…Stay secure with upgrades to Safe Browsing
Google Safe Browsing in Chrome automatically protects you by flagging dangerous sites and files. Previously, it worked by checking every site visit against a locally-stored list of known bad sites, which is updated every 30 to 60 minutes. But phishing domains have gotten more sophisticated — and today, 60% of them exist for less than 10 minutes, making them difficult to block.
To block these dangerous sites the moment they launch, we’re upgrading the Standard protection mode of Safe Browsing so it will now check sites against Google’s known-bad sites in real time, without sharing your browsing history with Google. By shortening the time between identification and prevention of threats, we expect to see 25% improved protection from malware and phishing threats. This update will roll out to Chrome in the coming weeks.
If you want even more protection, you can always turn on Safe Browsing’s Enhanced Protection mode, which continues to block new attacks with AI, provide deep scan for files, and offer extra protection from malicious Chrome extensions…
