On the latest version of Sarafi 3.2 you will get alerts “when you’re visiting a fraudulent websites”. By default it will be enabled but if you like, you can disable this security alerts from security tab which is showed in zdnet.

Also zdnet’s Rayan says, “The feature, turned on by default in Safari 3.2, displays a warning page when Safari users surf to a fraudulent Web site.  It is powered by Google’s blacklist of fake Web sites that are used to steal user credentials for banking and other finance-related Web sites.”

Also the Internet Explorer 8, Mozilla, Opera browsers already have anti-phishing  protection but lastly Safari enabled this major security alerts which is so important for any users.
