Tenable Nessus Agent for Mac

Summary

Tenable’s Nessus Agent for macOS is a lightweight endpoint component that teams can deploy to extend Nessus vulnerability scanning to individual Macs. Offered under a no-cost license option, the agent collects system data and helps surface security weaknesses so organizations can prioritize remediation. When paired with a Nessus scanner, it enables continuous assessment and near-real-time visibility into risk across managed devices.

How it operates

The agent runs quietly on the host, gathering inventory and vulnerability information and sending that data back to a central Nessus server for analysis. It supports scheduled and on-demand checks, so scans can be automated to fit operational workflows. Configuration and management are handled from the scanner side, reducing the need for hands-on maintenance at each endpoint.

Core capabilities

• Integrates with other security platforms and feeds results into centralized workflows
• Offers flexible reporting formats, templates, and export options for different audiences
• Performs automated vulnerability discovery and continuous monitoring of macOS systems

Who should consider it

This solution fits security teams and IT administrators who need a scalable way to extend vulnerability coverage to Mac endpoints without heavy manual effort. It’s suitable for small environments that want a free option as well as larger organizations that will integrate the agent into a broader vulnerability management program.
