The browser has become the main interface to GenAI for most enterprises: from web-based LLMs and copilots, to GenAI‑powered extensions and agentic browsers like ChatGPT Atlas . Employees are leveraging the power of GenAI to draft emails, summarize documents, work on code, and analyze data, often by copying/pasting sensitive information directly into prompts or uploading files.  Traditional security controls were not designed to understand this new prompt‑driven interaction pattern, leaving a critical blind spot where risk is highest. Security teams are simultaneously under pressure to enable more GenAI platforms because they clearly boost productivity.  Simply blocking AI is unrealistic. The more sustainable approach is to secure GenAI platforms where they are accessed by users: inside the browser session. The GenAI browser threat model The GenAI‑in‑the‑browser threat model must be approached differently from traditional web browsing due to several key factors.  Us...

The browser is the nerve center of the modern workspace. Ironically, however, the browser is also one of the least protected threat surfaces of the modern enterprise. Traditional security tools provide little protection against browser-based threats, leaving organizations exposed. Modern cybersecurity requires a new approach based on the protection of the browser itself, which offers both security and frictionless deployment.  In an upcoming live webinar ( Register here ), Or Eshed, CEO of browser security company LayerX, and Christopher Smedberg, Director of Cybersecurity at Advance Publishing, will discuss the challenges facing modern enterprise in the new hybrid-work world, the gaps found in existing security solutions, and a new approach to securing the modern enterprise workspace, which is centered on the browser. The Browser is Where Work Takes Place The browser is the key to the organization's critical assets. It connects all organizational devices, identities, and SaaS ...

According to the new Browser Security Report 2025 , security leaders are discovering that most identity, SaaS, and AI-related risks converge in a single place, the user's browser. Yet traditional controls like DLP, EDR, and SSE still operate one layer too low. What's emerging isn't just a blindspot. It's a parallel threat surface: unmanaged extensions acting like supply chain implants, GenAI tools accessed through personal accounts, sensitive data copy/pasted directly into prompt fields, and sessions that bypass SSO altogether. This article unpacks the key findings from the report and what they reveal about the shifting locus of control in enterprise security. GenAI Is Now the Top Data Exfiltration Channel The rise of GenAI in enterprise workflows has created a massive governance gap. Nearly half of employees use GenAI tools, but most do so through unmanaged accounts, outside of IT visibility. Key stats from the report: 77% of employees paste data into GenAI prompts 82% of...

As enterprises continue to shift their operations to the browser, security teams face a growing set of cyber challenges. In fact, over 80% of security incidents now originate from web applications accessed via Chrome, Edge, Firefox, and other browsers. One particularly fast-evolving adversary, Scattered Spider, has made it their mission to wreak havoc on enterprises by specifically targeting sensitive data on these browsers. Scattered Spider, also referred to as UNC3944, Octo Tempest, or Muddled Libra, has matured over the past two years through precision targeting of human identity and browser environments. This shift differentiates them from other notorious cybergangs like Lazarus Group, Fancy Bear, and REvil. If sensitive information such as your calendar, credentials, or security tokens is alive and well in browser tabs, Scattered Spider is able to acquire them.  In this article, you'll learn details about Scattered Spider's attack methods and how you can stop them in their ...

Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools.

Below, we bring key statistics from the report. Highlights from the Enterprise Browse...

Most security tools can't see what happens inside the browser, but that's where the majority of work, and risk, now lives. Security leaders deciding how to close that gap often face a choice: deploy a dedicated Enterprise Browser or add an enterprise-grade control layer to the browsers employees already use and trust. The Ultimate Battle: Enterprise Browsers vs. Enterprise Browser Extensions examines this choice across nine "rounds": adoption, data protection, BYOD, productivity, management overhead, remote access, Zero Trust alignment, supply-chain security, and future-readiness, to show where each approach excels, and where trade-offs emerge. Each round uses practical, enterprise scenarios to compare the two models, making it easier to see not just what they can do, but how they perform at scale. The Browser Is Now the Workspace The browser has become the primary workspace for enterprise users. It is where sensitive data is created, accessed, and moved through copy/paste action...

Security Service Edge (SSE) platforms have become the go-to architecture for securing hybrid work and SaaS access. They promise centralized enforcement, simplified connectivity, and consistent policy control across users and devices. But there's a problem: they stop short of where the most sensitive user activity actually happens—the browser. This isn't a small omission. It's a structural limitation. And it's leaving organizations exposed in the one place they can't afford to be: the last mile of user interaction. A new report Reevaluating SSEs: A Technical Gap Analysis of Last-Mile Protection analyzing gaps in SSE implementations reveals where current architectures fall short—and why many organizations are reevaluating how they protect user interactions inside the browser. The findings point to a fundamental visibility challenge at the point of user action. SSEs deliver value for what they're designed to do—enforce network-level policies and route traffic securely between en...

SaaS applications are dominating the corporate landscape. Their increased use enables organizations to push the boundaries of technology and business. At the same time, these applications also pose a new security risk that security leaders need to address, since the existing security stack does not enable complete control or comprehensive monitoring of their usage. LayerX has recently released a new guide, " Let There Be Light: Eliminating the Risk of Shadow SaaS " for security and IT teams, which addresses this gap. The guide explains the challenges of shadow SaaS, i.e., the use of unauthorized SaaS apps for work purposes, and suggests practices and controls that can mitigate them. The guide also compares various security controls that attempt to address this risk (CASB, SASE, Secure Browser Extension) and explains how each one operates and its efficacy. Consequently, the guide is a must-read for all security leaders at...

Generative AI platforms like ChatGPT, Gemini, Copilot, and Claude are increasingly common in organizations. While these solutions improve efficiency across tasks, they also present new data leak prevention for generative AI challenges.
