High complexity + constant tuning
SASE Overhead- ● PAC files, routing rules & inspection tuning.
- ● Client agents break after OS updates.
- ● SSL inspection causes performance complaints.
- ● End users experience slow or blocked web apps.
Built to replace SASE tools like Zscaler
MSPs • Zero Trust Browser-Based Access
Why MSPs are switching from Zscaler to DefensX.
Zscaler is powerful, but complex and expensive especially for MSPs supporting many small and mid-size clients. Licensing, PAC file issues, routing dependencies, and user experience complaints create constant friction. DefensX delivers Zero Trust access, browser isolation, and DNS security with lower cost, zero agents, and MSP-ready multi-tenant management.

Enterprise-grade SASE creates unnecessary overhead for small & mid-size customers.
Not built for MSP multi-tenant UX
Operational Drag- ● Per-customer tuning becomes time-consuming.
- ● Multi-tenant dashboards not MSP-friendly.
