Securing Remote Workers with Browser Isolation
Hybrid and remote work expand the attack surface: unmanaged devices, home networks, shared machines, and inconsistent patch levels. Traditional network-centric controls rarely apply. Remote Browser Isolation (RBI) enforces Zero Trust for web activity by executing all sessions in hardened containers and streaming only pixels to the user.
“Treat every browsing session as untrusted. Isolation makes that practical—without slowing people down.”
Challenges in Distributed Environments
- Unmanaged endpoints: Mixed OS and patch levels heighten exposure.
- Shadow IT and SaaS sprawl: Users access unsanctioned tools and data silos.
- Phishing and credential theft: Increased email and chat reliance means more clicks.
- Data egress risk: Copy/paste, downloads, and uploads outside visibility.
RBI Core Principles
Isolation First
All active web code runs in disposable containers—nothing executes locally.
Pixel Streaming
Endpoints receive visuals only; scripts, DOM, and binaries stay remote.
Granular Policy
Control downloads, uploads, clipboard, printing, file types, and categories.
Automatic Disposal
Sessions end, containers destroyed; no persistence or lateral movement.
Workflow Example
- User requests a site—traffic routed to isolation service.
- Container spins up; site executes remotely.
- Pixels stream to endpoint; inputs relayed back securely.
- Policies evaluate actions (download, form submit, clipboard).
- Session terminated and container destroyed.
Key Benefits for Remote Teams
- Uniform protection: Same control plane regardless of device state.
- Phishing resilience: Malicious pages isolated; credential controls enforced.
- Reduced support burden: Fewer incidents from drive-by and script attacks.
- Regulatory alignment: Logging and data flow controls aid compliance.
Implementation Tips
- Start with high-risk categories (unknown, newly registered, file sharing).
- Enable credential domain allowlists.
- Sanitize or convert risky downloads (scripts, macros).
- Integrate SSO for frictionless user onboarding.
- Feed isolation telemetry into SIEM for unified visibility.
Measuring Success
- Drop in browser-originated alerts and endpoint infections.
- Policy enforcement stats (blocked downloads, prevented credential posts).
- User adoption with minimal performance complaints.
- Time to contain suspicious browsing events (near zero).
