Optimizely Content Management System

Describes GDPR guidelines for Optimizely Content Management System (CMS).

Collect data

Optimizely Content Management System (CMS) Core logs system activities such as events and system errors.



From CMS Core 11.4.0, log files do not include any Personally Identifiable Information (PII), such as usernames or IP addresses. See Write log messages for logging configuration in CMS 12.

Ask for consent for Visitor groups

Visitor groups provide a means to personalize content. You can disable visitor groups on a per-request basis to reflect brand privacy policy and consent. One option is to react to “do not track” headers but you should customized it to fit the brand privacy policy. Some of the built-in visitor groups collect data using cookies with a limited lifetime, but nothing personally identifiable is stored centrally by default, which is the recommended pattern. If you do track and store PII using customer visitor group criteria, ensure you have consent first.

Store data

See also Store data and Data guidelines.

DXP Secure data

Optimizely Digital Experience Platform (DXP) secures access to stored PII in several ways. All content stored in DXP is encrypted at rest, access to the underlying storage technologies and infrastructure is restricted to Optimizely personnel, and access to the website is secured through the included Web Application Firewall. Most vulnerabilities are usually found in the application layer, so we strongly recommend running regular scans of all sites using the optional Web Vulnerability Scanner, or similar technology of your own choosing.

CMS Secure data

CMS relies on SQL server for most of its storage needs, so you should restrict access to SQL server and use the built-in encryption capabilities to protect PII data at rest.

CMS Profiles

The built-in profile system does not track PII by default but can certainly be used that way. If you choose to store PII in the profile system, ensure the underlying storage is appropriately protected (encryption, regular vulnerability scanning, and so on) and that consent is explicitly given by users represented by the profiles.

Fetch data

CMS Profiles

The profile system provides the ability to query and update profiles.

CMS Visitor Groups

Unless you have added your own or third-party visitor group criteria, you should not have any PII collected by visitor groups, and so no data to correct or query here. Anything stored in cookies can of course be deleted by the visitor by clearing cookies.

Delete data


Data deleted from the underlying storage is deallocated and physically deleted through NIST certified methods. All deallocated data is physically deleted within at most 180 days.
