Supporting a world where everything
is connected to the Internet.

With IoT, everything is connected to the Internet. This means the data volume generated on the Earth will increase tens of times the current size, which means our daily lives will undergo major changes. The more convenient the world becomes, the more sensations, excitement, and joy will flood the Earth. With super parallel, ultra-disperse, and ultrafast speed as our core competence, JIG-SAW supports and protects IoT and the digital universe ahead.


We provide security for the Internet (IoT)
and promote automation, decentralization,
and sharing in all industries.

JIG-SAW is a company whose mission is to provide security for the future of the Internet (IoT). Because the Internet has become a substantial part of society's infrastructure while its use has spread throughout the overall population and into many objects, we would like to contribute to a prosperous future by providing security for all activities on the Internet. System management supports the Internet in the era of data control. JIG-SAW promotes automation, decentralization, and sharing by all industries with our concept of A&A. In IoT, billions of people and trillions of objects on the Earth are connected to the Internet, followed by the world of DU: Digital Universe. Eyeing all of these, we continue to lead the next-generation of data control by researching, developing, and releasing various algorithms, cooperating in-depth with people in various positions throughout the world for systems and services, and always being aware of the next generation of technologies in the field of Internet (IoT) data control.


In the era of data control by A.I.

With IoT, everything is connected to the Internet. Conventional system management has changed into data control through AI and expanding into an incommensurable market. As everyone knows, the Internet has grown explosively on the Earth. We have entered the era of IoT where billions of people and trillions of objects are connected, which has penetrated deep into all industrial fields.

We are in the era of data control where trillions of things connected to the Internet are automatically supported by AI.

Our vision is focusing on all “things” connected to the Internet system across all industries and realizing IoT data control based on our concept of A&A.

IoT data control is the most important core for the Internet (IoT), which requires constant technological renovation and unprecedented innovation. Focusing on new services and the latest moves in the world, we have been contributing to automation, decentralization, and sharing of the IoT system connected to all industries based on basic and generic technology. Incorporating all of these into services for customers and evolving them into a vertically integrated model based on a variety of distributed technologies, we provide services in the firm belief that a future-oriented company should process all operations automatically, continue to transform itself, and grow exponentially. We are in the era of the Internet (IoT) for all industries, which is quite different from the history of the Internet and is followed by IoT data control. JIG-SAW is a future-oriented company that supports it. We hope you look forward to our efforts in the future.
