What is the default state of the ESXi firewall?

The default state of the ESXi firewall is activated. This means that the firewall is not only present as a security feature but is also turned on to help protect the ESXi host from unauthorized access and potential threats. When the firewall is activated, it allows for the configuration of rules that dictate what traffic can enter or exit the ESXi host. This is essential in a virtualized environment, where multiple VMs might be operating and could be at risk if not properly secured.

While the terms "enabled" and "activated" may seem synonymous in some contexts, in the case of the ESXi firewall, “activated” is specifically used to indicate the operational status of the firewall. This security feature is critical for maintaining robust protection in the virtual infrastructure. Being aware of the default state helps administrators understand their security posture and whether any adjustments are necessary to align with organizational security policies or operational needs.
