Zero Trust Browsing: Why Traditional Perimeters Are Dead
Legacy “castle-and-moat” security assumes anything inside the perimeter can be trusted. Today, employees, applications, and data live outside that perimeter—and attackers do too. The result: trust becomes the easiest thing to exploit.
Zero Trust Browsing applies the “never trust, always verify” principle to the web. Instead of executing web code on your endpoint, it runs in an isolated environment and streams only safe pixels back to the user. Phishing, malware, and zero-days are neutralized by design.
Why Traditional Perimeters Fail
- SaaS-first world: Browsing and app usage happen outside the LAN.
- BYOD & remote work: Unmanaged devices increase risk and variability.
- Threat sophistication: Phishing and exploit kits bypass detection.
- Implicit trust: Once inside, lateral movement is easy.
“Assume breach and minimize blast radius. Zero Trust makes compromise a contained event, not a catastrophe.”
What Zero Trust Browsing Means
Every site is treated as untrusted. Web sessions run in disposable, isolated containers—remote or on-prem—so malicious code never touches endpoints. Policies control URL categories, file handling, clipboard, downloads, and data egress.
Prevention by Design
Execute untrusted web code away from users. Stream only visuals, not code.
Policy-Driven Access
Granular controls for categories, domains, downloads, copy/paste, and uploads.
How It Works
- Intercept: Requests route to the isolation service.
- Isolate: Page executes in a disposable container.
- Stream: Safe pixels and sanitized inputs flow to the user.
- Enforce: Policies govern data transfer and features.
- Destroy: Container is torn down; no persistence.
Key Benefits
Stops Malware & Zero-Days
Exploit kits and malicious scripts run remotely, not on endpoints.
True Zero Trust
Treats all sites as untrusted; continuous verification with policy.
Data Loss Prevention
Controls for file downloads, uploads, clipboard, and form exfiltration.
Reduced Attack Surface
Endpoints no longer execute arbitrary web code; risk drops sharply.
Common Use Cases
- High-risk browsing: Research, vendor portals, unknown sites.
- Remote/contractor access: Unmanaged devices with strict policies.
- Compliance-driven: GDPR, HIPAA, PCI with strong data controls.
- Phishing resilience: Email links open isolated by default.
