In Combined Mode, what does "Appliance Only" mean regarding the Protection Module?

In Combined Mode, the term "Appliance Only" refers to a specific operational characteristic of the Protection Module. When it states that the Protection Module is only provided by the Virtual Appliance, it indicates that in this mode, the ability to deliver protection through the specified module is exclusive to the Virtual Appliance.

This setup is crucial because it means that end users are relying solely on the Virtual Appliance for those protection capabilities, which can be part of a broader strategy for managing security. By centralizing the protection through the Virtual Appliance, it allows for streamlined management and potentially more consistent application of security policies across your environment.

This setup also highlights the architecture choices in network security, where depending on deployment scenarios, organizations might lean on either agents or appliances to fulfill different security roles effectively while ensuring they have the necessary capabilities to protect against threats.
