Virtual Environment Monitoring


Visibility Into Your Virtualized Infrastructure

Tenable offers a range of virtualization security solutions. Nessus® and SecurityCenter™ Continuous View provide periodic assessments and continuous monitoring of your virtualized environment.

Nessus performs audits against the VMware vSphere platform, as well as the software running on it. With Nessus, users have complete visibility to address virtual machine (VM) sprawl, unpatched software, and misconfigured ports and services.

In addition, SecurityCenter Continuous View identifies the virtual infrastructure and associated risk as soon as it comes online without having to wait for the next scheduled scan.


Network-based Vulnerability Scanning

  • Without credentials, Nessus determines the number of VMware ESX / ESXi / vCenter / View virtual machines on your network and their location.
  • After detecting VMs, Nessus identifies vulnerabilities using network-based vulnerability checks.

Patch Auditing

After VMs are identified, Nessus scans them using credentials to perform patch auditing and pull configuration information for hosted VMs. Nessus reports the missing patches for each ESX / ESXi / vCenter / View virtual machine that is scanned.

In addition, Nessus can log in and pull information from VMs, such as active and inactive VMs on the host. This information is useful to continually audit your virtualized environment, and acting on it can help prevent VM sprawl.

Configuration and Compliance Auditing

Nessus performs VMware configuration and compliance audits, and supports ESXi 4.x / 5.x and vCenter 4.x / 5.x.

Tenable supplies Nessus users with customizable compliance auditing files, which:

  • Identifies missing patches for each virtual system in your environment
  • Validates patching by cross checking discovered vulnerabilities with major patch management systems including VMware GO.
  • Tracks trust relationships with other physical and virtual systems to correlate exposure to connected virtual and physical infrastructure

Respond and Track

  • Helps prioritize response to issues with full context of virtual and physical systems
  • Continuously monitors for threats, vulnerabilities, and malware on hosts and virtual systems to improve security response
  • Identifies critical changes to your host and virtual systems and reassesses risk posture for faster response
