Eliminates Critical Blind Spots

Provides deep packet inspection to continuously discover and track users, applications, cloud infrastructure, trust relationships and vulnerabilities.

Monitors Everywhere

Automatically discovers infrastructure and vulnerabilities across more technologies than any other vendor, including operational technology devices, operating systems, network devices, hypervisors, databases, tablets, phones, web servers, and cloud applications.

Real-Time Network Monitoring

Continuous Visibility:

  • Delivers continuous monitoring and assessment of an organization’s network in a non-intrusive manner
  • Monitors network traffic at the packet level to provide visibility into both server and client-side vulnerabilities
  • Scales to meet future asset discovery and vulnerability monitoring demands of proliferation of devices, including virtual systems and cloud services

Immediate Vulnerability Detection:

  • Automatic infrastructure and vulnerability assessment Identifies server- and client-side vulnerabilities in new and transient assets
  • Detects vulnerabilities on communicating systems and the protocols and applications used
  • Identifies when an application is compromised or subverted

Suspicious Traffic Identification:

  • Identifies unencrypted PII and other sensitive information in motion
  • Discovers when internal systems begin port scan of other systems
  • Highlights all interactive and encrypted network sessions
  • Spots which ports served and browsed for each individual system

Asset Discovery:

  • Operational Technology devices and applications
  • Servers
  • Endpoints
  • Web applications
  • Network devices
  • Virtual- and cloud-based devices
  • BYOD/mobile devices
  • Jailbroken iOS devices

Compliance and Deployment

PCI DSS Compliance

The PCI DSS requires accurate and comprehensive identification of all systems involved in the transmission, processing or storage of credit card data. These systems collectively comprise the "cardholder data environment" (CDE) where PCI DSS controls must be consistently applied and validated on an annual basis. Organizations also must provide evidence of procedures to maintain the integrity of the CDE. Nessus Network Monitor not only monitors known data flows in/out of the CDE but also identifies undocumented data flows, particularly of unencrypted payment card information.

Deployment Options

Nessus Network Monitor is included as a sensor with Tenable.io®, Industrial Security, and Tenable.sc™. It is offered at two performance levels: 1 Gbps for monitoring small networks and network segments; and 10 Gbps, which extends Nessus Network Monitor to high-performance datacenters and internet ingress/egress points.
