There are a couple of possible reasons for the discrepancy. Perhaps, remote workers think that no one is watching what they are doing because they are out of the office. Maybe, their inhibitions about someone walking by and viewing what is on their screen disappear because they are not sitting in a public place. Perhaps, they are using company computers to view these materials on what they regard as their own personal time on the road.
Regardless of the underlying rationale, remote users viewing habits create a couple of problems for small and medium businesses. The fact that so many of these workers are visiting illegal file sharing sites leaves their employer open to possible legal prosecution for the offense. The discrepancy also means that remote workers are not as productive as they could be.
ScanSafe obviously wants companies to use its services to bring the remote usage patterns in line with their office co-workers, and such services can be helpful in achieving that goal. In addition, small and medium businesses need to educate their employees about the proper use of company computers, especially when they are on the road. Maybe then, employees will prove worthy of your trust.
How many of your employees work remotely? What security checks do you have in place for them? Would you be surprised if their viewing patterns differed from individuals working in the office?
