I like how easy it was to install with minimal knowledge required! It's very intuitive as well so anyone who knows computers can use them effectively without any problems or issues whatsoever.
Nothing really bad about anything but if you are looking into something similar then definitely give threat locker some thought before deciding whether its right fit for your needs. They're doing great work protecting my network from potential threats such as viruses/malware etc by scanning all incoming files when they arrive which prevents me having to manually scan each file myself every time i open an attachment (which would be extremely tedious).
