A remote maintenance tool using a completely different method from traditional approaches. No internet connection is required; you can securely connect remotely with just this one device.

"KUROKO Connect" is a remote connection service that packages software utilizing a mobile closed network and patented technology in a cloud environment, fulfilling all three criteria of "safety," "affordability," and "speed." "This product won INNOVATOR AWARD in Singapore in 2025 by Cyber Security Agency of Singapore" In industries such as manufacturing, it allows for safe remote connections to control systems even in closed environments like factories. It is also compatible with operating systems that are no longer supported. KUROKO Connect uses a mobile closed network that is separate from the internet, and its unique connection method, which does not require opening ports, ensures a very high level of security. Moreover, by simply connecting KUROKO Gear (a compact device) to the target control equipment (via LAN, serial, or Wi-Fi), there is no need to install software on the control equipment, enabling immediate remote connection. [Benefits] ■ Remote maintenance is possible even without an internet connection. ■ Usable in factories that are using unsupported operating systems. *For more details, please download the material (PDF) and/or feel free to contact us.
