NetShield(new window) works by checking the domain requests of every website and app you use against a database of domains that are known to host malware, ads, or trackers. When NetShield finds a match, our DNS server protects your device by automatically blocking the flagged resource from loading.
NetShield uses DNS filtering to block ads as well as the online trackers that advertisement companies use to follow you around the internet. This keeps your device secure and your browsing private.
NetShield prevents your device from loading unnecessary content from a website, like ads and trackers. This reduces the amount of data you need to load to visit a site, speeding up your browsing.
You can decide what NetShield blocks. Choose your level of protection by blocking only malware, blocking malware, ads, and trackers, or turning NetShield off entirely.
