TL;DR: Browser security is now a top-five priority for 88% of organizations and 26% rank it first, while 86% have increased spending, according to Omdia's 2026 research, because the browser has become the place where identity, data, and AI risk converge. The market is splitting between extensions, enterprise browsers, and remote browser isolation, and the governance question is which control layer matches the threat model.

By the numbers:

Questions worth separating out

Q: How should security teams choose between a full-stack browser and a browser extension?

A: Choose based on the control outcome, not feature lists.

Q: Why do browser-based attacks matter to IAM and identity governance teams?

A: Browser-based attacks matter because the browser is where users authenticate, work, and move data in the same session.

Q: What should organisations evaluate before buying remote browser isolation?

A: They should test whether the threat they care about is content execution on the endpoint or session abuse in the browser.

Practitioner guidance

  • Map browser controls to specific identity outcomes Separate browser telemetry for phishing detection, AI governance, DLP, and contractor session control.
  • Instrument the browser as an identity signal source Feed browser events into IAM, SIEM, and insider-risk workflows so token theft, OAuth consent, and shadow AI usage are visible alongside authentication and access logs.
  • Test session-based attack coverage, not just URL blocking Validate whether the control detects AiTM phishing, ClickFix, malicious OAuth consent, and token reuse when the infrastructure rotates quickly.

  • Specific detection examples for AiTM phishing, ClickFix, token theft, and OAuth consent abuse
  • Customer deployment notes on managed and unmanaged devices, including rollout friction and browser coverage

Browser security is now an identity governance problem, not just a web security problem. The browser is where users authenticate, grant consent, launch SaaS sessions, and increasingly interact with AI tools. That makes browser-layer telemetry relevant to IAM, NHI governance, and insider-risk workflows at the same time. Security teams that still treat the browser as an edge device are missing the actual control surface where identity is exercised.

A few things that frame the scale:

  • 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
  • A separate finding from our research shows that only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, highlighting a confidence gap that browser-layer identity telemetry helps expose.

A question worth separating out:

Q: How should security teams govern Shadow AI in everyday browser use?

A: Security teams should govern Shadow AI by enforcing controls where users actually interact with AI tools, not only at the network edge. That means browser-level inspection, content classification, and policy enforcement for paste, upload, and prompt actions. If users can move sensitive data into an AI tool without a control decision, the governance model is incomplete.
