The security and privacy of internet users' data have become one of the most pressing issues in the modern era. Research in this area reveals the data collection and tracking capabilities of the browsers used, urging users to be more vigilant about protecting their information.
Redaksiya reports that according to a study conducted by the Digitain team in December 2025, ChatGPT Atlas, presented by OpenAI, has been identified as the most dangerous web browser in terms of user data protection. Researchers evaluated browsers based on three main criteria: privacy protection and anti-fingerprinting defense, effective blocking of trackers and data collection, and connection/navigation security. The higher the scores collected, the higher the risk to user privacy.
ChatGPT Atlas was introduced by OpenAI at the end of October. Its main feature is its built-in chatbot and agent functionalities, capable of performing many tasks on its own. Currently available only for macOS, Windows, iOS, and Android versions of this browser will be released later. The study's authors emphasize that while new AI-based browsers like ChatGPT Atlas may have interesting features, they can collect more personal data than they appear. As much data as possible is needed to train artificial intelligence.
According to the study, Google Chrome was rated as the second most dangerous browser after ChatGPT Atlas. As of the end of 2025, Google Chrome's share of the browser market has increased to 78%. This is the highest popularity indicator in Chrome's entire history. For comparison, Microsoft Edge, which ranks second, has a share of only 10%.
Brave and Mullvad Browser have been named the best applications for privacy protection. The latter is presented as an open-source browser focused on privacy and minimizing tracking. Earlier, UNIAN provided information on how to bring back uBlock and other ad blockers to Chrome. It is also possible that some of your favorite extensions will not work tomorrow. While new AI-based browsers may have interesting features, they can collect more personal data than they appear.
