GCP Firewall Scanner

A simple tool designed to scan Google Cloud Platform (GCP) firewall rules and identify any unused rules.

Usage

Print tables in a terminal.

go run ./main.go --projectID=${ProjectID} --format table

Create a CSV file with the results.

go run ./main.go --projectID=${ProjectID} --format csv

Efficiently scan only the running instances.

go run ./main.go --projectID=${ProjectID} --format csv --running

If you choose to output the results as a CSV file, these two files will be created in your current directory.

• instances_${projectID}.csv
• firewalls_${projectID}.csv
