In which type of physical deployment is a ProxySG out-of-path but still has potential visibility to all traffic?

In a virtually inline deployment, the ProxySG operates out-of-path but can still capture and analyze traffic effectively. This configuration allows the proxy to be placed strategically within the network, using techniques such as port mirroring, to gain visibility into all traffic without being directly in the data path.

This setup provides several advantages, including minimizing latency and preventing bottlenecks that sometimes occur with inline deployments where the proxy is directly in the traffic flow. The virtually inline architecture allows for monitoring and enforcement of policies on the data being transmitted, ensuring that the ProxySG can carry out its functions such as content filtering, threat protection, and data loss prevention without hindering throughput.

Furthermore, this deployment style supports environments where highly available applications require uninterrupted service. Being out-of-path helps in maintaining application performance while still providing the necessary monitoring and security capabilities.

In contrast, other deployment types, such as transparent inline, involve the proxy being directly integrated into the traffic path, which might not be suitable for all scenarios. Standalone configurations may not handle traffic flow effectively, and the out-of-path deployment specifically refers to a scenario where the proxy does not analyze traffic in real-time, thereby lacking the same visibility provided in the virtually inline approach.
