At Dan Murdoch Risk Services we designed our own secure Virtual Private Network (VPN) with various IP address locations in the three global regions. This is 'in house' VPN software designed to ensure that our clients intelligence gathering and all investigations are conducted securely and in an anonymous fashion which ensures the privacy of all negotiations when data is collected and investigations and carried out.
What is a VPN?
A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables a computer or network-enabled device to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security and management policies of the private network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. Major implementations of VPNs include OpenVPN and IPsec.
A VPN connection across the Internet is similar to a wide area network (WAN) link between websites. From a user perspective the extended network resources are accessed in the same way as resources available within the private network. One major limitation of traditional VPNs is that they are point-to-point and do not tend to support or connect broadcast domains. Therefore communication, software and networking, which are based on layer 2 and broadcast packets, such as NetBIOS used in Windows networking, may not be fully supported or work exactly as they would on a real LAN. Variants on VPN, such as Virtual Private LAN Service (VPLS), and layer 2 tunneling protocols are designed to overcome this limitation.
VPNs allow employees to securely access their company's intranet while traveling outside the office. Similarly, VPNs securely connect geographically separated offices of an organization, creating one cohesive network. VPN technology is also used by individual Internet users to secure their wireless transactions, to circumvent geo restrictions and censorship, and to connect to proxy servers for the purpose of protecting personal identity and location.

VPN stands for Virtual Private Network. Here's how it works. You, sitting at home, connect to the Internet as normal and then start the VPN software. This sets sets up a secured and encrypted connection to another computer/server somewhere in the world. When you go to a website while connected to the VPN the requests are passed on to that other server and then the information is sent to your computer. Because of the encryption process this cannot be filtered or blocked. To anyone looking at your traffic, it's as if you are actually at the remote server location. So if you live in Sweden and you connect to a VPN with a node in the United States, it's as if you are surfing the web from the US, not Sweden.
Once properly connected to the VPN you will have unrestricted access provided that the node you connect to is not restricted. Anyone looking at your traffic won't be able to see what you are doing.
