ChatGPT Atlas Rated Lowest for Privacy Among Browsers in 2025

A recent report from Digitain has revealed that ChatGPT Atlas ranks as the least secure browser for privacy in 2025. The analysis examined 13 popular web browsers, assessing their effectiveness in preventing user tracking and ensuring data protection. ChatGPT Atlas failed all state partitioning tests, indicating it cannot stop websites from tracking users across different sessions, and it garnered a mere 1 point in anti-fingerprinting protection.

The study employed a detailed methodology, evaluating each browser on three critical dimensions: the ease with which websites can track or identify users, the effectiveness in blocking data collection through cookies and trackers, and the security of connections between websites. Each category contributed to a final Privacy Risk Score, which ranged from 1 to 99, with higher scores indicating poorer privacy protection.

Privacy Risk Scores of Major Browsers

The findings indicate that Chrome ranks among the least private browsers as well, scoring just 41 out of 100 in connection security. Despite its popularity, Google’s browser received 68 points for its ability to prevent websites from identifying users, but alarmingly, it scored 0 for blocking trackers. This lack of protection allows companies to monitor user activity freely across the web.

Here is a summary of the ten browsers with the highest privacy risks:

– **ChatGPT Atlas**: Privacy Risk Score 100, Anti-Fingerprinting Score 1, Tracker Blocking Score 0, Connection Security Score 24
– **Chrome**: Privacy Risk Score 76, Anti-Fingerprinting Score 68, Tracker Blocking Score 0, Connection Security Score 41
– **Vivaldi**: Privacy Risk Score 75, Anti-Fingerprinting Score 68, Tracker Blocking Score 0, Connection Security Score 37
– **Edge**: Privacy Risk Score 63, Anti-Fingerprinting Score 68, Tracker Blocking Score 15, Connection Security Score 41
– **Opera**: Privacy Risk Score 58, Anti-Fingerprinting Score 68, Tracker Blocking Score 25, Connection Security Score 41
– **Ungoogled**: Privacy Risk Score 55, Anti-Fingerprinting Score 71, Tracker Blocking Score 25, Connection Security Score 41
– **Firefox**: Privacy Risk Score 50, Anti-Fingerprinting Score 74, Tracker Blocking Score 25, Connection Security Score 47
– **Safari**: Privacy Risk Score 49, Anti-Fingerprinting Score 80, Tracker Blocking Score 25, Connection Security Score 47
– **DuckDuckGo**: Privacy Risk Score 44, Anti-Fingerprinting Score 58, Tracker Blocking Score 79, Connection Security Score 51
– **Tor**: Privacy Risk Score 40, Anti-Fingerprinting Score 52, Tracker Blocking Score 70, Connection Security Score 83

ChatGPT Atlas, launched by OpenAI, not only failed in blocking trackers but also did not offer any protection against data collection via cookies or query parameters. The browser’s overall performance in basic security measures was notably poor, with a connection and navigation security score of only 24 out of 100.

Following ChatGPT Atlas, Vivaldi also underperformed in privacy measures, achieving the same anti-fingerprinting score as Chrome but failing to block any trackers. Microsoft Edge, while slightly better with a tracker blocking score of 15, still did not provide sufficient protection against data collection.

Concerns Over AI-Powered Browsers

The report raises significant concerns over the growing use of AI-powered browsers like ChatGPT Atlas. As these tools leverage data to enhance user experience, they may inadvertently gather more personal information than users realize. This potential for increased data collection adds another layer of complexity to privacy discussions.

While many users may be drawn to these advanced browsers for their features, the findings from Digitain serve as a stark reminder of the importance of privacy in the digital age. Users are encouraged to consider these privacy risk scores when choosing their browsers, especially if they are concerned about data security and online tracking.

The implications of these findings are clear: as web browsing continues to evolve, prioritizing privacy will be essential for users worldwide.
