Prevent tracking and fingerprinting in embedded content
Embedding third-party content—like articles, product previews, or external documents—inside your web application or email client sounds simple. But it introduces a serious privacy risk.
External sites can fingerprint users, drop tracking cookies, and associate browsing behavior with email identities or internal user sessions.
Webfuse eliminates this risk by opening each external session in an isolated, disposable browser environment that can't be tracked or reused.
External embeds open the door to tracking
When users click on external links inside email clients or portals, they are unknowingly exposed to:
- Third-party cookies and trackers
- Device fingerprinting scripts
- Cross-session identity correlation
This undermines user privacy, leaks behavioral data, and violates Zero Trust security principles.
How Webfuse solves this
Webfuse introduces Randomized Domain Mapping—a privacy-first technique that spins up unique virtual domains for every session, fully isolated from past or future visits.
Here’s how it works:
- Create a Webfuse SPACE for external content embedding.
- Enable Randomized Domain Mapping in SPACE settings.
- Use the Magic Links API to generate a secure session link.
- Embed the Magic Link into your email client or internal application.
Every user who clicks the link receives a fresh, trackless browser session in a virtual tab. Cookies, local storage, and cache are discarded at the end of each session.
Optionally, you can add the Lockdown APP to further prevent JS fingerprinting, block trackers, or enforce stricter sandboxing.
Key Benefits
- No Tracking Persistence: Cookies, storage, and identifiers are cleared per session.
- True Anonymous Browsing: Each user appears as a new, unrelated visitor.
- Blocks Fingerprinting: Unique domain + sandboxed session stops device profiling.
- Safe Embeds for Email Clients: Display content from untrusted sources securely.
- Lockdown APP Support: Fine-grained controls to block scripts, cookies, and more.
Examples
- Email clients embedding external articles or newsletters
- CRMs embedding third-party analytics links
- Internal tools previewing external PDFs or product URLs
- Messaging platforms that display clickable external previews

FAQ
Can users still interact with the embedded content?
Yes, users have full native interaction. The difference is: the content runs in a virtual tab with no persistent context.
Is this GDPR compliant?
Yes. Webfuse does not retain cookies, identifiers, or personal data unless explicitly configured.
Does it break app functionality?
Most websites work out-of-the-box. If needed, the Lockdown APP lets you fine-tune content access and script permissions.
