πŸ†” Okta - Prowler App

Okta lands in Prowler App.

Authenticate with read-only OAuth credentials and scan your Okta tenant from the App in minutes.

The signon service also grows from 1 to 5 checks. Four new medium-severity checks cover the rest of the DISA STIG Okta IDaaS V1R2 Global Session Policy and sign-in banner controls:

  • signon_global_session_lifetime_18h β€” V-273203 / OKTA-APP-001665. Global session maximum lifetime must be 18 hours or less.
  • signon_global_session_cookies_not_persistent β€” V-273206 / OKTA-APP-001710. Global session cookies must not be persistent across browser restarts.
  • signon_global_session_policy_network_zone_enforced β€” V-279691 / OKTA-APP-003242. Global Session Policy rules must enforce a network zone constraint.
  • signon_dod_warning_banner_configured β€” V-273192 / OKTA-APP-000200. The customized sign-in page must display the DoD-mandated warning banner.

[!NOTE]
The banner check requires reading Okta brands and customized sign-in pages, so okta.brands.read is now part of DEFAULT_SCOPES. Existing Okta service apps must grant it before upgrading.

Read more in our Okta provider documentation.

Explore all Okta checks at Prowler Hub.

🧾 Finding Evidence

The finding detail drawer in the Prowler App now exposes a dedicated "Resource Metadata / Evidence" tab, backed by a new resource.metadata attribute on /api/v1/findings?include=resources.

The tab surfaces the raw resource attributes Prowler captured at scan time, the evidence behind every PASS / FAIL, in one click from the finding. No more jumping out to the source-of-truth console just to confirm what the scanner saw.

πŸ€– Prowler for Claude Code

Prowler ships a Claude Code plugin and marketplace so Claude can drive end-to-end cloud security and compliance assessments through the Prowler MCP server, against a Prowler Cloud-connected account.

Install it from inside Claude Code:

/plugin marketplace add prowler-cloud/prowler
/plugin install prowler@prowler-plugins

From there, Claude can walk an provider through a chosen security or industry framework and remediate findings until the framework is compliant.

[!NOTE]
The plugin is in preview and under active development. Please report issues on GitHub or join the Slack community for feedback.

Read more in our Prowler for Claude Code documentation.

πŸ“§ Google Workspace β€” Sites, Marketplace, Additional services, Groups

The Google Workspace provider gains four new services and six new checks through the Cloud Identity Policy API:

  • Sites β€” sites_service_disabled: verifies legacy Google Sites is disabled for the organization so users cannot publish unmanaged Sites pages.
  • Additional services β€” additionalservices_external_groups_disabled: verifies the Additional Google services > Google Groups toggle is disabled, blocking users from accessing external groups from their corporate account.
  • Marketplace β€” marketplace_apps_access_restricted: verifies third-party Marketplace apps are restricted (admin-approved only or fully blocked) instead of letting any user install arbitrary apps.
  • Groups β€” 3 new checks for Google Groups for Business:
    Β - groups_creation_restricted β€” verifies group creation is restricted to admins, preventing user-created groups that bypass access reviews.
    Β - groups_external_access_restricted β€” verifies groups cannot be made accessible to users outside the organization.
    Β - groups_view_conversations_restricted β€” verifies non-members cannot view group conversations.

πŸ†• New Checks

AWS

  • ses_identity_dkim_enabled β€” verifies DKIM signing is enabled on every SES identity (domain or email) so outbound email is cryptographically signed and resistant to spoofing. Thanks to @mohamedsolaiman!
  • sagemaker_models_registry_in_use β€” verifies at least one SageMaker Model Package Group has an approved model package, enforcing ML governance workflows through the SageMaker Model Registry. Thanks to @cascioli!

M365

  • entra_app_registration_client_secret_unused β€” flags Entra ID app registration client secrets that have never been used or have not been used for a configurable amount of days, so dormant credentials can be revoked before they leak. Thanks to @AlexanderSanin and @PrettyFox0!

GCP

  • cloudsql_instance_cmek_encryption_enabled β€” verifies Cloud SQL instances are encrypted with a customer-managed encryption key (CMEK) instead of Google-managed defaults. Thanks to @s1ns3nz0!

πŸ” Security Updates

  • MCP Server β€” fastmcp 2.14.0 β†’ 3.2.4 for GHSA-5h2m-4q8j-pqpj, GHSA-rww4-4w9c-7733 and GHSA-vv7q-7jx5-f767. The bump also pulls fixed jaraco.context, python-multipart and starlette, and drops the vulnerable lupa and urllib3 transitive dependencies.

UI

πŸš€ Added

  • okta provider support with OAuth 2.0 private-key JWT credentials form (client ID + PEM private key) (#11213)
  • "Resource Metadata / Evidence" tab in the finding detail drawer (#11187)

🐞 Fixed

  • Resource detail panels: metadata editor now scrolls internally with the minimal scrollbar across the finding drawer and /resources/:id, tab labels truncate with tooltips on narrow widths, and "View in AWS Console" moved from the resource UID row to the resource actions menu (#11325)

API

πŸš€ Added

  • okta provider support (#11184)
  • resource.metadata attribute included in /api/v1/findings?include=resources (#11187)

SDK

πŸš€ Added

  • Sites, Additional Google services, and Marketplace checks for Google Workspace provider using the Cloud Identity Policy API (#11281)
  • entra_app_registration_client_secret_unused check for M365 provider (#11232)
  • cloudsql_instance_cmek_encryption_enabled check for GCP provider (#11023)
  • Google Workspace Groups service with 3 new checks (#11186)
  • ses_identity_dkim_enabled check for AWS provider (#10923)
  • sagemaker_models_registry_in_use check for AWS provider, verifying that at least one SageMaker Model Package Group has an approved model package to enforce ML governance workflows (#11196)
  • signon_dod_warning_banner_configured, signon_global_session_lifetime_18h, signon_global_session_cookies_not_persistent and signon_global_session_policy_network_zone_enforced checks for Okta provider (#11224)

πŸ”„ Changed

  • OktaProvider.test_connection accepts an optional provider_id (org domain) and raises OktaInvalidProviderIdError (14007) when it doesn't match the authenticated org β€” guards against stored UID drifting from the credentials' org (#11184)
  • Use single-quoted strings for credential variables in the M365 provider PowerShell session, following PowerShell best practices for literal values (#9997)

🐞 Fixed

  • OCI Audit service configuration lookup when the configured region differs from the tenancy home region (#10347)
  • Container image now uses an absolute ENTRYPOINT (/home/prowler/.venv/bin/prowler) so it works under any runtime --workdir. The relative entrypoint was breaking the official GitHub Action (prowler-cloud/[email protected]) and any docker run with a custom -w (#11313)

MCP

πŸ” Security

  • fastmcp from 2.14.0 to 3.2.4 for GHSA-5h2m-4q8j-pqpj, GHSA-rww4-4w9c-7733, and GHSA-vv7q-7jx5-f767, which also pulls fixed jaraco.context, python-multipart, starlette, and drops the vulnerable lupa/urllib3 transitive deps (#11284)
