The ThinkPad X390 display has PrivacyGuard(Optional), exclusive technology to block its content from any viewing angles other than head-on, and alerts you if a shoulder surfer is trying to see it. ThinkShutter—a physical cover for the webcam—helps prevent outsiders from using the camera to spy on you. Add an optional Hybrid IR (infrared) camera and optional touch fingerprint reader for biometric login, adding another measure of security.
