Privacy is the best policy.
These days, screens are everywhere. And so are visual hackers. With the increase of mobile workers, open workspaces, and the migration of data to the cloud, screens can display private information virtually anywhere.
An unprotected screen can expose sensitive and private information, trade secrets and business plans. And the reality is that a visual hacker may only need one piece of valuable information to unlock a large-scale data breach.
Consider your workplace
Walk through your office to see how easily visual hacking can occur. Any screen you can see can also be seen by a visual hacker.
How privacy filters work
3M Privacy Filters block side views outside the 60 degree viewing angle, while providing a crisp, clear view to those directly in front of the screen.
Microlouver technology
A single microlouver is about as thin as a single strand of hair. There are thousands of microlouvers within one 3M Privacy Filter—all virtually undetectable by the human eye.
Attachment options
3M™ Privacy Filters are custom-cut for Macbooks. They attach with optically clear adhesive strips or easily removable slide mount tabs.
Step 1: Determine your screen type
Does your device have a raised bezel or a flat front glass screen?
Raised Bezel: screen with a raised frame
Flat Front Glass: edge-to-edge glass screen without a raised frame
Step 2: Measure your screen
For a raised bezel screen, measure the height (h) and width (w) of the screen's viewable area within the bezel.
For a flat front glass screen, measure the height (h) and width (w) of the entire glass display.
Step 3: Find your filter
Use the measurements to select the right sized filter for your device from the products listed below.
Best fit tip: if you don't see a filter that matches your measurements, select a filter that is smaller, yet closest to your measurements.
