What your internet provider can see when you browse

Your internet service provider, or ISP, acts as the middleman between your devices and the internet. Every website you visit and every online service you use passes through its network.

If you are not using a VPN, your ISP can generally see which websites you are connecting to, when you are online, how much data you are using and your approximate location based on your IP address. Encrypted websites, which begin with "https://," help prevent your provider from reading the contents of most web pages or messages. However, your ISP can still often see that you connected to a certain website in the first place. That information alone can reveal a lot about your interests, routines and habits.

What websites can learn from your visit

Even if you never create an account, some websites can still learn quite a bit about your visit. They can identify your IP address, estimate your location, determine what device and browser you are using and record which pages you viewed.

Why private browsing does not make you invisible

Private browsing tabs, also known as incognito mode in some browsers, can be useful. They help prevent your browser from saving your local browsing history after you close the window.

However, private browsing does not make you invisible online. Websites can still see your visit while you are on their pages. Your internet provider can still see many of the sites you connect to. If you are using a work, school or public network, the network owner may also be able to monitor certain activity.

How to reduce what others can see

You cannot eliminate online tracking entirely, but you can make it harder for companies to collect information about you. Start by reviewing your browser's privacy settings. Turn off unnecessary website permissions, such as location, microphone and camera access for sites that do not need them. Consider using a privacy-focused browser or search engine that collects less personal data.

The more details you provide across websites, apps and accounts, the easier it becomes for companies to connect your activity. Most importantly, consider using a VPN.

How a VPN helps protect your browsing activity

A VPN, or virtual private network, encrypts your internet traffic before it leaves your device. Instead of your internet provider seeing which websites you are connecting to, it sees an encrypted connection to the VPN server. That makes it much harder for your ISP to build a browsing profile based on your online activity.

A solid VPN makes this process easier by offering apps for computers, smartphones, tablets, smart TVs and routers. That allows you to protect multiple devices with one account.
