Prowler App

Prowler App is a user-friendly interface for Prowler CLI, providing a visual dashboard to monitor your cloud security posture. This tutorial will guide you through setting up and using Prowler App.

Accessing Prowler App and API Documentation

After installing Prowler App, access it at http://localhost:3000. To view the auto-generated Prowler API documentation, navigate to http://localhost:8080/api/v1/docs. This documentation provides details on available endpoints, parameters, and responses.

Note

If you are a Prowler Cloud user, you can access API docs at https://api.prowler.com/api/v1/docs

Step 1: Sign Up

Sign Up with Email

To get started, sign up using your email and password:

Sign Up with Social Login

If Social Login is enabled, you can sign up using your preferred provider (e.g., Google, GitHub).

How Social Login Works

If your email is already registered, you will be logged in, and your social account will be linked. If your email is not registered, a new account will be created using your social account email.

Enable Social Login

See how to configure Social Login for Prowler to enable this feature in your own deployments.

Step 2: Log In

Once registered, log in with your email and password to access Prowler App.

Upon logging in, the Overview page will display. At this stage, no data is present: add a provider to begin scanning your cloud environment.

Step 3: Add a Provider

To perform security scans, link a cloud provider account. Prowler supports the following providers:

• AWS

• Azure

• Google Cloud Platform (GCP)

• Kubernetes

• M365

Steps to add a provider:

1. Navigate to Settings > Cloud Providers.
2. Click Add Account to set up a new provider and provide your credentials.

Step 4: Configure the Provider

Select the cloud provider you want to scan.

Once chosen, enter the Provider UID for authentication:

• AWS: Enter your AWS Account ID.
• GCP: Enter your GCP Project ID.
• Azure: Enter your Azure Subscription ID.
• Kubernetes: Enter your Kubernetes Cluster context of your kubeconfig file.
• M365: Enter your M365 Domain ID.

Optionally, provide a Provider Alias for easier identification. Follow the instructions provided to add your credentials:

Step 4.1: AWS Credentials

For AWS, enter your AWS Account ID and choose one of the following methods to connect:

Step 4.1.1: IAM Access Keys

1. Select Connect via Credentials.

   

2. Enter your Access Key ID, Secret Access Key and optionally a Session Token:

   

Step 4.1.2: IAM Role

1. Select Connect assuming IAM Role.

   

2. Enter the Role ARN and any optional field like the AWS Access Keys to assume the role, the External ID, the Role Session Name or the Session Duration:

   

Note

Check if your AWS Security Token Service (STS) has the EU (Ireland) endpoint active. If not, we will not be able to connect to your AWS account.

If that is the case your STS configuration may look like this:

To solve this issue, please activate the EU (Ireland) STS endpoint.

Step 4.2: Azure Credentials:

For Azure, Prowler App uses a service principal application to authenticate. For more information about the process of creating and adding permissions to a service principal refer to this section. When you finish creating and adding the Entra and Subscription scope permissions to the service principal, enter the Tenant ID, Client ID and Client Secret of the service principal application.

Step 4.3: GCP Credentials

For Google Cloud, first enter your GCP Project ID and then select the authentication method you want to use:

• Service Account Authentication (Recommended)
• Application Default Credentials

Service Account Authentication is the recommended authentication method for automated systems and machine-to-machine interactions, like Prowler. For detailed information about this, refer to the Google Cloud documentation.

Step 4.3.1: Service Account Authentication

First of all, in the same project that you selected in the previous step, you need to create a service account and then generate a key in JSON format for it. For more information about this, you can follow the next Google Cloud documentation tutorials:

• Create a service account
• Generate a key for a service account

Step 4.3.2: Application Default Credentials

1. Run the following command in your terminal to authenticate with GCP:

   gcloud auth application-default login
   

2. Once authenticated, get the Client ID, Client Secret and Refresh Token from ~/.config/gcloud/application_default_credentials.

3. Paste the Client ID, Client Secret and Refresh Token into Prowler App.

Step 4.4: Kubernetes Credentials:

For Kubernetes, Prowler App uses a kubeconfig file to authenticate, paste the contents of your kubeconfig file into the Kubeconfig content field.

