Guardian Privacy Filters help keep companies compliant with privacy laws. The main complaint with privacy filters is that they make your screen darker even when viewed straight on by the user. Our filters let more light through than the competition while still greying out the screen when viewed from the side to keep the on-screen data unreadable. This is not a black-out screen, it is a privacy filter that protects your data while remaining user friendly. Yes, your boss will still be able to see that you are playing games! There are two attachment methods. It comes with tape strips if you want to stick it directly onto your screen, and it comes with tabs that stick to your bezel so the filter can slide down behind the tabs and be easily removed and replaced when needed.
