DETECTION OVERVIEW

VPN Gateway Access from an Unusual Location

Risk Factors

There are legitimate reasons why a user could be connecting to your VPN from outside your country. But if the VPN connection is from an unknown origin, the likelihood is high that an attacker is attempting to compromise your network. An attacker with any skill level can connect to a VPN across international borders. A connection to a VPN gateway can enable other attacks, such as port scanning, lateral movement, or data exfiltration.

The system might change the risk score for this detection.
