What Is a Leased Line?
A leased line is a dedicated, private internet connection used exclusively by a single business – you don’t share this connection with any other business so you enjoy all of the benefits like:
✔ Symmetrical speeds – Equal upload & download speeds.
✔ Guaranteed performance – 99.99% uptime backed by an SLA.
✔ Ultra-low latency
✔ Scalability – Speeds can be increased as your business needs grow.
Soi f you need fast, reliable internet for cloud-based services, remote work, and large data transfers, leased lines could be a good option.
Leased Line Speed Options & Their Best Use Cases
Leased line speeds range from 10Mbps to 10Gbps, and the right choice depends on business size, usage, and scalability needs.

- 500Mbps+ is best for 100+ users with high data consumption.
As a general rule, allocate 10Mbps per user for optimal performance.
