OpenAI has officially entered the web-browsing market with ChatGPT Atlas, a new browser built on Chromium: the same open-source base that powers Google Chrome. At first glance, Atlas looks and feels almost identical to Chrome or Safari. The key difference is its built-in ChatGPT assistant, which allows users to interact with web pages directly. For example, you can ask ChatGPT to summarize a site, book tickets, or perform online actions automatically, all from within the browser interface. While this innovation promises faster and more efficient browsing, privacy experts are increasingly worried about how much personal data the browser collects and retains. How ChatGPT Atlas Uses “Memories” Atlas introduces a feature called “memories”, which allows the system to remember users’ activity and preferences over time. This builds on ChatGPT’s existing memory function, which stores details about users’ interests, writing styles, and previous interactions to personalize future responses. In Atlas, these memories could include which websites you visit, what products you search for, or what tasks you complete online. This helps the browser predict what you might need next, such as recalling the airline you often book with or your preferred online stores. OpenAI claims that this data collection aims to enhance user experience, not exploit it. However, this personalization comes with serious privacy implications. Once stored, these memories can gradually form a comprehensive digital profile of an individual’s habits, preferences, and online behavior. OpenAI’s Stance on Early Privacy Concerns OpenAI has stated that Atlas will not retain critical information such as government-issued IDs, banking credentials, medical or financial records, or any activity related to adult content. Users can also manage their data manually: deleting, archiving, or disabling memories entirely, and can browse in incognito mode to prevent the saving of activity. Despite these safeguards, recent findings suggest that some sensitive data may still slip through. According to The Washington Post, an investigation by a technologist at the Electronic Frontier Foundation (EFF) revealed that Atlas had unintentionally stored private information, including references to sexual and reproductive health services and even a doctor’s real name. These findings raise questions about the reliability of OpenAI’s data filters and whether user privacy is being adequately protected. Broader Implications for AI Browsers OpenAI is not alone in this race. Other companies, including Perplexity with its upcoming browser Comet, have also faced criticism for extensive data collection practices. Perplexity’s CEO openly admitted that collecting browser-level data helps the company understand user behavior beyond the AI app itself, particularly for tailoring ads and content. The rise of AI-integrated browsers marks a turning point in internet use, combining automation and personalization at an unprecedented scale. However, cybersecurity experts warn that AI agents operating within browsers hold immense control — they can take actions, make purchases, and interact with websites autonomously. This power introduces substantial risks if systems malfunction, are exploited, or process data inaccurately. What Users Can Do For those concerned about privacy, experts recommend taking proactive steps: • Opt out of the memory feature or regularly delete saved data. • Use incognito mode for sensitive browsing. • Review data-sharing and model-training permissions before enabling them. AI browsers like ChatGPT Atlas may redefine digital interaction, but they also test the boundaries of data ethics and security. As this technology evolves, maintaining user trust will depend on transparency, accountability, and strict privacy protection.

OpenAI and Perplexity are taking on Google in new Browser Wars...but if you get in now, you could be a real casualty.

After the release of a slew of other AI-integrated browsers, Anthony Enzor-DeMeo discusses ChatGPT Atlas, the Google monopoly trial – and the future

