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

Can we protect critical infrastructure and production facilities? The only option to physically "cut off" the intrusion route of ransomware: "OWCD."

Firewalls, VPNs, gateways, virus check and access authentication software—these vulnerability countermeasures are actually almost impossible. Maintenance is difficult, and no matter how much zero trust security is said to be foolproof, the reality is... In a certain survey, it was found that the average time to realize a ransomware attack is 349 days; in fact, the breach has already occurred. Whether or not actual damage occurs depends on the intruder. For critical infrastructure, production facilities, IoT data collection, and system operation monitoring (SYS-LOG) checks, a mechanism that reliably halts communication with the outside is essential. Data diodes physically guarantee one-way data communication, completely blocking external intrusions. We realize a "zero trust" barrier that cannot be fully prevented by firewalls or software controls through hardware. There is a rapid increase in cases utilizing this for real-world responses to cyber terrorism and cyber attacks, pursuing zero trust integrity! We offer evaluation units for loan; please check it for yourself. There are explanatory videos at the related links below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

Physical Layer One-Way Communication Restriction Device "Data Diode OWCD"

One-way shutout! A communication restriction device that physically enhances security.

The "Data Diode OWCD" is a physical one-way communication restriction device that physically limits communication to one direction. No configuration is required for one-way communication. Because there is no physical (electrical) connection, it cannot be mistakenly connected like a firewall due to configuration errors. Additionally, we provide a standard data file transfer program. When a data file is written to the transfer folder of the upstream PC, it is transferred to the output folder of the downstream PC. 【Features】 ■ No configuration required for one-way communication ■ By switching the front panel switch, it is possible to switch between one-way communication and two-way communication modes ■ Monitors the state of the switch and notifies the upstream network ■ Standard data file transfer program provided *For more details, please refer to the PDF materials or feel free to contact us.

Introduction to OWCD OPC UA Support

Let's protect important infrastructure with the enhanced security measures for each line, utilizing OPC UA, which is advancing in production equipment communication!

One-way communication restriction device data diode "OWCD" introduces "OPC UA communication"! OPC UA, which is platform-independent and seamlessly integrates various communication information, offers extremely high flexibility and demonstrates connectivity benefits throughout the entire production process. By utilizing flags categorized by industry, unified information can be obtained even from different production equipment manufacturers, further enhancing production DX efficiency. It is expected to continue spreading towards the standardization of industrial communication technologies. While OPC UA can implement security measures such as encryption on its own, the ability to cross segments that do not require "dialogue" can lead to security holes. This is where "OWCD" comes into play. Even when utilizing settings with firewalls and switches in the information transmission circuit, maintenance can be cumbersome, and mistakes can occur, especially if outdated firmware prevents passage. The "OPC UA compatibility" of OWCD does not require configuration for one-way communication. It is hassle-free and reliable. We respond to the future security needs of various production equipment!! There is an explanatory video at the related link below! For inquiries, please use the "Contact Us" link provided.
