+# Redact Sensitive Information
+
+When users create an incident or HR case via the self-service portal, they may occasionally enter sensitive information (e.g., personal identifiers, account numbers). 
+To prevent misuse of such data, **fulfillers** can redact sensitive information from the short description or description fields.
+
+This ensures that confidential information is safeguarded and not accessible for unauthorized use or distribution.
+
+## Prerequisites
+
+1. Custom Field:
+    Add a custom field to the form to hold the redacted text.
+    Example: u_redact (Redact).
+   
+2. OnSubmit Client Script:
+    Create an onsubmit client script to redact sensitive information.
+    This script will update the **short description** and **description** field with custom value as required.
+
+**Note**: Data that has been redacted cannot be recovered.
