Passive Vulnerability Scanner Enterprise - subscription license (1 year) - 10 GB capacity

The Tenable Passive Vulnerability Scanner (PVS) monitors network traffic at the packet layer to determine topology and identify services, security vulnerabilities, suspicious network relationships, and compliance violations.

Passive Vulnerability Scanner provides visibility into both server and client-side vulnerabilities, discovers the use of common protocols and services, and performs full asset discovery for both IPv4 and IPv6, and even on hybrid networks.
