02Company
We do not sell promises. We operate networks.
Technology infrastructure behind businesses that never go offline.
Gaisar Teknologi Bersama is an IT company and a national internet service provider. We build and operate infrastructure — fiber optic, wireless and interconnection networks — and we keep it working every day.
Our work runs on two layers at once. On the physical layer, we build and maintain access networks and intercity interconnection. On the service layer, we manage IT systems, monitor performance and deliver digital solutions that hold up an organisation’s daily operations.
That combination lets us serve everyone from households to corporates and government agencies within one framework: measurable infrastructure, continuous monitoring, and a team you can actually reach when it matters.

04Core capabilities
Five service lines that make up one infrastructure.
Each service stands on its own, but they are built to work together — from the internet connection itself, to system management, data hosting, device solutions and interconnection between regions.

05Network
From a single access point to cross-border networks.
The Gaisar network is layered. Each layer adds reach and resilience, so service holds up as an organisation’s requirements grow.
- L1Access & customersBroadband and dedicated connections from the Gaisar network to a customer location — a home, an office or an operational building.
- L2InnercityInterconnection between points inside one city, linking several operational sites within the same area.
- L3IntercityInterconnection between cities, letting data move across service regions without depending on the public network.
- L4InternationalInternational interconnection for organisations that need to reach services, partners or offices outside Indonesia.
