Let's protect the data diode unidirectional communication restriction device "OWCD"!

Are you able to implement multi-layered defense? Can you fully protect critical infrastructure and production facilities? The only option to "physically cut off" communication in one direction is "OWCD."

Cyber attacks have now progressed from targeting "data leaks" to aiming for "operational shutdowns" of companies. OWCD physically disconnects communication in one direction, fundamentally cutting off unauthorized intrusions and leaks. It builds a "Zero Trust wall" with hardware that cannot be breached by software, eliminating any room for attackers. It is perfectly compatible with Zero Trust and is chosen as the "last bastion" of multi-layered defense. Infostealer malware reportedly sends information collected from the victim's computer to the attacker's computer in about a minute. Moreover, it cleverly bypasses communication monitoring. By the time you realize it, the attacker has penetrated deep within the internal systems, allowing them to cause real damage at any chosen moment. While humans are still making judgments, the attack quietly progresses, and the damage expands. If reconnaissance activities by viruses are tolerated, the next risk will directly hit operations. Therefore, communication lines can be cut off. Critical infrastructure, production facilities, IoT, SYS-LOG lines—once breached, these areas put business continuity at risk. A mechanism to seal off the "exit" to the outside, where information-stealing malware can transmit extracted data, is also essential. That’s OWCD. There is an explanatory video at the related link 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.
