Geo-location services can verify an individual's access location and ensure it aligns with predefined secure areas. This can be a key part of a multifactor authentication process where the employee needs to be in a specific location to access corporate resources. In contrast, a virtual private network (VPN) masks an individual's location and is not used to verify a specific location, biometrics verify identity and not location, antimalware software is used to protect against malicious software, and public Wi-Fi is inherently insecure and does not verify location validity.
