Zscaler Browser Isolation

Zscaler Browser Isolation is a cloud-native remote browser isolation service designed to safeguard corporate endpoints and sensitive internal applications from web-borne malware, zero-day exploits, and unauthorized data leakage. By executing all active web code within isolated, disposable cloud containers within the Zscaler Zero Trust Exchange, it renders only an interactive pixel stream to the user endpoint, preventing drive-by downloads, malicious scripts, and ransomware from reaching the physical device.

The solution operates as an integrated capability of Zscaler Internet Access and Zscaler Private Access, allowing administrators to apply isolation policies transparently without installing client-side browser plugins or modifying user workflows. It connects seamlessly with enterprise identity providers, data loss prevention policies, and threat intelligence engines to evaluate site risk and enforce real-time browsing protections. Standard operational use cases include isolating uncategorized or suspicious web destinations, preventing data exfiltration by restricting copy-paste and printing functions on untrusted devices, securing third-party contractor access to internal web portals, and shielding privileged users from targeted spear-phishing attacks.

With Zscaler Browser Isolation, organizations eliminate the risk of browser-based zero-day exploitation without sacrificing end-user productivity or web functionality. Security teams gain granular control over user interactions with web content, preventing credential entry on unverified sites and blocking unauthorized file downloads. The platform reduces endpoint remediation overhead, reinforces enterprise zero-trust postures, and ensures comprehensive defense against sophisticated web-delivered cyber threats.
