Secure Legacy Application Access

Add Governance Around Legacy Windows Applications

Many legacy Windows applications lack modern audit, policy, and data-exfiltration controls. WebStream wraps these applications in a governed browser delivery layer.

Governed access in action

Browser access with file upload/download, print/PDF, and session behaviour governed by policy.

Full WebStream demo — governed browser access to legacy Windows applications.

How It Works

How WebStream delivers apps to the browser

The application runs on Windows you control; only its interface streams to the browser, so the host stays off the open network.

Browser-native streaming

The application UI streams to any modern HTML5 browser over TLS. There is nothing to install on the endpoint — no plug-in, agent, or extension.

No exposed RDP or VPN

Users never touch RDP port 3389 or a VPN client. Access is identity-gated through WebStream, shrinking the attack surface on both ends.

Per-app entitlement & policy

Users launch a specific application, not a desktop. File transfer, clipboard, and print/PDF are governed by policy, with a full audit trail per session.

Runs on your infrastructure

Runs in your own cloud or data centre and is accessed entirely through the browser, so data and compute stay inside your boundary.

Governance Themes

The controls a policy wrapper adds

WebStream sits between the user and the application, enforcing policy on every interaction.

Access control

Identity-driven, per-application entitlements — users reach only what they should.

Session control

Isolation, timeouts, and session behaviour governed centrally.

File upload/download rules

Control what can move in and out of the application by policy.

Public/private workspaces

Separate private and shared workspaces with appropriate access.

Print / PDF redirection

Govern printing and PDF output without exposing the host.

Clipboard policy

Allow, restrict, or block copy/paste to control data movement.

Why It Matters

Why legacy apps need a policy wrapper

They were built before modern controls

Older Windows applications rarely have audit, entitlement, or data-movement controls of their own.

Remote access widens exposure

VPN and RDP expand the surface users can reach and leave audit gaps that fail review.

Compliance needs evidence

Regulated environments need to show who accessed what, when, and what data moved.

Use Cases

Public sector and regulated industries

Government

Case-management and administrative systems needing controlled, audited access.

Healthcare

Clinical and back-office Windows applications with sensitive data handling requirements.

Finance

Regulated workflows where data egress and access must be provably controlled.

FAQ

Common questions

How does WebStream control data exfiltration?

WebStream governs file upload and download, clipboard, and print/PDF behaviour by policy, so data movement around the application is controlled rather than open.

Is access audited?

Yes. Sessions are identity-driven and audited, giving compliance teams visibility into who accessed what and when.

Does this work for regulated and public sector use?

Yes. Reduced desktop exposure, policy controls, and audit make WebStream well suited to regulated industries and public sector access requirements.

Do we need to change the application?

No. WebStream wraps your existing Windows application in a governed browser delivery layer without modifying the application.
