Some applications may behave differently when NordVPN or another VPN is connected because the app sees the VPN server’s IP address and network route rather than the user’s normal internet connection. Applications and online services can also apply their own security, location or network policies to VPN traffic.
Why can a VPN interfere with an application?
Possible causes include an application blocking known VPN IP addresses, DNS behaviour, location checks, firewall or security software, or a conflict with the VPN protocol being used. NordVPN’s support guidance for connection and service problems commonly recommends trying another server, changing connection settings, clearing application or browser data where appropriate, or testing the service without the VPN to isolate the cause.
Some applications also need access to local devices or networks. Depending on the VPN configuration, routing all traffic through the VPN can affect those connections.
Why does application access matter more for businesses?
In an enterprise environment, employees may depend on SaaS platforms, private applications, cloud services and internal systems throughout the working day. IT teams therefore need more than an encrypted tunnel. They need control over which users can access which applications, along with visibility and consistent performance.
NordVPN is primarily a consumer VPN. Cloudbrink is designed for secure enterprise access and remote work, using Zero Trust Network Access to connect authorised users to approved business resources. The objective is not to replace NordVPN for personal use, but to address the more complex application-access requirements of organisations.
