So we were considering using this as an option for our business and I had an employee install. I was able to identify and lock the device. He simply restarted the computer and had full access again and went right back to work. PREY only let him shut it down, but he then just turned on the power button. He has access to the internet as we're still able to use skype for business, but PREY indicates that the device cannot be contacted. Is this a known issue? This seems to completely defeat the purpose of this program if a simple reboot bypasses it. Can anyone provide some insight?
