Go2Cloud offers two approaches to firewall protection:
Platform firewall: This can be enabled directly in your server settings through the control panel. It provides network-level filtering before traffic reaches your server. An additional charge applies for this service.
Software firewall: You can install and configure a software firewall within your operating system at no extra cost. Common options include iptables or ufw on Linux, and Windows Firewall on Windows Server.
For the best security, we recommend using both approaches. The platform firewall provides a first layer of protection, while a software firewall gives you granular control over the rules applied to your server.