  Despite the ripples that Google has created in the global tech community, the company has announced that its long-promised privacy initiative for Chrome is being discontinued. In a move that has shocked the global tech community, Google has ended one of the most ambitious projects of its life, one in which it hoped to reinvent the world of online privacy.  In the wake of years of assurances and experiments, the company is officially announcing that the company will be phasing out its Privacy Sandbox project, once hailed as a way to eradicate invasive tracking cookies. There have been over three billion Chrome users since Chrome was launched, and many of them were expecting a safer, more private browsing experience. This decision marks a significant shift for Chrome.  In the beginning, the Privacy Sandbox was introduced with the goal of bringing about an “even more private web” while maintaining a delicate balance between user protection and the advertising industry's needs for data collection. Despite Google's six-year plan, which was criticised by regulators and encountered numerous technical difficulties, the company has admitted that the program failed to provide a viable alternative to third-party cookies. This news is in response to recent warnings from Apple and Microsoft regarding Google Chrome, both of which cautioned against relying on the application due to concerns regarding privacy and security. Google's vision of a privacy-first web seems to have faltered in light of this latest development — leaving many users and industry observers wondering what is going to happen to online tracking, digital advertising, and the world's most popular browser in the next five years. In the year 2024, Google embarked upon a transformative endeavour, redefining digital advertising and user privacy for the next generation of users.  A tech giant operated by Alphabet, under its parent company, announced plans to phase out third-party cookies from Chrome - a cornerstone of online tracking for decades - and replace them with an improved Privacy Sandbox framework. Specifically, this initiative was created to understand user preferences without the invasive cross-site tracking that has long fueled personalised advertising campaigns.  Among Google's objectives was twofold: to ensure privacy standards and maintain the profitable precision of targeted ads, which drive substantial revenue for the company. The Privacy Sandbox, which was launched in 2019, was a major architectural change in the way online ads were delivered. Instead of being reliant on external tracking servers for data processing and ad selection, users' browsers and devices were responsible for processing data and displaying ads. 3The project, however, despite years of testing and global scrutiny, did not produce a viable alternative to third-party cookies, which was the reason Google eventually decided to cease its six-year experiment by formally discontinuing the Privacy Sandbox earlier this year. As a quiet acknowledgement of the difficulty of balancing privacy and profits, the company officially ceased the experiment earlier this year.  Despite the prospect of extensive tracking and customised ad targeting once again facing Chrome users, the browser's dominance over the global market does not appear to be declining. Chrome still holds more than 70 per cent of the browser market share across both mobile and desktop platforms, making it the leading browsing tool in the world.  Even so, Google's leadership understands the shifting currents in the industry. With the advent of emerging AI-enabled browsers, such as Perplexity's Comet and an anticipated release from OpenAI, users are beginning to redefine what their online experience should be, as people move towards a more social and mobile experience.  A critical inflexion point has been reached when Google decided to discontinue the Privacy Sandbox, which has been at the forefront of the ongoing debate around privacy and data-driven advertising since the 1990s. As a method of replacing third-party cookies with more privacy-conscious alternatives, the project was introduced with the intention of enabling advertisers to gain insight into users' interests without invasive cross-site tracking.  Having launched in 2019, the initiative is intended to make sure that user privacy expectations are balanced with the commercial imperatives of the advertising industry and the scrutiny of global regulators. Google confirmed that, on October 21, the Privacy Sandbox project will be phased out, ending one of the most ambitious privacy initiatives Google has ever undertaken, after years of trials, delays, and regulatory engagement.  There was an apparent lack of industry adoption, as well as unresolved technical difficulties, that led to the discontinuation of several key components, including Federated Learning of Cohorts (FLoC), Attribution Reporting API, IP Protection, and Private Aggregation, for which the company cited limited industry adoption and unresolved technical concerns.  Despite being in favour of third-party cookies, the decision effectively preserves them for the foreseeable future in an acknowledgement that the industry does not yet have an alternative that is safe, effective, and scalable. There was a strong role played by regulatory bodies like the UK's Competition and Markets Authority (CMA) and Information Commissioner's Office (ICO) in facilitating this outcome, by highlighting potential anticompetitive risks and urging a deeper examination of the technology's ramifications.  In contrast to the CMA's request for additional time to review industry results, the ICO expressed disappointment but encouraged continued innovation towards privacy-first solutions in an attempt to combat the anticompetitive risks. There appears to be a deeper tension between privacy concerns and business imperatives, underlying this policy reversal. Privacy Sandbox had long been criticised by advertisers because of its lack of support for real-time campaign reporting and essential brand safety mechanisms.  In the future, Google plans to provide users with greater control over how their data is handled rather than completely removing cookies—a compromise reflected in both the commercial and regulatory environments in which it operates. Marketers should be aware of the implications of this persistent usage of third-party cookies.  While traditional tracking methods remain viable, the digital landscape continues to shift towards transparency and consent-based engagement in order to maintain customer relevance. Over half of marketers have already started testing cookie-free solutions as a response to upcoming restrictions, even though many still heavily rely on third-party data for their campaign execution in preparation for future restrictions.  Businesses whose companies proactively adapt - by acquiring first-party data, engaging in contextual advertising, and using privacy-safe analytics - see tangible benefits. These include improvements in performance ranging from 10 per cent for large companies to 100 per cent for smaller firms. In the long run, the move challenges businesses to evolve their marketing ecosystems to keep up with the changing market.  As a result of newsletters, loyalty programs, and interactive experiences, it is becoming increasingly important to develop first-party data strategies. Consent management systems have become increasingly popular to ensure transparency, compliance with regulations, and first-party data protection, in addition to ensuring regulatory compliance.  