Passive Vulnerability Scanner

Unique protection for BYOD, Cloud, and SCADA systems


PVS enables 100% discovery of assets plus vulnerabilities and trust relationships.

Tenable’s Passive Vulnerability Scanner™ (PVS™) is the industry’s only continuous vulnerability monitor that identifies server- and client-side vulnerabilities in new or transient assets.

PVS is essential for:

  • Full asset discovery including mobile and virtual devices and cloud-based applications
  • Identification of risks from assets, applications, and services
  • Insight into services, security vulnerabilities, suspicious network relationships, and compliance violations.

PVS is a powerful tool for finding Heartbleed and other vulnerabilities which may escape some traditional detection methods. By passively monitoring network traffic, PVS detects server and client vulnerabilities, applications, and connections.

PVS goes beyond traditional scanning. We use it to find anomalous indicators after a breach. It also allows us to provide valuable prevention services to our clients.”
