Careful discernment and technological capabilities as sources of strength

Terilogy brings leading-edge technologies and products from overseas to the Japanese market as quickly as possible—this is our fundamental approach to doing business. We work with international consulting companies and venture capital firms to discover unique, cutting-edge technology and product providers before our competitors do, and then proceed to build new markets in Japan together with overseas manufacturers.

Our technical staff, who are responsible for introducing new technologies and products, travel overseas to visit manufacturing companies and equip themselves with practical skills and knowledge on the world's leading technologies. As a result, they are able to approach domestic computer manufacturers in Japan—with a central focus on products lacking major system integrators—in order to not only introduce specific products, but also offer comprehensive solutions through carefully tailored product combinations. Moreover, these staff provide year-round, 24-hour maintenance services for Terilogy products and technologies.

Our representatives are thus able achieve reliable integration and operation of technologies and products that are completely new to the Japanese market, and in this way they have earned the unwavering trust of customers since Terilogy's founding. We even make use of the knowledge and skills gained through working with these leading-edge technologies to develop our own products in-house.

Tackling challenges relating to business operations, corporate management and the nation as a whole

In today's world, cyberterrorism has evolved from targeting daily business operations alone to attacking central corporate management and even entire nations. Here at Terilogy, we provide quick responses via Threat intelligence services and other such services.

Our efforts include network security support measures for national projects and undertakings at the upcoming 2020 Tokyo Olympic and Paralympic Games and World Expo 2025 in Osaka, as well as measures related to communication challenges in response to rapidly growing numbers of international tourists in Japan, innovations in Japanese workplaces, and other issues faced by modern-day Japan.

Amid such endeavors, our firm focus on information networks remains unchanged. Moving forward, we will continue to grow and adapt to changes throughout society as we tackle even larger, more complex, more challenging problems.
