Tenable Core + Tenable Nessus

To install and run Tenable Core + Tenable Nessus, your system must meet requirements established for Tenable Nessus and Tenable Core.

Tenable Core + Tenable Nessus Hardware Requirements

Enterprise networks can vary in performance, capacity, protocols, and overall activity. Resource requirements to consider for Tenable Nessus deployments include raw network speed, the size of the network being monitored, and the Tenable Nessus configuration.

Tenable Nessus Scanners and Tenable Nessus Professional Hardware Requirements

Note: The Tenable Core Disk space requirement identifies the need for 30 GB of disk space, but this does not include additional space for the OS, etc. which can bring the total to 82 GB for the virtual machine itself.

Note: Only one virtualized Tenable Nessus scanner can be run on any physical host. Tenable Nessus relies on low-level network operations and requires full access to the host's network interface controller (NIC). In a virtualization environment (for example, Hyper-V, Docker), this can cause incorrect scanner behavior, or host instability, if more than one virtualized Tenable Nessus scanner attempts to share a single physical NIC.

Scenario

Minimum Recommended Hardware

Scanning up to 50,000 hosts per scan

CPU: 4 2GHz cores

Memory: 4 GB RAM (8 GB RAM recommended)

Disk space: 30 GB, not including space used by the host operating system

Note: Your usage (e.g., scan results, plugin updates, and logs) increases the amount of disk space needed over time.

Scanning more than 50,000 hosts per scan

CPU: 8 2GHz cores

Memory: 8 GB RAM (16 GB RAM recommended)

Disk space: 30 GB, not including space used by the host operating system

Note: Your usage (e.g., scan results, plugin updates, and logs) increases the amount of disk space needed over time.

Tenable Nessus Manager Hardware Requirements

Scenario

Minimum Recommended Hardware

Nessus Manager with 0-10,000 agents

CPU: 4 2GHz cores

Memory: 16 GB RAM

Disk space: 5 GB per 5,000 agents per concurrent scan

Note: Scan results and plugin updates require more disk space over time.

Nessus Manager with 10,001-20,000 agents

 

CPU: 8 2GHz cores

Memory: 32 GB RAM

Disk space: 5 GB per 5,000 agents per concurrent scan

Note: Scan results and plugin updates require more disk space over time.

Note: Engage with your Tenable representative for large deployments.
