# What is the difference between an ad blocker, content blocker, and Sapher Shield?

## Ad blockers hide ads, content blockers remove trackers, and Sapher Shield identifies unsafe websites in real time.  

Ad blockers are software tools designed to prevent ads from being displayed on websites, including pop-ups, banners, videos, and other types of marketing that can interrupt your browsing experience. Content blockers on the other hand, encompass a wider range of software that not only blocks ads but also other elements like tracking scripts, social media widgets, and website analytics tools that can impact page loading speed and pose privacy and security risks. 

In contrast, Sapher Shield evaluates the *safety* of websites you visit in real-time by assigning a trust rating. Utilising intelligent algorithms and a database of verification records to identify any suspicious activities on the site, Sapher Shield provides instant protection against evolving cyber threats.
