What ONION TECH LIMITED does
ONION TECH LIMITED (Onion Technology) is a South Korea-headquartered, private data center infrastructure software and hardware vendor founded in 2000, operating through ONION Software, Inc. in Korea and ONION Technology Pte Ltd in Singapore. The company develops MK119 Data Center OpsWare, a web-based unified monitoring and operations platform that consolidates BMS, EPMS, and DCIM subsystems into a single real-time analysis environment with an open, vendor-independent architecture; MK119 is reported as Korea's first dedicated data center management solution (launched 2008) and is used at over 200 data centers by 150+ customers, including Singtel, ST Engineering, Digital Edge, and Neutra. ONION complements the platform with a proprietary hardware portfolio — the THP10 and T10 environmental sensors and the iPSM54 (PDU) and iBSM (Tap-Off Unit) intelligent power meters — that integrates with MK119 via Modbus and open APIs, plus a turnkey engineering, cabling, and commissioning service line executed by an engineering workforce that the company states is 90% engineers.
ONION generates revenue through three streams: subscription- or license-based sales of MK119 software, hardware sales of its sensors and meters, and professional services for turnkey installation and maintenance. The go-to-market is direct enterprise sales, augmented by active participation in W.Media Cloud & Data Center conferences across Korea, Japan, Singapore, Philippines, Indonesia, Hong Kong, and Vietnam, and self-organized events such as the 2025 Data Center Innovation Conference co-hosted with Rockwell Automation, Cisco, and MakinaRocks. The company reports over 80% share of large-scale data centers in South Korea, 21+ patents in monitoring/control/optimization, and a portfolio of certifications including IEC 62443-4-1, ISO 27001, bizSAFE Level 3, and ISO/IEC 9126/25041/2505 software-quality standards.
Strategically, ONION is positioning MK119 as the orchestration layer for AI-driven, IT/OT-integrated data center operations. The 2024-2025 MOUs with MakinaRocks (industrial AI), Rockwell Automation (OT/PLC), and Cisco (network/security) extend the platform from passive monitoring into predictive maintenance and AI-based optimization, while a Japan channel partnership with Network Corporation and wholly-owned entities in Singapore and Malaysia underpin the Asia Pacific expansion beyond the dominant Korean installed base. CEO Chang Cho (조창희) leads the founder-led, privately-held company, with no disclosed institutional funding or M&A activity.

ONION TECH LIMITED competitors and assessment
Company assessmentRegional players
- Huawei: Huawei's data center infrastructure portfolio includes Data Center Management (iManager NetEco) and FusionCol cooling solutions sold across APAC and emerging markets. It is a key regional competitor in the same geographies ONION is expanding into.
Broad incumbents
- ABB: ABB provides industrial automation and electrical measurement solutions for data centers, including power monitoring and OT/ICS capabilities. Its industrial automation depth parallels ONION's Rockwell partnership and IEC 62443-aligned positioning.
- Schneider Electric: Schneider Electric's EcoStruxure for Data Centers platform covers DCIM, EPMS, power, and cooling across enterprise and hyperscale operators. It is a broader incumbent whose portfolio overlaps ONION's MK119 monitoring, iPSM54/iBSM metering, and turnkey services capabilities.
- Eaton: Eaton offers data center power management, intelligent PDUs (ePDU), and DCIM software (Brightlayer). Its iPSM54-style branch circuit monitoring directly competes with ONION's PDU/busway metering products.
Others
- Commvault: Commvault delivers data protection and information management for data center and hybrid cloud environments. It is an adjacent ecosystem peer where ONION's monitoring platform may integrate or compete for IT operations budget in enterprise customers.
Direct peers
- FNT Software: FNT provides data center infrastructure management software for cabling, power, and asset documentation in enterprise environments. It overlaps with MK119's unified monitoring and tenant support functions in European and APAC enterprise accounts.
- Vertiv Holdings: Vertiv is a global leader in critical digital infrastructure, offering DCIM software, thermal management, and power solutions for data centers. It is the closest direct competitor to ONION's MK119 platform and power/environmental monitoring hardware, with much larger global scale.
- Rittal: Rittal supplies data center infrastructure including enclosures, power distribution, and monitoring/RiMatrix systems. Its integrated hardware-software approach parallels ONION's MK119 + THP10/T10/iPSM54/iBSM bundle.
- Sunbird Software: Sunbird Software's DCIM suite (including Power IQ and Data Center Planner) competes directly with MK119 on power, environmental, and asset monitoring for enterprise data centers. It is a relevant comparable in the same niche.