By default, the kubeconfig file is located at ~/.kube/config.

If you are adding an EKS, GKE, AKS or external cluster, follow these additional steps to ensure proper authentication:

Make sure your cluster allow traffic from the Prowler Cloud IP address 52.48.254.174/32

1. Apply the necessary Kubernetes resources to your EKS, GKE, AKS or external cluster (you can find the files in the kubernetes directory of the Prowler repository):

   kubectl apply -f kubernetes/prowler-sa.yaml
   kubectl apply -f kubernetes/prowler-role.yaml
   kubectl apply -f kubernetes/prowler-rolebinding.yaml
   

2. Generate a long-lived token for authentication:

   kubectl create token prowler-sa -n prowler-ns --duration=0
   

   • Security Note: The --duration=0 option generates a non-expiring token, which may pose a security risk if not managed properly. Users should decide on an appropriate expiration time based on their security policies. If a limited-time token is preferred, set --duration=<TIME> (e.g., --duration=24h).
   • Important: If the token expires, Prowler Cloud will no longer be able to authenticate with the cluster. In this case, you will need to generate a new token and remove and re-add the provider in Prowler Cloud with the updated kubeconfig.

3. Update your kubeconfig to use the ServiceAccount token:

   kubectl config set-credentials prowler-sa --token=<SA_TOKEN>
   kubectl config set-context <CONTEXT_NAME> --user=prowler-sa
   

   Replace <SA_TOKEN> with the generated token and <CONTEXT_NAME> with your KubeConfig Context Name of your EKS, GKE or AKS cluster.

4. Now you can add the modified kubeconfig in Prowler Cloud. Then test the connection.

Step 4.5: M365 Credentials

For M365, you must enter your Domain ID and choose the authentication method you want to use:

• Service Principal Authentication (Recommended)
• User Authentication (only works if the user does not have MFA enabled)

Note

User authentication with M365_USER and M365_PASSWORD is optional and will only work if the account does not enforce MFA.

For full setup instructions and requirements, check the Microsoft 365 provider requirements.

Step 5: Test Connection

After adding your credentials of your cloud account, click the Launch button to verify that Prowler App can successfully connect to your provider:

Step 6: Scan started

After successfully adding and testing your credentials, Prowler will start scanning your cloud environment, click the Go to Scans button to see the progress:

Note

Prowler will automatically scan all configured providers every 24 hours, ensuring your cloud environment stays continuously monitored.

Step 7: Monitor Scan Progress

Track the progress of your scan in the Scans section:

Step 8: Analyze the Findings

While the scan is running, start exploring the findings in these sections:

• Overview: High-level summary of the scans.

  

• Compliance: Insights into compliance status.

  

• Issues: Types of issues detected.

  

• Browse All Findings: Detailed list of findings detected, where you can filter by severity, service, and more.

  

To view all new findings that have not been seen prior to this scan, click the Delta filter and select new. To view all changed findings that have had a status change (from PASS to FAIL for example), click the Delta filter and select changed.

Step 9: Download the Outputs

Once a scan is complete, navigate to the Scan Jobs section to download the output files generated by Prowler:

You can download the output files generated by Prowler as a single zip file. This archive contains the CSV, JSON-OSCF, and HTML reports detailing the findings.

To download these files, click the Download button. This button becomes available only after the scan has finished.

The zip file unpacks into a folder named like prowler-output-<provider_id>-<timestamp>, which includes all of the above outputs. In the example below, you can see the .csv, .json, and .html reports alongside a subfolder for detailed compliance checks.

API Note

For more information about the API endpoint used by the UI to download the ZIP archive, refer to: Prowler API Reference - Download Scan Output

Step 10: Download specified compliance report

Once your scan has finished, you don’t need to grab the entire ZIP—just pull down the specific compliance report you want:

• Navigate to the Compliance section of the UI.

• Find the Framework report you need.

• Click its Download icon to retrieve that report’s CSV file with all the detailed findings.

API Note
