Virtual Private Networks (VPNs) allow organizations to securely extend their LANs over the Internet by encrypting the data traffic. VPNs create the ideal infrastructure for providing a secure method for the exchange of data and network resources with employees, partners, suppliers and business associates.

Internet-based remote access presents challenges in protecting the confidentiality and integrity of essential business information as it travels over the public Internet. Hackers using packet sniffers can capture the data as it passes over the Internet and convert it into a readable format or gain entry into your network. Exposure to these security risks means unauthorized users can initiate fraudulent transactions, as well as steal, alter, or destroy confidential information, exposing your organization, customers, vendors, and business partners to financial losses.

To ensure data security on the Internet, there are three requirements:
  • Remote user identity authentication
  • Secure private transmission of data (no unauthorized listeners)
  • Verification of unadulterated data transmission

How VPN Works

A VPN is an umbrella term that refers to all the technologies enabling secure communications over the public Internet. VPN uses "tunnels" between two gateways to protect private data as it travels over the Internet. Tunneling is the process of encapsulating private IP packets into a public IPSec packet. Once the authentication and authorization between the VPN gateways is established, the tunnel is created and the users can send and receive data across the Internet.



Why VPN?

Virtual Private Networks (VPNs) not only allow small, medium and large enterprises to implement remote access via the Internet but it also delivers compelling benefits for organizations to work smarter, reduce costs, and gain competitive advantage.

VPN: A Cost Effective Remote Access Solution

VPNs are creating a revolution in remote access by replacing expensive leased lines and usage-based dial-up connections with ubiquitous Internet connections. With VPN technology, companies of any size can use the Internet to broaden the reach of their Intranets and Extranets. By replacing expensive leased lines or long-distance telephone usage charges with local connections to Internet service providers (ISPs), companies save money because local Internet connections are less expensive. Mobile employees can simply dial into a local service provider, eliminating the need for costly 800 numbers and modem banks.

VPN is a Strategic Necessity

Today, remote access to information and corporate resources is a strategic necessity for any size business. A remote access solution:

  • Arms employees with up-to-date information, enabling them to make the most informed decisions possible.
  • Streamlines access to information and enables centralization of mission-critical data and content.
  • Reduces networking costs by using the Internet to replace in-house WAN and dial-up networks.
  • Extends the workplace beyond the office walls to allow people to be fully productive at home and on the road.
  • Provides an edge in recruiting employees looking for flexible work schedules.
  • Fosters competitive advantage by creating closer links with customers, suppliers and employees.
  • Increases employee productivity through workplace flexibility
  • Allows network administrators to centrally enforce security policies.
