There may be certain cases where you may wish to obscure the work being done on computers from anybody other than the immediate user. If you have receptionists working in a busy front lobby, it may be a good idea to prevent visitors from performing shoulder surfing attacks, stealing passwords or sensitive company details from the receptionists’ screens. If your work requires frequent travel and remote use, it would be smart to prevent strangers from looking at your laptop screen when you work from airports or restaurants. Privacy Filters are a physical security control that accomplishes this.
Privacy Filters are thin tinted sheets that are placed over computer monitors, preventing passersby from being able to see the contents of your screen. Only you as the user can see the contents of your screen. Privacy Filters can also provide additional benefits such as blocking blue light.
It is worth considering Privacy Filters if you have computers placed in areas with large amounts of public traffic, or if you frequently perform remote work from public places. Filters can be purchased from various vendors with differing levels of quality. Before purchasing any for your business, ensure that you select the filter size that is appropriate for your monitors. It is always a good idea to buy a few extra so that you have additional filters on hand for replacements or in case new devices are ever introduced in the environment.
