A freeware application, EMOS is regarded as a utility that helps users to protect the information stored in their systems by masking the user’s IP address. This tool has a small and simple interface that updates the user regarding various activities such as securing the ports, closing the connections, enabling the protection measures, etc. The program is quite intuitive; and therefore, the developers have not offered any Help feature with this tool. It also does not offer any remote PC verification, which allows users to verify the strength of the tool’s claims. These are considered some of the major limitations of this utility.
