Safe Browsing is built in and worth leaving on. Standard mode checks sites against Google's server-side list in real time, and Enhanced mode adds on-device AI for scams it has not seen before. PhishClean adds 27 checks of its own, including leaked keys, HTTPS downgrades and hidden iframes, and nothing about the pages you visit is sent to us.

Google details are from its Chrome help page, real-time protection post and AI scam post, checked November 2026. "Not listed" means we didn't find it there, not that Google can't do it.
Safe Browsing checks sites against Google's list in real time, and Enhanced mode adds on-device AI that Google says can catch scams it hasn't seen before. PhishClean runs its own checks on the page. If a phishing page has a login form submitting to a mismatched domain, PhishClean can flag it on the first visit, even if nobody has reported it. A page showing none of its warning signs gets through.
In Standard mode, Safe Browsing sends hash prefixes to Google, plus full URLs and bits of page content if a site looks suspicious. Enhanced mode sends more. PhishClean sends us nothing about the pages you visit. Its paid leaked-password check sends 5 characters of a password hash to Have I Been Pwned, and its paid repo check asks the code host about a repository you open.
Safe Browsing covers phishing, malware and other dangerous sites, and Enhanced mode adds scam and compromised-password protection. PhishClean adds checks Google doesn't list, covering leaked API keys, JWT tokens, hidden iframes, HTTPS downgrades, form data exfiltration and more.
Google's list is far larger than PhishClean's list of about 380,000 reported phishing sites, and Google has a view of the whole web that we don't. PhishClean's advantage is narrower: extra checks on the page, run on your device, with public source code.
Honestly, most users should keep Safe Browsing enabled, and turn on Enhanced mode if they are comfortable with what it sends. Add PhishClean on top if you want the extra checks and want them to run on your device.
