NAP and VPN Connections
NAP is a technology in Windows Operating Systems that restricts network access based on an assessment of a client computer’s health. A compliant client that meets the health benchmark is able to access the network. If the computer does not meet the health benchmark, it is noncompliant. NAP blocks noncompliant clients from accessing the network.
Administrators can configure NAP to restrict network access based on
the following criteria:
Does a client have antivirus software installed and up to date?
Does a client have anti-spyware software installed and up to date?
Does a client have Windows Firewall enabled?
Are automatic update enabled?
Have all software updates been installed on the client computer?

Whereas dial-up connections use the PSTN to carry traffic to your internal network, VPNs traverse the public Internet. The figure below illustrates how connections are established, with each client requiring a separate Internet connection but the VPN server requiring only a single connection to the Internet (instead of a separate physical circuit per dial-up client).

Advantages of VPN
Enhanced security – The data is kept encrypted and secured when you connect to the network through a VPN. In this way, it keeps the information away from hacker’s eye.
Remote control – One of the biggest advantages of having a VPN is that the information can be assessed remotely even from home or any other place in case of company. In this way, VPN increases the productivity within a company.
Share files – If you have a group that needs to share files for a long time period, then a VPN service can be used.
Online anonymity – The web can be browsed in complete anonymity through a VPN. Compared to web proxies or IP software, VPN service allows you to access both websites and web applications in complete obscurity.
Bypass filters and unblock website – VPNs proves to be great for bypassing Internet filters and accessing blocked websites.
Change IP address – VPN is helpful when you require an IP address from another country.
Better performance – Efficiency of the network and Bandwidth can be increased once there is an implementation of VPN solution.
Reduce Costs – The maintenance cost is very low once VPN network is created. Once a service provider has opted for you then the surveillance and network setup is no more a concern.
