"For the last two decades, whether you used Chrome, Edge, or Firefox, the fundamental paradigm remained the same: a passive window through which a human user viewed and interacted with the internet. That era is over. We are currently witnessing a shift that renders the old OS-centric browser debates irrelevant. The new battleground is agentic AI browsers, and for security professionals, it represents a terrifying inversion of the traditional threat landscape."
"Even today, the browser is the main interface for AI consumption; it is where most users access AI assistants such as ChatGPT or Gemini, use AI-enabled SaaS applications, and engage AI agents. AI providers were the first to recognize this, which is why we've seen a spate of new 'agentic' AI browsers being launched in recent months, and AI vendors such as OpenAI launching their own browsers."
Browsers are shifting from passive interfaces to agentic, action-capable platforms that act autonomously on users' behalf. The browser remains the primary interface for AI assistants, AI-enabled SaaS, and AI agents, driving AI vendors to develop agentic AI browsers and proprietary browser offerings. The new generation funnels users into AI ecosystems rather than simply routing traffic to search engines or suites. The transition from read-only summarization to read-write action fundamentally changes the threat model. Agentic browsers can take actions, increasing the attack surface and inverting traditional security assumptions. Security teams must reassess controls, detection, and governance to address autonomous browser-driven risks.
