nessus file reader by LimberDuck (pronounced ˈlɪm.bɚ dʌk) is a CLI tool
and python module created to quickly parse nessus files containing the results
of scans performed by using Nessus and Tenable.sc by (C) Tenable, Inc. This module will let
you get data through functions grouped into categories like file, scan, host
and plugin to get specific information from the provided nessus scan files.
- read data from nessus files containing results of scans performed by using Nessus and Tenable.sc by (C) Tenable, Inc.
- use it in CLI to check quickly e.g. quality of your scan
- use it as python module
Check code examples.
Note: It's advisable to use python virtual environment for below instructions. Read more about python virtual environment in The Hitchhiker’s Guide to Python!
Read about virtualenvwrapper in The Hitchhiker’s Guide to Python!: virtualenvwrapper provides a set of commands which makes working with virtual environments much more pleasant.
