# Tenable Nessus

## What is Tenable Nessus?

Tenable Nessus is a vulnerability scanning platform for auditors and security analysts. Tenable Nessus pushes updated definitions to systems every day.

## Why Should You Use the Tenable Nessus Connector?

The Tenable Nessus connector provides visibility into current vulnerabilities in your environment. You can use this visibility to:

- ensure assets are managed per your security policies
- find vulnerabilities quickly and remediate

## How Does This Connector Work?

Lucidum executes read-only requests to the Tenable Nessus REST API and ingests only meta-data about Tenable Nessus assets. Lucidum does not retrieve any data stored on your assets.
