Prowler Cloud & Prowler Local Server

Prowler Cloud and Prowler Local Server, its self-hosted open-source version, are web applications that simplify running Prowler across your cloud provider accounts. They provide 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 graph that combines Cartography's cloud inventory with Prowler findings. The feature runs in the API worker after each scan.

Two graph backends are supported as the long-lived sink:

• Neo4j (default; the Docker Compose files already ship a neo4j service).
• Amazon Neptune (cloud-managed; opt-in).

Select the sink with ATTACK_PATHS_SINK_DATABASE (neo4j or neptune; default neo4j).

Note: Cartography ingestion always uses a temporary Neo4j database, regardless of the configured sink. The NEO4J_* variables below must remain set even when ATTACK_PATHS_SINK_DATABASE=neptune.

Neo4j sink

Neptune sink

Neptune authenticates with SigV4 using the standard boto3 credential chain. The worker's IAM role (or AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY) supplies the credentials. There is no Neptune password variable.

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