Thailand's Trusted
Infrastructure Partner
30 years building and operating fiber, cloud, and managed services for enterprise Thailand — with the certifications and NOC to back it up.
Built from the Ground Up in Thailand
KIRZ Co., Ltd. was founded in 1995 with a single mission: deliver enterprise-grade IT infrastructure that Thai and multinational companies can genuinely rely on. Over three decades, we have built the fiber, the cloud, and the NOC to make that promise real.
Today KIRZ operates over 1,000 km of owned dark fiber across Bangkok — both aerial and underground — connecting more than 30 carrier-neutral data centers through 35 SR-MPLS PoP nodes. Our infrastructure is the backbone for hundreds of enterprise customers across financial services, healthcare, government, retail, and manufacturing.
As a locally owned and operated provider, KIRZ is uniquely positioned to serve organizations that require data sovereignty, Thai-language support, and a partner who understands both the technical and regulatory landscape in Thailand.

Built on Industry-Leading Platforms
KIRZ is an authorized partner and reseller for the platforms that power our services — giving customers direct access to vendor support and licensing through a single local provider.
What Sets KIRZ Apart
We are not a reseller of someone else's network. KIRZ owns and operates its own fiber, its own cloud, and its own NOC — giving us end-to-end accountability that third-party aggregators cannot match.
Owned Infrastructure
1,000+ km of dark fiber, 35 SR-MPLS nodes, and private cloud — all KIRZ-owned and operated. No dependency on third-party carriers for core services.
24/7 Thailand NOC
Our NOC is staffed in Bangkok around the clock. SLA commitments are backed by engineers who know the network intimately — not an overseas call center.
Data Sovereignty
All services are delivered from Thai infrastructure. For organizations subject to PDPA, BOT, or government data residency requirements, KIRZ is the compliant choice.
Single Point of Contact
One SDM and one NOC team for all services — fiber, cloud, colo, security, and VMS. No vendor-to-vendor finger-pointing when issues arise.
