# Detect system VPNs with freeRASP

System VPNs may be used to mask illicit activities, evade compliance controls, or access services from unauthorized regions.

Detecting a running VPN service on mobile devices is critical for security-sensitive applications, as it can indicate potential privacy and security risks.\
VPNs can obscure the user’s actual IP address and route data through servers potentially under external control, which might interfere with geographical restrictions and bypass network security settings intended to protect data integrity and confidentiality.

Such anonymizing features could be exploited to mask illicit activities, evade compliance controls, or access services from unauthorized regions. FreeRASP checks whether the system VPN is enabled.
