Why MSPs are switching from FortiClient VPN to DefensX.

FortiClient’s VPN architecture gives users full network access, requires OS-level client updates, and generates endless tickets. DefensX offers browser-based Zero Trust remote access with less risk, fewer tickets, and better margins for MSPs.

For MSPs looking to modernize remote access and reduce FortiClient VPN dependencies.

Why FortiClient VPN frustrates MSPs

FortiClient VPN still operates like a traditional full-tunnel VPN. It’s reliable for certain legacy architectures, but challenging for MSPs who must secure hybrid work and simplify support across dozens of environments.

Operational drain on MSP teams

Legacy VPN

● OS-specific VPN client installs and version mismatches.
● Frequent “FortiClient won’t connect” or “tunnel drops.”
● Troubleshooting DNS, split tunneling, and routing per customer.
● Difficult to support contractors and unmanaged devices.

Flat network access increases risk

Broad network exposure

● Once connected, users see internal subnets not Zero Trust.
● Compromised credentials can lead to lateral movement.
● No native browser isolation or session protection.
● Hard to enforce granular app-level policies.

How DefensX modernizes remote access for MSPs

DefensX replaces full-tunnel VPNs like FortiClient with isolated browser-based Zero Trust access. Users get only what they need; MSPs get fewer headaches.

App-level Zero Trust access

DefensX ZTNA

● Users access apps, not networks.
● No full-tunnel exposure like FortiClient VPN.
● Strong session protection: isolation, DLP, keylogger defense.
● Perfect for contractors & BYOD without extra risk.

Low-support, high-margin for MSPs

MSP-ready

● No VPN client updates or OS conflicts.
● Standardized access across your entire customer base.
● Built-in reporting for QBRs & compliance.
● Easy to bundle: Remote Access as a Service.

Capability	FortiClient VPN	DefensX
Access model	Full network VPN tunnel	App-based Zero Trust access
Client footprint	Installed VPN agent required	Browser-based secure workspace
Security risk	High — lateral movement possible	Low — isolation & per-app segmentation
Support load on MSP	High — updates, routing, DNS troubles	Low — no tunnel, no drivers, no OS issues
BYOD support	Risky without restrictions	Safe by design (browser isolation)
Future alignment	Traditional VPN architecture	Zero Trust + SASE compatible

FAQ: Moving off FortiClient VPN

These are the objections MSPs hear most often with easy responses to support your case.

“Can DefensX replace every FortiClient use case?”

Yes — for users who primarily need application access (web apps, internal portals, RDP, SSH). Where full network tunnels are required, both systems can run in parallel during transition.

“Is performance better than full-tunnel VPN?”

Typically yes. Since only app traffic flows through DefensX instead of all device traffic, users often see faster performance compared to FortiClient full-tunnel VPN.

“Does this require device management?”

No. DefensX works on both managed and unmanaged devices via secure browser access — ideal for contractors, temporary workers, and BYOD scenarios.