In recent years, contextual targeting, universal IDs, and data cleaning rooms have become increasingly popular as tools to keep campaigns accurate without losing users' trust. Despite the fact that third-party cookies will always be part of the web's fabric for a while, the industry consensus is clear: the future of digital marketing lies in developing meaningful user relationships that are built upon consent, credibility, and respect for privacy.  The next chapter of digital advertising will continue to be defined by the balance between personalisation and privacy, especially as AI-driven browsers such as Perplexity's Comet and OpenAI's upcoming offerings introduce new paradigms in user interaction. A wave of reactions has erupted across the technology and advertising industries since Google announced its decision to discontinue its privacy sandbox program, which reveals both frustration and resignation at the same time.  The decision has been described by observers as a defining moment for digital privacy and online advertising in history. A recent report from PPC Land stated that Chrome kills most Privacy Sandbox technologies after adoption fails. The report also noted that nine of Google’s proposed APIs had been retired after years of limited adoption and widespread criticism.  In an even more direct statement, Engadget declared that “Google has killed Privacy Sandbox.” According to media outlets, the company has come to a halt with its multi-year effort to reimagine web privacy after a multi-year effort. Despite these developments, Chrome's overwhelming dominance in the browser market has not been affected at all by them. Despite repeated controversies surrounding user tracking, Chrome still holds a dominant position on both the desktop and mobile markets.  Although privacy concerns and regulatory scrutiny have been raised, its cookie-replacement initiative failed to deliver a meaningful impact on user loyalty. The reality is that in the coming years, emerging competition from AI-powered browsers such as Perplexity's Comet and an upcoming browser from OpenAI could eventually reshape this landscape.  In response to this, Google has been accelerating its innovation within Chrome, integrating its Gemini artificial intelligence system to enhance browsing efficiency as well as counter rising rivalry. Several people have already criticised Gemini for its deeper integration of data, suggesting that instead of reducing user tracking, this deeper integration may actually result in a greater amount of tracking of users. This paradox highlights the complexity of the relationship between Google and privacy once again.  A recent article from Gizmodo notes that Google has completely removed the Privacy Sandbox, so it appears the long-deferred plan has come to a halt somewhere along the way. Throughout the publication, it was mentioned that individualised user tracking was an integral part of the modern advertising-supported web, and even though the debate has lasted for many years, it still remains in place.  A major reason for the enduring tension between Google and its users is that the company is simultaneously responsible for ensuring user privacy while also making an important contribution to the creation of the highly data-driven advertising ecosystem that the company is continuing to benefit from to this very day.  It was widely feared that Google's elimination of cookies would only strengthen its competitive position, since it has unique control over both data and advertising infrastructure. This situation was described as a temporary pause rather than a permanent resolution by Search Engine Land. As a result of Google's retreat, the cookie chaos has been brought to an end for now, but it is unclear whether privacy-first advertising will last in the future. There was a strong emphasis placed on the fact that the Privacy Sandbox was Google’s response to mounting privacy regulations and a backlash against cross-site tracking, but due to its complexity, slow adoption, and regulatory restrictions, it failed to achieve its full potential. Although the industry may find some relief in the short term by maintaining familiar advertising tools, there remain long-term challenges to overcome.  Forbes noted that the discontinuation may bring some stability today, but more uncertainty tomorrow. Advertisers will continue to rely on tracking models as regulatory pressures tighten around the world. Almost six years after Google first promised to end third-party tracking, the web has remained much the same: users are still being monitored across many sites, and the promise of a truly privacy-protected digital experience has yet to come true.  Currently, the industry finds itself in a difficult position - balancing the necessity of commercial growth with ethical responsibilities - as the next generation of AI-powered browsers threatens to upset the ecosystem once again with its ongoing disruptions. With Google's withdrawal of its once-celebrated Privacy Sandbox coming to a close, the digital ecosystem stands at a crossroads between convenience and conscience as it marks the end of a six-year experiment.  The decision of the company highlights what remains to be an uncomfortable truth about the internet's economic engine: individual data trails still play a major role in its economic engine. Although the advertising industry is facing a turning point, it is an opportunity for businesses and advertisers to rethink their engagement strategies. The future lies in transparent and consent-driven marketing that creates meaningful value exchanges based on trust, consent, and meaningful transparency.  Brands that proactively invest in first-party data ecosystems, privacy-friendly analytics, and contextual intelligence will not just ensure compliance but will also strengthen customer loyalty in the process. Throughout this evolution, regulators, developers, and marketers need to collaborate to design frameworks that respect privacy without stifling innovation, as the rise of artificial intelligence browsers and an increased awareness of the importance of privacy will make it more than a regulatory checkbox, but instead one of the defining features of a brand.  Those who adapt early to the new digital transformation paradigm, incorporating ethical principles into their strategy from the beginning, will emerge as trusted leaders in the next chapter of digital transformation - where privacy is no longer an obstacle to be overcome, but a competitive advantage contributing greatly to the future success of the web.

Here's something that should make you pause before hitting that "Enable AI Agent" button: the same AI browsers promising to revolutionize how you interact with the web might also be opening the door to an entirely new category of cyberattacks. And here's what makes this scary: traditional security measures won't stop them. Let me break down what's really happening with agentic browsers and why cybersecurity experts are sounding alarm bells across the industry.

There are a lot of 'what ifs' surrounding AI browsers right now

The attack we developed shows that traditional Web security assumptions don't hold for agentic AI, and that we need new security and privacy architectures for agentic browsing.
