Internet Privacy

Internet privacy refers to the protection of user data and activity across digital networks. Users encounter multiple layers of potential data collection and surveillance, ranging from Internet Service Providers (ISPs) monitoring network traffic to websites tracking browsing behavior through cookies and similar technologies. ISPs occupy a particularly sensitive position in this ecosystem, as they can observe the destinations users visit and patterns of communication at the network level—information they may log, retain, or sell to third parties. This visibility exists because ISPs control the infrastructure through which all user traffic passes.

Common Privacy Threats

Beyond ISP-level surveillance, users face tracking from websites, advertisers, and data brokers. Cookies and similar tracking mechanisms allow sites to build profiles of browsing habits and preferences. Mobile applications often collect location data and device identifiers. Search engines and social media platforms aggregate detailed behavioral information. These various collection methods operate independently, creating fragmented but comprehensive surveillance across digital activities.

Privacy Protection Tools

Several technologies and practices can mitigate internet privacy risks. Virtual Private Networks (VPNs) encrypt traffic and route it through external servers, obscuring a user’s IP address and browsing activity from their ISP. Encrypted DNS services like DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) prevent ISPs and network administrators from seeing which websites a user attempts to visit. Browser privacy features, including tracker blocking and cookie management, offer additional protection against website-level tracking. However, these tools vary in effectiveness and may introduce their own trust considerations, as users must rely on the providers of these services.
