# Access Transparency

[Access Transparency](https://center.yandex.cloud/security/transparency/) is an automated tool providing insights into the actions Yandex Cloud engineers take with your organization's resources during maintenance, when handling [support requests](../../support/overview.md), or for security purposes. With this tool, you can gain visibility and control over the actions of Yandex Cloud engineers.

To connect and use Access Transparency, your [organization](../../organization/quickstart.md) must be linked to a [billing account](../../billing/concepts/billing-account.md). Follow [this guide](../../billing/operations/change-organization.md) to link your organization to a billing account.

Once your organization links a billing account, select it in the [Access Transparency](https://center.yandex.cloud/security/transparency/) module.

To manage an Access Transparency subscription, you need the `access-transparency.subscriptionManager` role. To specify a billing account when connecting Access Transparency, you need the `access-transparency.billingProvider` role. `access-transparency.admin` and `access-transparency.editor` include both these roles. For more information, see [Roles for Access Transparency data analysis](../security/access-transparency-roles.md).

Key Access Transparency features:

* Collects and analyzes data on the actions taken by Yandex Cloud engineers with the organization's resources.
* Provides access to security verdicts of specific user sessions.
* Automatically alerts you to suspicious activity or security breaches:

    * A specialized model based on YandexGPT analyzes the logs of Yandex Cloud personnel activity with your organization's resources.
    * If the model detects security risks in a Yandex Cloud employee’s actions, a request is automatically created to verify these actions.
    * If you do not agree with the analysis or assessment, you can escalate the request to have the session reviewed by Yandex Cloud information security team.
