Garrison Technology vs Palo Alto Networks Remote Browser Isolation: Side-by-Side Comparison (2026)

Short answer

Enterprise security teams defending against supply chain attacks and zero-days need Garrison Technology's hardware-enforced browser isolation because it eliminates the attack surface entirely rather than betting on detection. The appliance-based deployment means compromised websites never touch your endpoints, and the hardened architecture aligns with NIST PR.PS by enforcing security at the platform level where software controls alone fail. Skip this if your org needs lightweight per-user solutions or deep integration with your existing DLP stack; Garrison's strength is isolation-first, which demands acceptance of its deployment model and user experience tradeoffs. Mid-market and enterprise security teams already running Prisma Access will see immediate ROI from Palo Alto Networks Remote Browser Isolation because native integration eliminates the deployment friction that kills most RBI programs. Its vector and pixel-based isolation rendering blocks zero-day web exploits without breaking dynamic applications, and the cloud-delivered model means no endpoint agents or infrastructure buildout. Skip this if you need RBI as a standalone tool divorced from your existing Palo Alto stack; the value proposition collapses when you're integrating across vendors.
