Virtual Private Networks (VPN)
Virtual Private Networks (VPN) are networks, spread over the general network infrastructure. VPN offers the same level of security, management and access levels, as private local networks. The advantages of VPN are lower cost and increased ability to connect remote computers, mobile users and offices, as well as adding new segments, users and providers.
VPN offers the following solutions for different users:
- For large businesses VPN is a global alternative infrastructure that substitutes or expands already existing private networks that use leased lines or ATM lines. In addition the VPN provider can offer additional complex services, specially developed for the client.
- For service providers, VPN represent an essential building block in contemporary services, as VPN can be used by clients as well.
- For small and medium business, VPN connects separate offices, and remote users, through the use of a common or public network, for example the Internet, but with the security and functionality of a private network.
VPN for the business
Virtual Private Networks (VPN) connect separate offices, and remote users, through the use of a common or public network, for example the Internet, but with the security and functionality of a private network. By comparison to a private network, the use of a common global network infrastructure lowers the cost and speeds up integration.
The building of VPN can use wireless technologies. Once build VPN, can allow the use of corporate IP telephony.
Advantages:
- Lower cost - When using VPN, companies can save the cost of expensive leased lines. Remote users can be connected to the corporate network, through a local Internet provider, instead of costly long distance telephone calls.
- Security - VPN uses the highest level of security, through expanded encryption of authorization protocols, which protects the user data from an unauthorized access.
- Scale - VPN allows corporations to have access to a remote infrastructure, via Internet providers. This allows corporations to have the capacity for practically unlimited network expansion, without the need for a significant infrastructure.
- Compatibility with broadband technology - VPN allows mobile employees to use the advantages of high-speed broadband connection DSL, when they connect to their corporate network.
