Why each option
A privacy filter is a physical screen overlay that uses micro-louver technology to darken the display when viewed from side angles, ensuring only the person directly in front of the monitor can read the screen.
Keyboard filters are hardware or software components that restrict or log keystrokes and do not protect data visually displayed on a screen.
Privacy filters use polarized micro-louver film attached to the monitor surface that restricts the viewing angle to approximately 30 degrees from center. This prevents visual eavesdropping (shoulder surfing) in public or open-office environments, directly protecting sensitive financial data displayed on screen from unauthorized viewers without requiring any software configuration.
Screensavers activate only after a period of inactivity and do not protect data that is actively displayed during normal use.
Secure display drivers are not a standard product category and do not provide a mechanism to restrict the physical viewing angle of a monitor.
