OpenVPN has long been a go-to VPN tool, but it was built for simple tunneling not modern
Zero Trust, BYOD, or MSP multi-tenancy. DefensX replaces full network tunnels with secure,
browser-based Zero Trust access, reducing risk and dramatically lowering ticket volume.
Perfect for MSPs standardizing remote access across diverse customer networks.
Why OpenVPN is difficult for MSPs to scale
OpenVPN excels as a lightweight VPN, but managing configs, certificates, routing, and client
compatibility across dozens of customers is a significant operational burden for MSPs.
High support overhead
Legacy VPN
● Managing client installs for each OS and device.
● Frequent tickets about configs, certificates, and tunnel failures.
● Routing and DNS issues vary across customer environments.
● Hard to support contractors without exposing internal networks.
Network-level access increases risk
Broad network exposure
● Full-tunnel access exposes internal subnets to anyone with credentials.
● No application-level segmentation.
● No native browser-level protections like DLP or isolation.
● Lateral movement risk if a device or credential is compromised.
How DefensX modernizes OpenVPN environments
DefensX offers app-level Zero Trust access directly through the browser no tunnels, no
certificates, and no client installs. Perfect for MSPs needing consistency across tenants.

FAQ: Moving off OpenVPN
Common questions from customers adopting modern Zero Trust access.
“Can DefensX replace all OpenVPN use cases?”
For users who only require app-level access (RDP, SSH, web apps, internal portals), yes.
For rare full-network needs, run both in parallel during migration.
“What about our existing firewall or server setup?”
DefensX works alongside your existing firewalls, servers, and networks — you don’t need
to replace your infrastructure, only how users access it.
“Do we have to manage certificates anymore?”
No. DefensX eliminates certificate and config management entirely since access happens
inside a secure, policy-controlled browser session.
