This guide provides comprehensive instructions to configure SAML-based Single Sign-On (SSO) in Prowler App. This configuration allows users to authenticate using the organization’s Identity Provider (IdP). This document is divided into two main sections:
  • User Guide: For organization administrators to configure SAML SSO through Prowler App.
  • Developer and Administrator Guide: For developers and system administrators running self-hosted Prowler App instances, providing technical details on environment configuration, API usage, and testing.

​
User Guide Configuration

Follow these steps to enable and configure SAML SSO for an organization.

​
Key Features

Prowler can be integrated with SAML SSO identity providers such as Okta to enable single sign-on for the organization’s users. The Prowler SAML integration currently supports the following features:
  • IdP-Initiated SSO: Users can initiate login from their Identity Provider’s dashboard.
  • SP-Initiated SSO: Users can initiate login directly from the Prowler login page.
  • Just-in-Time Provisioning: Users from the organization signing into Prowler for the first time will be automatically created.
Deactivate SAMLIf the SAML configuration is removed, users who previously authenticated via SAML will need to reset their password to regain access using standard login. This occurs because accounts no longer have valid authentication credentials without the SAML integration.

​
Prerequisites

  • Administrator access to the Prowler organization is required.
  • Administrative access to the SAML 2.0 compliant Identity Provider (e.g., Okta, Azure AD, Google Workspace) is necessary.

​
Configuration Steps

​
Step 1: Access Profile Settings

To access the account settings, click the “Account” button in the top-right corner of Prowler App, or navigate directly to https://cloud.prowler.com/profile (or http://localhost:3000/profile for local setups). Access Profile Settings

​
Step 2: Enable SAML Integration

On the profile page, find the “SAML SSO Integration” card and click “Enable” to begin the configuration process. Enable SAML Integration
Choose Your MethodUse Step 3A (Generic Method) for any SAML 2.0 compliant Identity Provider or when you need custom configuration.Use Step 3B (Okta App Catalog) if you’re using Okta and want a simplified setup process with pre-configured settings.

​
Step 3A: Configure the Identity Provider (IdP) - Generic

Prowler App displays the SAML configuration information needed to configure the IdP. Use this information to create a new SAML application in the IdP.
  1. Assertion Consumer Service (ACS) URL: The endpoint in Prowler that will receive the SAML assertion from the IdP.
  2. Audience URI (Entity ID): A unique identifier for the Prowler application (Service Provider).
To configure the IdP, copy the ACS URL and Audience URI from Prowler App and use them to set up a new SAML application. IdP configuration
IdP ConfigurationThe exact steps for configuring an IdP vary depending on the provider (Okta, Azure AD, etc.). Please refer to the IdP’s documentation for instructions on creating a SAML application. For SSO integration with Azure AD / Entra ID, see our Entra ID configuration instructions.

​
Step 3B: Configure Prowler from App Catalog - Okta

Instead of creating a custom SAML integration, Okta administrators can configure Prowler Cloud directly from Okta’s application catalog:
  1. Access App Catalog: Navigate to the IdP’s application catalog (e.g., Browse App Catalog in Okta). Browse App Catalog
  2. Search for Prowler Cloud: Use the search functionality to find “Prowler Cloud” in the app catalog. The official Prowler Cloud application will appear in the search results. Search for Prowler
  3. Select Prowler Cloud Application: Click on the Prowler Cloud application from the search results to view its details page. Prowler Application Details
  4. Add Integration: Click the “Add Integration” button to begin adding Prowler Cloud to the organization’s applications.
  5. Configure General Settings: In the “Add Prowler Cloud” configuration screen, the integration automatically configures the necessary settings. Add Prowler Configuration
  6. Assign Users: Navigate to the Assignments tab and assign the appropriate users or groups to the Prowler application by clicking “Assign” and selecting “Assign to People” or “Assign to Groups”.
With this step, the Okta app catalog configuration is complete. Users can now access Prowler Cloud using either IdP-initiated or SP-initiated SSO flows. If you used Step 3B (Okta App Catalog), jump to Step 6: Save and Verify Configuration.

​
Step 4: Configure Attribute Mapping in the IdP

For Prowler App to correctly identify and provision users, configure the IdP to send the following attributes in the SAML assertion:
Attribute NameDescriptionRequired
firstNameThe user’s first name.Yes
lastNameThe user’s last name.Yes
userTypeThe Prowler role to be assigned to the user (e.g., admin, auditor). If a role with that name already exists, it will be used; otherwise, a new role called no_permissions will be created with minimal permissions. Role permissions can be edited in the RBAC Management tab.No
companyNameThe user’s company name. This is automatically populated if the IdP sends an organization attribute.No
IdP Attribute MappingNote that the attribute name is just an example and may be different depending on the IdP. For instance, if the IdP provides a ‘division’ attribute, it can be mapped to ‘userType’.IdP configuration
Dynamic UpdatesProwler App updates these attributes each time a user logs in. Any changes made in the Identity Provider (IdP) will be reflected when the user logs in again.

