The ability to warn potential victims that they are about to stray onto a malicious website puts web browsers in a unique position to combat malware. Websites that trick (socially engineer) users to download malware have short lifespans, so it is essential that the site is discovered and added to the reputation system as quickly as possible. A good reputation system must be both accurate and fast to realize high catch rates. 

Phishing attacks pose a significant risk to individuals and organizations by threatening to compromise or acquire sensitive personal and corporate information. Email, instant messages, SMS messages and links (URLs) on social networking sites are all vectors for phishing attacks.  A browser’s ability to block malicious URLs was measured every six hours to determine how long it would take a vendor to add protection.

Phishing doubled in 2020 and so far, is up year over year,” said Vikram Phatak, CEO of “Now, more than ever, consumers should not override the warnings offered by their web browser.”
