VM-Series is applicable for which of the following traffic scenarios?

1. Inbound

2. North-south and east-west

3. East-west only

4. Outbound

The correct answer is: North-south and east-west

The VM-Series is specifically designed to provide comprehensive security for both north-south and east-west traffic scenarios. North-south traffic refers to the data flow between external networks (like the internet) and internal networks, such as data centers or virtual private clouds. This is typically where the need for robust perimeter security and threat prevention is essential. East-west traffic, on the other hand, refers to data movement between different segments or resources within the internal network itself, for example, between virtual machines or applications hosted on the same cloud environment. As organizations increasingly adopt cloud architectures and dynamic environments, the significance of securing this internal traffic has grown, as threats can easily propagate in such scenarios. The VM-Series effectively secures both types of traffic by integrating features like intrusion prevention, malware protection, and application control, ensuring that organizations can maintain a secure environment regardless of whether traffic is entering or moving within the network. This dual capability makes the VM-Series highly applicable and valuable in modern networking scenarios.
