Leased Line Internet vs. VPN- Which is Preferable?

The Difference between a Leased Line and a VPN-
A leased line delivers a dedicated connection providing lots of bandwidth, but it typically provides no authentication or encryption.

A VPN (virtual private network) provides authentication and encryption over a connection that already exists, which might be a leased line or it may be an ADSL connection or it could also be a mobile network connection.
Your bandwidth requirements determine whether you require a leased line. Your security requirements determine whether you need a VPN.

Leased Line vs VPN - Which Is Cheaper?
VPNs are comparatively cheaper than leased lines. Industries regularly get leased lines for each of their chief offices and connect these together to form a wide-area-network (WAN). Several such businesses, but not all of them, run a VPN over the top of their leased lines to scramble the data flowing between their sites. In real-world terms this means they have a firewall at every office, confirming that internet traffic is scrambled before it leaves the premises of the company.

Several businesses let their staff work from home and to enable this they permit some members of their staff to join the office network remotely. Usually, this is achieved by installing an SSL VPN service or an IPsec VPN software on the employees' company laptops. Either of the VPN technology is selected, employees then join the corporate network through their usual Internet connections that will usually be 'consumer' broadband connections from Internet Service Providers.

Even though VPNs and leased lines are dissimilar, cost does play a role in some 'leased line vs VPN' decisions. For example, let's say you wanted to provide 20 employees with remote access to their work PCs from home. It would be expensive to pay for each employee to have a leased line. 

VPN vs Leased Line - Which Is More Secure?
VPN technology was solely created to provide cyber security and Leased were created with the intent to provide connectivity. Leased lines and VPNs solve very different problems. This doesn’t mean that leased lines are insecure, simply put their job is to deliver connectivity, not authentication or encryption.

Leased line and VPN services are provided by Tikona Infinet, an enterprise arm of Tikona Broadband. Businesses today have Internet supplied to their offices over fiber or cable. With infrastructure work on the escalation and numerous services digging the roads, frequent cable cuts are inevitable. This leads to Internet down-time disturbing businesses, that’s when leased line are optimal. Tikona also provides VPN services to businesses for a safer and secure internet connection.

  1. I've worked on plenty of MPLS networks and leased line internet but never had the chance to build one from the ground up. It's going to be really expensive to set that all up. But many indian vpns are easy to setup and they are cheap too.
