Glasswall ICAP vs Sasa Software GateScanner Security Dome: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams handling high-volume file traffic across email and web gateways should prioritize Glasswall ICAP for its content disarm and reconstruction engine, which removes threats without blocking legitimate files. The tool's ICAP server architecture integrates directly into existing proxy and gateway infrastructure, meaning you get real-time threat removal without ripping out your perimeter stack. Skip this if your organization relies heavily on allow-listing or has minimal file exchange friction; ICAP overhead becomes unjustifiable when your threat model doesn't center on malicious document payloads. SMB and mid-market teams handling sensitive file transfers across hybrid environments need GateScanner Security Dome for its CDR sanitization engine, which strips malware from files without requiring endpoint agents or complex infrastructure redesigns. The platform's multi-tenant architecture and portable media controls address the real compliance gap most organizations face: securing file movement across web, cloud storage, and USB channels simultaneously. Skip this if your priority is detecting advanced threats in network traffic or endpoint behavior; GateScanner focuses exclusively on file content security and storage, not lateral movement or persistence.
