Authentic8 Silo Web Isolation Platform vs DefensX: Side-by-Side Comparison (2026)

Authentic8 Silo Web Isolation Platform

Security teams protecting high-risk user populations,think financial services, government, or healthcare,should use Authentic8 Silo Web Isolation Platform to execute untrusted web code remotely instead of on endpoints, eliminating browser-based compromise as an attack vector. FedRAMP authorization plus customer-managed encryption keys for logs address the compliance and data residency concerns that kill most RBI deals in regulated sectors. Skip this if your org needs isolation as a bolt-on convenience layer rather than a foundational control; Silo requires policy discipline and assumes web isolation is worth the added latency and user friction.

DefensX

MSPs protecting SMB and mid-market clients need DefensX primarily for its browser isolation that doesn't require endpoint agents, letting you secure legacy Windows systems and BYOD devices without deployment friction. The platform covers four NIST CSF 2.0 functions (Platform Security, Data Security, Identity Management, and Continuous Monitoring), which is uncommon for browser isolation tools that typically excel only at perimeter defense. Skip this if you're an enterprise buyer expecting advanced threat hunting or post-compromise investigation; DefensX prioritizes blocking over forensics and lacks the depth of a full EDR layer.
