Is data transmission safe? AI has surpassed software-based security. "Data Secure Link" physically restricts communication to one direction.

One-way communication restriction device data diode "OWCD" In response to the inability to implement zero-trust security based on the premise of "no connections," the simple structure of the data diode, which focuses on physically restricting communication flow to one direction, is gaining support. However, relying solely on boundary restriction capabilities is insufficient for practical use. Therefore, we are advancing a lineup of models that respond to various communication needs, including protocol conversion tailored to the recipient's circumstances, such as directing bidirectional communication protocols to one direction, as well as collecting and analyzing IoT information to enhance value. Among these, we present the data diode OWCD "Data Secure Link." It ensures that no internal access is allowed, thereby enabling utilization suitable for securing customer security. As digital transformation progresses, the operational management becomes increasingly challenging alongside the increase in communication volume. We encourage you to utilize the data diode OWCD "Data Secure Link," which allows for easy and clear use with minimal running costs, ensuring safe and secure operations. There is a video introducing the principle; please check the related link below.

basic information

Data diodes vary by company, but OWCD improves deployability by separating the air gap section from the PC that handles communication protocols and other processing. There are various installation methods. A 1000Mbase-T (RJ-45) connection is standard, with an effective value (standard setting) of 300Mbps. A PC is required for the converter, but a whitelist-type antivirus software can be provided as a security measure. - Supports TCP, SMTP relay, and OPC UA. - Also supports HTTPS and MQTT. * For file transfer, please use the sibling product "File Secure Link." * Please consult us regarding UDP and SNMP trap support. * Measures against the shortage of specialized personnel: Progress is rapid and accumulates exponentially, leading to a persistent shortage... * Measures against resource shortages: No matter how much money you have, it’s not enough if you introduce various services... * Measures against low crisis awareness: Even if told operations could cease, it’s hard to believe... We can no longer prevent intrusions; multi-layered defense is essential to prevent the expansion of damage. Physical defense is highly effective and plays a crucial role in multi-layered defense.

Price information

Focusing on the basic model, - We want to support multiple communication protocols. - We want to incorporate our own service programs. - We would like to provide a separate computer. Please consult us for customization towards your operations. Also, feel free to consult us about communication and system integration within your network. The threat of ransomware is only increasing, with AI utilization enhancing both accuracy and attack speed. Even with zero trust, it can be breached as long as there is a connection. Let's add reliable boundary restrictions and avoid operational shutdowns with multi-layered defenses. Please contact us through the related links above.

Applications/Examples of results

The sending computer receives data and immediately transmits it to a receiving computer in a different security zone via the data diode OWCD. - It supports TCP, UDP, SMTP relay, OPC UA, and SNMP traps. - It can also support HTTPS and MQTT. In addition, functionality can be added to both the sending and receiving sides. - It can include features to collect data directly from sensors or PLCs and transmit it via OPC UA, HTTPS, or MQTT. - Database recording, web-based data visualization, and direct integration with customer service-specific terminals are also possible. - In the case of database integration, file transfer is an option if the data is temporarily converted to a file. - We also accept inquiries regarding DIN rail mounts or wall mounts for integration into control panels, including communication effectiveness values. - Functions to analyze and detect unusual changes can also be implemented. It prevents intrusions from communication routes far more robustly than a password lock. OT: In addition to production equipment DX and IoT, it is also used for secure communication in government agencies and other organizations. Please contact us through the related links above.

Detailed information

A data diode is a device that restricts communication to one direction. The Data Diode OWCD prevents unauthorized access or data exfiltration via viruses by using a route for sending files. We have established features to better utilize this characteristic. It is a "Data Secure Link" that connects computers that cannot see each other due to different security management zones. Even those who are not communication security experts, such as firewall or router users, can easily configure it. We started with support for communication protocols and equipped it with the ability to respond to various applications, allowing for customization as well. Please make use of it.
