Do Browsers Protect You from Fast-Moving Phishing Sites?

The number of active phishing URLs globally has exploded this past year, passing 10 million last month, up 172% from the number at the beginning of 2016. And they are increasingly dynamic – 20% of these disappear within two hours, and half are gone within 24 hours. Is the browser phishing protection offered by Chrome and others able to keep up with these fast-moving phishing sites? Cyren’s security lab tackled that question in a head-to-head comparison of the speed of phishing detection of four leading browsers, benchmarked against the detection speed of Cyren’s massive GlobalView™ security cloud for extra measure.

The upshot? The best performing browser – Chrome – still missed 26% of these malicious URLs during a 48-hour test, and lagged Cyren by an average of 6 hours in detection (and protection). And the worst – Internet Explorer – didn’t provide a browser warning for 78% of the phishing sites, and was on average 9 hours (and 6 minutes) slower than Chrome, and lagged Cyren by 15 hours, 29 minutes…. So, the answer is no – built-in browser protection will not adequately protect your users from today’s dynamic phishing sites.
