Which proprietary technology does Zscaler use to calculate risk attributes dynamically for websites?

Zscaler PageRisk is a proprietary dynamic threat assessment technology embedded in Zscaler Internet Access (ZIA). PageRisk dynamically computes a real-time risk score (ranging from 1 to 100) for web pages as users navigate to them. It calculates risk attributes dynamically by analyzing page components, domain age, structural characteristics, suspicious obfuscated JavaScript, external references, and threat signals on the page. By assigning a dynamic PageRisk score, Zscaler allows administrators to enforce granular access policies, enforce browser isolation, or block access to web pages exhibiting high-risk characteristics before actual malicious payloads execute.

A. Third-Party Sandbox sends suspicious files to external sandboxing environments rather than calculating dynamic web page risk scores inline.

C. Browser Isolation Feedback Form is not a threat calculation technology; it relates to user interface feedback during isolation sessions.

D. Deception Controller manages decoys and lures for internal network threat detection, not dynamic website PageRisk scoring.
