n8n-nodes-nessus

This is an n8n community node for interacting with Tenable Nessus vulnerability scanners, bringing comprehensive vulnerability management capabilities to n8n workflows.

n8n Nessus Node

About

This node provides a comprehensive interface to Tenable Nessus vulnerability scanners within n8n, enabling security teams to automate vulnerability management workflows. Our goal is to make Nessus functionality seamlessly available in n8n, allowing users to integrate vulnerability scanning into their automation pipelines.

Inspiration and Credits

This project is inspired by and references the excellent pyTenable Python library created by Tenable, Inc. The pyTenable library provides a pythonic interface into Tenable's platform APIs and serves as our primary reference for API interactions and functionality.

We've adapted the pyTenable library's approach and functionality to work within the n8n ecosystem, translating Python patterns to TypeScript and n8n's node architecture.

Installation

Follow the installation guide in the n8n community nodes documentation.
