+# Security Configuration **(ULTIMATE)**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/20711) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.6.
+
+## Overview
+
+The security configuration page displays the configuration state of each of the security
+features and can be accessed through a project's sidebar nav.
+
+![Screenshot of security configuration page](../img/security_configuration_page_v12_6.png)
+
+The page uses the project's latest default branch [CI pipeline](../../../ci/pipelines.md) to determine the configuration
+state of each feature. If a job with the expected security report artifact exists in the pipeline,
+the feature is considered configured.
+
+NOTE: **Note:** if the latest pipeline used [Auto DevOps](../../../topics/autodevops/index.md),
+all security features will be configured by default.
+
+## Limitations
+
+It is not possible to enable or disable a feature using the configuration page.
+However, instructions on how to enable or disable a feature can be found through
+the links next to each feature on that page.
