Best IPSec VPN Providers

Virtual Private Networks, commonly referred to as VPNs, enable business organizations to enjoy private and secure communications whenever they access the internet by way of public network infrastructures. A VPN is basically a network of associated hosts that communicate over a public network connection, like the internet, while using authentication and encryption technologies to maintain the privacy of the data it carries by concealing it from public eyes and protecting it from being accessed or thieved by unauthorized users. A typical VPN service is used to securely connect mobile users, home workers, partners, and remote branch offices over the public network connection.

VPNs are usually created with the help of various different technologies, which are inclusive of Multi-protocol Label Switching (MPLS), Secure Sockets Layer (SSL), and most importantly Internet Protocol Security (IPSec). You will most likely be in need of a virtual private network if you happen to own a business organization or work in one that has one or more of the following requirements:

  • To secure crucial business communications from being viewed by prying eyes,
  • To link hosts or networks at different branch offices or distant locations securely,
  • To bring together the ranges of different IP addresses into a single address space that is even more convenient to access,
  • To ensure the integrity of all business data that are exchanged over the public network connection, and
  • To provide a secure access to the network of the workplace to all telecommuters.

What is IPSec?

Internet Protocol Security, IPSec, is the most commonly used technology for establishing VPN connections. The protocol basically describes the ways in which confidentiality, authenticity, and data integrity can be provided over a public network like the internet. It succeeds doing this by way of authentication, encryption, and tunneling, but also allows business organizations to choose the definitive security policy that would be suitable for their business operations. Following are the three configuration choices available for best IPSec VPN providers:

  • Authentication: Usually asks for a username and password, digital certificates like VeriSign or Entrust, or username and token plus pin.

  • Tunneling: Encapsulating Security Payload (ESP) or Authentication Header (AH).

Components of IPSec

Having seen the three different configurations of best IPSec VPN providers, we now move on to discuss the three major components of the same:
