Several new projects are being staffed by outside contractors who will be working on servers in the contractors' office, not in the company building, and will have their own VPN server. The contracting company has informed your company that none of its people will be working weekends. What VPN controls can you set up to minimize contract employees' access to your network?

The VPN control that can be used to minimize employee's access to your network is, by enabling NAP VPN server which monitors client  computer trying to access your network, this is made possible by the NAP enforced client.
