PAN Discovery Browser is a free Chrome extension developed by Sure QC that aims to protect your browser from pages containing cardholder data. This add-on allows you to prevent payment card numbers from being displayed and provides a notification if the page potentially contains such information. The detection is done within the browser, ensuring that no information is sent to any other location.

With PAN Discovery Browser, you can effectively prevent accidental forwarding of emails that may contain card numbers in online email systems. It also enables you to identify, report, and initiate incident response when unexpected credit or debit card numbers are located. This extension is particularly useful for individuals and organizations that handle sensitive cardholder data and want to ensure compliance with the PCI DSS standard.
