TL;DR: Federal agencies are struggling to apply Zero Trust across SaaS, legacy web apps, contractor devices, and hybrid mission environments because VPNs, endpoint agents, and inspection tools add friction that slows work and encourages workarounds, according to Island. Shifting enforcement into the browser changes the control point, but it also raises the bar for identity anchoring, session governance, and data handling policy.
NHIMG editorial — based on content published by Island: How the Enterprise Browser Modernizes Federal Zero Trust Without Breaking User Experience
By the numbers:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.
- Only 5.7% of organisations have full visibility into their service accounts.
Questions worth separating out
Q: How should security teams enforce zero trust across managed and unmanaged devices?
A: They should enforce policy at the point of access, using identity, device posture, and session context together.
Q: Why do browser-based controls matter in hybrid zero trust programmes?
A: They matter because many control decisions happen after authentication, when users interact with data, not when they first sign in.
Q: What breaks when zero trust relies too heavily on VPNs and endpoint agents?
A: Friction, latency, and inconsistent coverage usually appear first, followed by user workarounds that weaken the intended control model.
Practitioner guidance
- Define browser as a policy enforcement point Map which actions must be checked inside the session, including login, clipboard use, downloads, screenshots, and data movement.
- Bind access decisions to identity and posture signals Use existing identity systems, device posture, and application sensitivity to drive browser policy.
- Prioritise last-mile controls for sensitive workflows Set explicit controls for copy/paste, file transfer, and screen capture in high-value mission workflows.

Browser-based Zero Trust is really policy execution redesign. The article is not just about user experience. It shows that many organisations are trying to force modern policy requirements through tooling built around perimeter logic, which creates lag, inconsistency, and user resistance. For identity programmes, the browser becomes meaningful only when it executes policy at the moment access is used, not when access is merely granted.
A question worth separating out:
Q: How can organisations tell whether browser identity controls are working?
A: Look for reduced use of weak login paths, faster session revocation, fewer unauthorised consent grants, and visibility into suspicious browser behaviours such as unusual redirects or script activity. If the team cannot see those signals, the control is not working at the layer where the attack occurs.
