in Virtual Data Centers (VDCs). It will enable you to control and monitor your network traffic efficiently.
