| Individual users and small businesses that cannot afford the cost and administrative requirements of a large private voice and data network can use VPNs for remote communications. Using the internet as the network infrastructure, VPNs connect remote users to websites and private corporate networks and their embedded resources with software and appliances that translate internal data streams into secure encrypted transmissions. The technology has been around for decades and is among the most popular remote access technologies.VPN technology can be relatively inexpensive, especially with free or low-cost VPN packages. In these offerings, users simply access the VPN service, complete secure access procedures and enter the desired domain, such as a website address. More costly VPN technologies are likely to be used for large corporate networks. The main cost is the license fee for each user who uses VPN services.VPNs also have several limitations. The principal concerns revolve around data security. If vendors say their security policies are rigorous and compliant with security standards, then those claims should be verified. Vendors could monitor user online transactions and use that information for their own purposes, such as selling customer data to other vendors.The need to mask IP addresses may be exaggerated by vendors that claim a user IP address may be vulnerable to unscrupulous activity. Vendors that log VPN activity may sell user transaction information to other firms. VPN service providers may offer services to prevent DNS issues, such as leakage of user IP data when it should be secure. -- ???????? | |||
