Client updates + tunnel instability
Legacy VPN- ● Client reinstall required after OS updates.
- ● Tunnel drops and DNS conflicts across tenants.
- ● Split tunnel failures and route priority inconsistencies.
- ● Credential caching issues on shared devices.
Sophos Connect works well for basic VPN access but MSPs supporting multiple tenants struggle with client updates, tunnel drops, and full-network exposure. DefensX replaces the VPN experience with secure, browser-based Zero Trust access that reduces tickets, improves security, and deploys with zero client installs.
VPN clients create unavoidable overhead when supporting diverse networks and endpoints.
Modern SaaS, remote work, and contractor-heavy environments benefit strongly from app-level Zero Trust access instead of full network tunnels.
A useful comparison for MSPs evaluating migration benefits.
| Capability | Sophos Connect | DefensX |
|---|---|---|
| Access model | Full network VPN | Zero Trust app access |
| Client footprint | Installed client + drivers | 100% browser-based |
| Security exposure | Broad network access | Per-app isolation |
| Support load | High — client failures, routing, DNS | Low — no tunnel to troubleshoot |
| BYOD safety | Limited | Secure via browser isolation |
| Zero Trust alignment | Not aligned | Fully aligned |
It’s not just a VPN replacement it's a transformation of how remote access is secured, deployed, and maintained.
MSPs use DefensX to eliminate VPN complexity while improving user experience and reducing their attack surface.
