Let's protect the core of the data diode one-way communication restriction device "OWCD"!

Is Zero Trust okay? It took 349 days to realize we were breached! Can we protect critical infrastructure and production facilities? Simple and clear security "OWCD."

Firewalls, VPNs, gateways, virus check and access authentication software—these countermeasures are actually nearly impossible to implement effectively. Maintenance is challenging, and no matter how much zero trust security is touted as foolproof, the reality is that... According to a survey, it takes an average of 349 days to realize that a ransomware attack has occurred. In fact, breaches have already taken place. Whether or not actual damage occurs depends on the intruders. As such, there is a significant gap between ideals and reality. It is too late to realize the need for protection after a breach has occurred. For core infrastructure, production equipment, IoT data collection, and system operation monitoring (SYS-LOG) checks, it is essential to ensure that something cannot enter or exit at each boundary. This is where the one-way communication restriction device "OWCD," which allows communication in only one direction while effectively blocking communication from the opposite direction, proves useful. There is a rapid increase in cases utilizing it for real-world responses to cyber terrorism and cyber attacks, as well as the pursuit of zero trust integrity! OWCD has a market share of 14%, but its sales ratio is only 1%. This is proof of its overwhelmingly low price compared to competitors! We will lend you an evaluation unit, so please confirm it for yourself. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

Movement Restriction Device "BB Stopper"

A mobility restriction device that is less likely to cause concerns about individual defeats, making it easier to aggregate the number of installations.

The "BB Stopper" can be used as a movement restriction device with high reaction force and large elongation capacity. In PC girders, large anchor bars and caps can interfere with the upper structure's reinforcement, but this product has minimal interference. Additionally, it is easy to consolidate the number of installations, reducing concerns about individual impacts. 【Features】 ■ Can be used as a movement restriction device with high reaction force and large elongation capacity ■ No cross-section loss occurs when the upper structure is a PC girder ■ Minimal interference ■ Easy to consolidate the number of installations ■ Reduced concerns about individual impacts *For more details, please refer to the PDF materials or feel free to contact us.

Speed Limiting Device "SpeeDAM"

It is possible to prevent violations of the speed limit! The restricted speed can be set arbitrarily.

"SpeeDAM" is a device that allows you to set a specific speed limit for vehicles such as cars, and once the set speed is reached, it prevents acceleration even if the accelerator is pressed. It is possible to prevent violations of specific speed limits in areas such as premises or individual management-required speed limits on highways. Additionally, it can be easily installed as an aftermarket product, regardless of manufacturer, vehicle type, or model year. It is also compatible with motorcycles, construction machinery, forklifts, and more. 【Features】 ■ The speed limit can be set arbitrarily ■ Easy to install as an aftermarket product ■ No restrictions on manufacturer, vehicle type, or model year ■ Compatible with motorcycles, construction machinery, forklifts, etc. ■ Can be turned ON/OFF with a switch *For more details, please refer to the PDF document or feel free to contact us.

Introduction to OWCD OPC UA Support

We have implemented OPC UA, which is being utilized in production equipment communication. It is beneficial for strengthening security measures by line. Let's protect critical infrastructure!

The one-way communication restriction device data diode "OWCD" has previously been utilized either for file transfer or UDP communication. We have now added a new "OPC UA communication" feature! OPC UA, which is platform-independent and seamlessly integrates communication information across various standards, offers exceptional flexibility and enhances connectivity benefits throughout the entire production process. As automation progresses, the production environment becomes even smoother. We will continue to promote the standardization of industrial communication technologies. It enables mutual "dialogue" between different technologies without the risk of erroneous communication, but crossing segments that do not need to "dialogue" can create security holes. This is where the "OWCD" comes into play. Even when using firewalls and switches to configure the information transmission circuit, maintenance can be cumbersome, and mistakes can occur, while outdated firmware may fail to prevent passage. The "OPC UA compatibility" of the OWCD allows for one-way communication without any configuration, making it hassle-free and reliable. We will respond to the future security needs of critical infrastructure and various production facilities!! There is an explanatory video at the related link below!
