-    # This service measures usage of the Modsecurity Web Application Firewall across the entire
-    # instance's deployed environments.
-    #
-    # The default configuration is`AUTO_DEVOPS_MODSECURITY_SEC_RULE_ENGINE=DetectionOnly` so we
-    # measure non-default values via definition of either ci_variables or ci_pipeline_variables.
-    # Since both these values are encrypted, we must decrypt and count them in memory.
-    #
-    # NOTE: this service is an approximation as it does not yet take into account `environment_scope` or `ci_group_variables`.
