Prowler App / Prowler Cloud

Prowler App / Prowler Cloud is a web-based application that simplifies running Prowler across your cloud provider accounts. It provides a user-friendly interface to visualize the results and streamline your security assessments.

Attack Paths

Attack Paths automatically extends every completed AWS scan with a Neo4j graph that combines Cartography's cloud inventory with Prowler findings. The feature runs in the API worker after each scan and therefore requires:

• An accessible Neo4j instance (the Docker Compose files already ships a neo4j service).

• The following environment variables so Django and Celery can connect:

  Variable	Description	Default
  NEO4J_HOST	Hostname used by the API containers.	neo4j
  NEO4J_PORT	Bolt port exposed by Neo4j.	7687
  NEO4J_USER / NEO4J_PASSWORD	Credentials with rights to create per-tenant databases.	neo4j / neo4j_password

Every AWS provider scan will enqueue an Attack Paths ingestion job automatically. Other cloud providers will be added in future iterations.

💻 Installation

Prowler App

Prowler App offers flexible installation methods tailored to various environments:

For detailed instructions on using Prowler App, refer to the Prowler App Usage Guide.

Docker Compose

Requirements

• Docker Compose installed: https://docs.docker.com/compose/install/.

Commands

VERSION=$(curl -s https://api.github.com/repos/prowler-cloud/prowler/releases/latest | jq -r .tag_name)
curl -sLO "https://raw.githubusercontent.com/prowler-cloud/prowler/refs/tags/${VERSION}/docker-compose.yml"
# Environment variables can be customized in the .env file. Using default values in production environments is not recommended.
curl -sLO "https://raw.githubusercontent.com/prowler-cloud/prowler/refs/tags/${VERSION}/.env"
docker compose up -d

[!WARNING]
🔒 For a secure setup, the API auto-generates a unique key pair, DJANGO_TOKEN_SIGNING_KEY and DJANGO_TOKEN_VERIFYING_KEY, and stores it in ~/.config/prowler-api (non-container) or the bound Docker volume in _data/api (container). Never commit or reuse static/default keys. To rotate keys, delete the stored key files and restart the API.

Once configured, access the Prowler App at http://localhost:3000. Sign up using your email and password to get started.

Common Issues with Docker Pull Installation

[!Note]
If you want to use AWS role assumption (e.g., with the "Connect assuming IAM Role" option), you may need to mount your local .aws directory into the container as a volume (e.g., - "${HOME}/.aws:/home/prowler/.aws:ro"). There are several ways to configure credentials for Docker containers. See the Troubleshooting section for more details and examples.

You can find more information in the Troubleshooting section.
