An International Private Leased Circuit is a dedicated, point-to-point connection between two locations in different countries — for example, your Mumbai office and a London data centre. The bandwidth is reserved just for you, symmetric in both directions, and the traffic runs on a private path rather than the shared public internet, with an end-to-end SLA on availability and latency.

It depends on how critical the link is. IPLC gives guaranteed, private, low-latency performance for mission-critical routes (banking, trading, data-centre interconnect). SD-WAN is flexible and cost-effective for most multi-site WANs, intelligently using internet and other links. An IPSec VPN secures a site-to-site link cheaply over the public internet, and a remote VPN connects individual users. Many enterprises mix them — IPLC for the few routes that must never falter, SD-WAN or VPN for everything else. The table above breaks it down dimension by dimension.

An unprotected (standard) IPLC runs over a single path. A protected IPLC adds a second, diversely-routed path so that if one route fails — say an undersea cable is cut — traffic automatically continues on the backup. Protection costs more but is essential for links that genuinely cannot go down.

IPLC is typically priced per Mbps per month, and the rate depends heavily on the route (which countries and undersea systems), the bandwidth, whether you want protection, the contract term and the last-mile access at each end. Higher bandwidths and longer terms usually lower the per-Mbps rate. The comparison shows indicative per-Mbps pricing so you can gauge the range before a formal quote.

Because it's a physical, end-to-end circuit across carriers and often last-mile builds at both ends, an IPLC usually takes a few weeks to deliver — longer than an internet-based VPN or SD-WAN link. We flag expected timelines per route so you can plan, and can suggest an interim option if you need connectivity sooner. This is general guidance, not a substitute for a formal feasibility check.
