Personal data includes: full name, email, and phone number. How to set up: 1. Go to the **Settings tab → Security → Security Policy** and enable **Hide customer personal data**.

2. Control data visibility by granting or removing the **View and edit personal data** permission for the relevant staff or security groups.

For more flexible control, assign the ***Unmask personal data*** permission to a user. This allows them to view customer data on the customer’s page.

Every use of this feature is recorded in the event log.

Note: **Export restrictions** can be set without Advanced Security. Simply remove the **Export personal data** permission from staff or security groups. ## **Restricted access by IP** This feature allows staff to log in to the platform only from specific IP addresses. To enable it, provide your Mindbox manager with a list of trusted IP addresses. Once added to the platform’s web server, access to the project will be allowed only from these addresses. ## **Exporting events to SIEM (Security Information and Event Management)** This allows you to **regularly export logs** from the event log, which records: * Project logins with IP addresses * Creation, editing, and deletion of campaigns, segments, customers, and other entities * Export and import bulk tasks * Changes to staff and permissions, and more.

## **SSO — Single Sign-On** This feature lets you manage staff access centrally. Learn more about SSO [here](/security/single-sign-on-sso). ## **How to enable** The Advanced Security is enabled by default and does not require an extra fee.
