What is a significant disadvantage of a leased line?

A significant disadvantage of a leased line is indeed the high monthly rental costs for dedicated service. Leased lines provide a guaranteed, fixed bandwidth for communication between two locations, which ensures consistent performance and low latency. However, this level of service comes at a premium price.

Businesses and organizations that opt for leased lines typically do so to meet the demands of carrying sensitive data or applications that require continuous and reliable connectivity. The recurring costs can be a substantial financial burden, especially for small to medium-sized enterprises. This makes leased lines less appealing compared to other forms of connectivity that might offer suitable performance at a lower cost, such as broadband or other shared solutions, albeit with possible drawbacks in reliability and speed.

While other options present potential issues—such as low transmission speeds, intermittent connectivity, and compatibility concerns—the primary drawback that stands out for many users is the expense associated with leased line services.
