Systems Engineering Consultants Co.,LTD. (SEC) is a specialist real-time technology company with a desire to contribute to the safety and development of the networked society.


Founded in 1970, SEC initially focused on the development of space systems incorporating minicomputers based on our core real-time technology. We also developed applied technologies for public infrastructure system measurement and control. Our focus has now shifted to embedded software for smartphones in the wireless field and other applications, but real-time technology has remained a constant part of our business.

Today we are focusing in particular on ubiquitous technology. This technology makes our lives safer, easier, more comfortable, and efficient by connecting everything around us to computer networks. Real-time technology that is synchronized, responsive, and instant will sit at the heart of this networked society. We are aiming to propel SEC into a new phase of growth, guided by this strategic vision of the networked society.
