Authentic8 Silo Workspace vs Palo Alto Networks Remote Browser Isolation: Side-by-Side Comparison (2026)

Short answer

Enterprise and mid-market teams running investigations into financial crime, supply chain threats, or state-sponsored activity need Silo Workspace because its 700+ global proxy endpoints let you mask attribution while collecting forensic evidence from hostile infrastructure without exposing your own network. The managed attribution network across 32 countries plus encrypted chain-of-custody storage directly addresses NIST DE.CM and RS.AN requirements that most browsers can't touch. Skip this if your investigators work mostly on domestic, low-risk research; the tradecraft training and dark web capability are overkill for routine threat intelligence gathering. 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.
