Hello Prerana Yadav and welcome to the Netwrix Community portal!
Thank you for sharing feedback on Endpoint Protector.
To start with, I would like to inform you that the Predefined Content section of Endpoint Protector already includes detection for U.S. passports. To utilize this, simply proceed to Content Aware Policies > Policy Denylists, followed by Predefined Content, and select United States under Passport section.
On the other hand, I am pleased to announce that we are in the process of updating the U.S. Passport PII pattern, and this improvement will be implemented in the forthcoming releases.
