Your internet service provider can also monitor your internet behavior. For example, they can view the sites you visit, the time you spend on them, the browser you're using, etc. Depending on the digital privacy laws in your region, some ISPs can go a step further and collect your IP address along with your geographical data. They can then sell this data to advertisement firms, and in turn, these farms can use it to deliver tailored ads. Sometimes ISPs can monitor how much bandwidth you're using and decide to throttle you. Bandwidth throttling means the ISP lowers your internet speed so their servers aren't overwhelmed during peak hours. The best way to prevent your ISP from monitoring your internet behavior is by using a secure VPN or a private search engine.