​
Step 5: Upload IdP Metadata to Prowler

Once the IdP is configured, it provides a metadata XML file. This file contains the IdP’s configuration information, such as its public key and login URL. To complete the Prowler App configuration:
  1. Return to the Prowler SAML configuration page.
  2. Enter the email domain for the organization (e.g., mycompany.com). Prowler App uses this to identify users who should authenticate via SAML.
  3. Upload the metadata XML file downloaded from the IdP.
Configure Prowler with IdP Metadata

​
Step 6: Save and Verify Configuration

Click the “Save” button to complete the setup. The “SAML Integration” card will now display an “Active” status, indicating the configuration is complete and enabled. Verify Integration Status
IdP ConfigurationThe exact steps for configuring an IdP vary depending on the provider (Okta, Azure AD, etc.). Please refer to the IdP’s documentation for instructions on creating a SAML application.
Remove SAML Configuration
SAML SSO can be disabled by removing the existing configuration from the integration panel. Remove SAML configuration

​
IdP-Initiated SSO

Once SAML SSO is configured, users can access Prowler Cloud directly from their Identity Provider’s dashboard:
  1. Navigate to the IdP dashboard or portal
  2. Click on the Prowler Cloud application tile
  3. The system automatically authenticates users and redirects them to Prowler Cloud
This method is convenient for users who primarily work from the IdP portal and prefer a seamless single-click access.

​
SP-Initiated SSO

Users can also initiate the login process directly from Prowler’s login page:
  1. Navigate to the Prowler login page
  2. Click “Continue with SAML SSO”
  3. Enter their email address from the configured domain
  4. The system redirects users to the IdP for authentication
  5. After successful authentication, users are returned to Prowler App
This method is useful when users bookmark Prowler or navigate directly to the application.

​
Developer and Administrator Guide

This section provides technical details for developers and administrators of self-hosted Prowler instances.

​
Environment Configuration

For self-hosted deployments, several environment variables must be configured to ensure SAML SSO functions correctly. These variables are typically set in an .env file.
VariableDescriptionExample
API_BASE_URLThe base URL of the Prowler API instance.http://mycompany.prowler/api/v1
DJANGO_ALLOWED_HOSTSA comma-separated list of hostnames that the Django backend will accept requests from. Include any domains used to access the Prowler API.localhost,127.0.0.1,prowler-api,mycompany.prowler
AUTH_URLThe base URL of the Prowler web UI. This is used to construct the callback URL after authentication.http://mycompany.prowler
SAML_SSO_CALLBACK_URLThe full callback URL where users are redirected after authenticating with the IdP. It is typically constructed using the AUTH_URL.${AUTH_URL}/api/auth/callback/saml
After modifying these variables, the Prowler API must be restarted for the changes to take effect.

​
SAML API Reference

Prowler provides a REST API to manage SAML configurations programmatically.
  • Endpoint: /api/v1/saml-config
  • Methods:
    • GET: Retrieve the current SAML configuration for the tenant.
    • POST: Create a new SAML configuration.
    • PATCH: Update an existing SAML configuration.
    • DELETE: Remove the SAML configuration.
API DocumentationFor detailed information on using the API, refer to the Prowler API Reference.

​
SAML Initiate Endpoint

  • Endpoint: POST /api/v1/accounts/saml/initiate/
  • Description: This endpoint initiates the SAML login flow. It takes an email address, determines if the domain has a SAML configuration, and redirects the user to the appropriate IdP login page. It is primarily designed for browser-based flows.

​
Testing SAML Integration

Follow these steps to test a SAML integration in a development environment.

​
1. Expose the Local Environment

Since the IdP needs to send requests to the local Prowler instance, it must be exposed to the internet. A tool like ngrok can be used for this purpose. To start ngrok, run the following command: 
ngrok http 8080
This command provides a public URL (e.g., https://<random-string>.ngrok.io) that forwards to the local server on port 8080.

​
2. Update DJANGO_ALLOWED_HOSTS

To allow requests from ngrok, add its URL to the DJANGO_ALLOWED_HOSTS environment variable. 
DJANGO_ALLOWED_HOSTS=localhost,127.0.0.1,prowler-api,*.ngrok.io

​
3. Configure the IdP

When configuring the IdP for testing, use the ngrok URL for the ACS URL: https://<your-ngrok-url>/api/v1/accounts/saml/<YOUR_DOMAIN>/acs/

​
4. Configure Prowler via API

To create a SAML configuration for testing, use curl. Replace placeholders with actual data. 
curl --location 'http://localhost:8080/api/v1/saml-config' \
--header 'Content-Type: application/vnd.api+json' \
--header 'Accept: application/vnd.api+json' \
--header 'Authorization: Bearer <YOUR_API_TOKEN>' \
--data '{
  "data": {
    "type": "saml-configurations",
    "attributes": {
      "email_domain": "yourdomain.com",
      "metadata_xml": "<PASTE_YOUR_IDP_METADATA_XML_HERE>"
    }
  }
}'

​
5. Initiate Login Flow

To test the end-to-end flow, construct the login URL and open it in a browser. This starts the IdP-initiated login flow. https://<your-ngrok-url>/api/v1/accounts/saml/<YOUR_DOMAIN>/login/ If successful, the user will be redirected back to the Prowler application with a valid session.
