Difference Between Leased line versus VPN security

A leased line is a dedicated connection with a large amount of bandwidth, however, it usually lacks encryption and authentication.

A VPN (a virtual private network) encrypts and authenticates data over an existing connection. It’s possible that’s a leased line. It’s possible that it’s an ADSL connection could be a link to a mobile network.

Whether or not you need a leased line is determined by your bandwidth requirements. Whether or not you require a VPN is determined by your security needs.

Which is less expensive: a leased line or a VPN?

VPNs are less expensive than leased lines, but that’s like saying a padlock is less expensive than a highway. True, but it’s not a terribly instructive analogy.

Businesses frequently obtain leased lines for each of their key offices and connect them to establish a network.

Businesses frequently obtain leased lines for each of their key offices and connect them to create a wide-area network. Many, but far from all, of these businesses, use a VPN to encrypt data moving between their locations over their leased lines. In practice, this means that each office has a firewall that encrypts internal traffic before it leaves the company’s grounds.

Many companies allow employees to work from home, and to make this easier, they allow some employees to connect to the office network remotely. This is typically accomplished by providing an SSL VPN service provider (which allows employees to access IT resources using a conventional web browser) or installing IPsec VPN software on the network.

Employees connect to the corporate network using their ordinary Internet connections, which are often ‘consumer’ broadband connections from Internet Service Providers such as BT, Sky, Virgin Media, and TalkTalk, regardless of VPN technology used.

Difference Between the Leased lines and VPN

Despite the differences between leased lines and VPNs, the cost is a factor in some VPN vs leased line selections. Let’s imagine you wanted to give 20 employees remote access to their work computers from their homes. Paying for a leased line for each employee would be prohibitively expensive. The only viable solution is to allow them to join your network via (much less expensive) internet connections. You’d use a VPN to protect the security of your company’s network.

When determining how to connect a UK office to an international site, the cost is a factor to consider. Leased international lines are prohibitively expensive. So often, businesses are compelled to settle for a less expensive option: purchasing an Internet connection locally in each area, and then using a VPN to encrypt data across their many foreign locations.

Choose Between Leased line and  VPN: 

Choosing between a leased line and a virtual private network (VPN) could be a mistake. Your connectivity needs will determine if you need a leased line, and your security needs will determine whether you need a VPN. Both technologies are used by numerous firms, and they are usually independent of one another.

Which is More Secure: VPN or Leased Line?

Security is provided through technology. Leased lines are used to link people. VPNs and Leased Lines address very different issues. That isn’t to suggest that leased lines are insecure; rather, their primary function is to offer connectivity rather than encryption or authentication.

VPNs encrypt the data you send and receive. This means that anyone eavesdropping on your connection would only see meaningless gibberish rather than sensitive information. VPNs not only encrypt your data in transit, but they also ensure that the parties to whom it is sent are authorised (in general) to receive data from your network and that the parties transmitting data are who they say they are, i.e. authentication at the VPN tunnel end-points ensures that the parties transmitting data are who they say they are.

Leased lines exist to address a Different issue: 

data must travel from one location to another swiftly and reliably. Leased lines can deliver up to 10,000 megabits per second downstream (compared to 12 megabits per second for a typical UK ADSL connection) and 10,000 megabits per second upstream (compared to roughly 1 megabit per second for a typical UK ADSL connection).

 Leased lines are more Reliable than broadband, and significant problems are usually resolved in hours rather than days. Leased lines are typically ‘unmetered,’ which means you can transmit and receive as much data as you want without worrying about quotas or fair usage standards. Some leased lines allow traffic to be prioritised, ensuring that time-sensitive traffic like phone calls and video may be sent quickly.
