Virtual Private Networks (VPN) and Security

Virtual Private Networks (VPN) use the public telecommunications infrastructure but maintain privacy through the use of special tunneling protocols like Microsoft's IPSec and PPTP, but with additional security procedures. A VPN gives a company the same capabilities as a system of owned or leased lines to which that company has exclusive access. However, costs are much lower because the VPN uses the shared public infrastructure rather than exclusive line access. Duos Virtual Private Networks (VPN) provide data and communications security while enabling the internet or extranets to act as an extension of your company's network. Other benefits include:

• Increases corporate network security level
• Enables remote users full access
• Increases remote user access ease of scalability
• Reduces remote network access costs through use of a local internet service provider
• Reduces dialup equipment/remote access server purchase and maintenance cost
