Qualys Network Passive Sensor
With Qualys Network Passive Sensor (NPS), you can automatically detect and profile devices connected to your network, eliminating blind spots across your IT environment. NPS monitors network activity without any active probing of devices to detect active assets in your network.
Virtual Appliance supports a maximum throughput of 2 Gbps. It can be scaled up or down depending on its allocated resources. For more details, refer to the Appendix section.
Network Requirements and Configuration
Make sure that your network follows the prerequisites mentioned in the following table:
Before you Begin - Mirror the Traffic
You need to feed traffic to the appliance by mirroring it (using a physical tap or mirror port). Connect the mirrored port to the appliance's sniffing interface. This step is required to see discovered assets.
Network Passive Sensor supports mirror traffic for SPAN, RSPAN, and ERSPAN methods. For more information, refer to the Deployment Guide.
Get Started
Once you complete the setup, the NPS starts discovering assets on your network. It takes just a couple of minutes.
Perform the following steps to set up the Network Passive Sensor:
