PhishGuard is a free service that detects and rapidly disables Internet "phishing" or "spoofing" attacks designed to steal critical financial data. PhishGuard works with all popular browsers on Microsoft Windows computers. The first person to discover a suspected phishing scam can report the offending email or URL (website address), literally in seconds. There is no need to divulge any confidential information to the scammers. Within minutes, our monitoring team has verified the scam, and added it to the ScamBase™ database. Updates to the database are rapidly distributed to every participating computer, effectively immunizing them against the newly discovered scam.

The PhishGuard system utilizes the collective observations of Internet users plus a rapid server-based submission and distribution system. This unique architecture dramatically reduces the chance that any phishing scam can “slip through the cracks” and blindside an unsuspecting Internet user.
