Your security stack can't see inside the browser.
Forrester's 2026 research reveals why the browser has become attackers' preferred entry point, and what security and IT leaders need to do about it.
Key findings
72% of information workers who use a computer for work purposes can do most or all of their work inside a browser, making it the de facto enterprise endpoint
Firewalls, SWGs, and SASE tools have no visibility into browser sessions themselves, only what's passing over the network
Unmanaged extensions can read page content, extract credentials, and exfiltrate data to third parties without triggering traditional security controls
GenAI has introduced a new class of browser-based data exposure, and blocking AI tools outright only drives shadow IT
81% of security decision-makers say they're adopting browser security solutions, but most are relying on network-layer tools that miss what's happening inside the browser itself
What you’ll learn
Forrester lays out why the browser can no longer be treated as an afterthought in your endpoint security strategy. You'll come away understanding how attackers are exploiting browser-layer gaps your current stack wasn't built to see, what best practices security and IT teams should implement now, and how enterprise browsers and browser security tools compare as a path forward.
