Forcepoint Web Security (SWG) vs Zscaler Cloud Access Security Broker (CASB): Side-by-Side Comparison (2026)

Forcepoint Web Security (SWG)

Mid-market and enterprise security teams with strict data protection requirements should prioritize Forcepoint Web Security for its integrated DLP enforcement and Shadow IT discovery, which catches both known threats and unauthorized cloud apps in a single enforcement point. The Advanced Classification Engine handles zero-day web threats without requiring constant rule updates, and Remote Browser Isolation adds a meaningful layer for high-risk users without the performance drag of older sandbox approaches. Skip this if your organization prioritizes detection and response over prevention; Forcepoint is built for teams that need to block threats before they cross the perimeter, not investigate them after.

Zscaler Cloud Access Security Broker (CASB)

Mid-market and enterprise security teams drowning in SaaS sprawl need Zscaler Cloud Access Security Broker for its inline proxy architecture that catches threats in motion without forcing users through a VPN bottleneck. The platform covers both real-time API inspection and data at rest scanning across Microsoft 365, Salesforce, and AWS, hitting NIST PR.DS and DE.CM functions hard. Skip this if your organization runs primarily on-premises applications or lacks the cloud adoption density to justify a dedicated CASB; you'll overpay for capabilities you don't need.
