Privacy and security aren’t just something you should hope for — they’re something you should expect. That’s why features to help protect your privacy and keep your Mac secure are built into Safari.

Intelligent Tracking Prevention. Remember when you looked at that green mountain bike online? And then saw annoying green mountain bike ads everywhere you browsed? Safari uses machine learning to identify advertisers and others who track your online behavior, and removes the cross‑site tracking data they leave behind. So your browsing stays your business. And Safari keeps embedded content such as Like buttons, Share buttons, and comment widgets from tracking you without your permission. We know you’ll like that.

Sandboxing. Built-in protection for websites. Sandboxing provides a safeguard against malicious code and malware by restricting what websites can do. And because Safari runs web pages in separate processes, any harmful code you come across in one page is confined to a single browser tab, so it can’t crash the whole browser or access your data.

Fingerprinting defense. When you’re online, the characteristics of your device can be used by advertisers to create a “fingerprint” to follow you. Safari thwarts this by only sharing a simplified system profile, making it more difficult for data companies to identify and track you.

Protection from harmful sites. Safari helps protect you against fraudulent websites and those that harbor malware — before you visit them. If a website looks suspicious, Safari prevents it from loading and warns you.

Private Browsing. When you use Private Browsing, Safari doesn’t remember the pages you visit, your search history, or your AutoFill information. You can also use DuckDuckGo, a built-in search engine that doesn’t track you, to make your web searches private, too.
