This page describes how Forseti is built, and how the components of Forseti fit
Forseti gives you tools to understand all the resources you have in Google Cloud
Platform (GCP). The core Forseti modules work together to provide complete
information so you can take action to secure resources and minimize
- Inventory regularly collects data from your GCP resources and makes it
available to other modules.
- Scanner periodically compares your rules about GCP resource policies against
the policies collected by Inventory, and saves the output for your review.
- Explain helps you understand, test, and develop Cloud Identity and Access
Management (Cloud IAM) policies.
- Enforcer uses Google Cloud APIs to change resource policy state to match the
state you define.
- Notifier keeps you up to date about Forseti findings and actions.
