How Scammers Steal Data From Legitimate Websites
When you type your credit card number, home address, or Social Security number into what looks like a completely normal payment form, the hidden script sends a copy of your information directly to the hacker's server.
What is Data Loss Prevention (DLP)?
If a form tries to send a valid credit card number, Social Security number, or sensitive private key without your explicit permission, the DLP system flags it and prevents the leak.

Frequently Asked Questions
Does BrowserShield store my credit card numbers?
No, never. BrowserShield processes form data locally in your computer's memory during submission. It never saves, logs, or transmits your financial details anywhere.
Will BrowserShield interfere with normal online shopping?
No. BrowserShield operates seamlessly during regular checkout on verified sites, only alerting you if an unauthorized or suspicious script attempts to exfiltrate data.
