Browser Wars, Continued: Why Everyone Is Building Their Own AI Browser

Why It Matters

Owning the AI‑enabled browser layer gives companies strategic control over enterprise data flow and user productivity, while also exposing critical security gaps that must be addressed.

Key Takeaways

• AI browsers enable autonomous task execution across SaaS apps
• Owning browsers gives control over primary enterprise access layer
• Agentic AI introduces new security risks for data exfiltration
• Traditional SASE/SSE tools cannot distinguish AI-driven traffic
• SquareX offers BDR solution to secure any browser, any device

Pulse Analysis

The browser, once a simple gateway to the web, has become the de‑facto operating system for modern enterprises. With more than 70 % of global traffic routed through Chrome and SaaS workloads increasingly accessed via web interfaces, control of the browser equates to control of the corporate data plane. The emergence of generative AI agents that can act inside the browser transforms it from a passive viewer into an autonomous workbench, prompting both incumbents and startups to launch AI‑enhanced browsers in 2025.

OpenAI’s Operator release in January 2025 marked the first true browser‑bound AI agent capable of completing multistep workflows such as booking travel or configuring cloud resources without human clicks. This capability lowers the barrier for new entrants to differentiate themselves, because an AI‑driven browsing experience can deliver value far beyond traditional speed or UI tweaks. Companies like Atlassian, Perplexity and even the Chrome team are embedding large‑language‑model copilots directly into the address bar, turning every search into a conversational command center and reshaping user expectations for what a browser should do.

The flip side is security. Autonomous agents inherit the same privileges as the logged‑in user, allowing them to read emails, download files and invoke internal APIs, which makes them attractive vectors for data exfiltration and malware deployment. Existing SASE and SSE platforms struggle to differentiate human‑initiated traffic from AI‑generated actions, creating a blind spot in zero‑trust architectures. Vendors such as SquareX are responding with Browser Detection and Response (BDR) technology that monitors agentic behavior, enforces policy at the browser layer, and isolates rogue extensions, offering enterprises a way to secure any browser without sacrificing user experience.
