DLP Policy Contextual Attributes Rule Not Working

Issue/Introduction

A DLP Policy Contextual Attributes Rule configured for a custom application name attribute (e.g., gatelet.chatgpt) is failing to match and is not working as expected.

Environment

DLP Release: 16.x, 25.x

Cause

The custom application name attribute entered in the DLP policy (e.g., gatelet.chatgpt ) contains a trailing space or other hidden non-printing characters.

This trailing space prevents the value in the policy from being an exact match for the actual gatelet name in the environment, causing the rule to fail.

Resolution

To fix this issue, you must ensure the custom gatelet name in the DLP policy is an exact match to the application name, with no trailing spaces or hidden non-printing characters at the end of the name.

Carefully remove any spaces at the end of the custom application name attribute (e.g., changing gatelet.chatgpt  to gatelet.chatgpt).
