TotalAV has the best phishing protection for Mac users. Its free WebShield tool is designed to block phishing sites and online malware, and it outperforms the built-in protections in Chrome and Firefox. It employs renowned blacklists of dangerous websites and uses an AI-based detection system for picking up on unknown threats. Additionally, TotalAV offers customization options allowing you to block specific URLs or whitelist domains.
Unfortunately, the tool isn’t available on Safari, but you can use the TotalAV Safe Site tool instead if you’re a Safari user. It didn’t work quite as well as WebShield in my tests, but it’s still pretty good. That said, I recommend downloading Chrome on your Mac and choosing WebShield if you haven’t already.
