Is the data source safe? The data diode OWCD "Data Secure Link" can prevent intrusions by restricting communication in one direction.

One-way communication restriction device data diode "OWCD" The recognition among infrastructure engineers and security engineers has been increasing. You are already aware of it, right? The simple structure of the data diode, which focuses solely on physically directing communication in one direction, is well-supported. However, relying solely on that capability may not be sufficient for practical use. Therefore, we have prepared a lineup to meet various communication needs, including converting bidirectional communication protocols to one-way, protocol conversion according to the circumstances of the receiving side, such as the Internet, and even enhancing value through the collection and analysis of IoT information. Among them, one product is the data diode OWCD "Data Secure Link." It is absolutely not allowed for anything to enter internally, and it can be utilized to ensure the security of our customers. As digital transformation (DX) progresses, the challenges of operational management increase along with 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 and ensures safe and secure operations. There is a video introducing the principle; please check the related link below.

Inquire About This Product

basic information

There are various setup methods. 1000Mbase-T (RJ-45) connection is standard. Effective value (standard setting) is 300Mbps. The device has a built-in Windows OS. It is equipped with whitelist software as its own antivirus measure, so you can use it with peace of mind. - Supports TCP, SMTP relay, and OPC UA. - Also supports HTTPS and MQTT. * For file transfer, please use the sibling product "File Secure Link." * For UDP and SNMP trap support, please consult us. In addition to this, models that support low communication bandwidth and models that combine with separate PCs are also available. * Measures against the shortage of specialized personnel: Progress is rapid and accumulates exponentially, and the shortage persists... * Measures against resource shortages: Ultimately, if you introduce various services, costs can add up... * Measures against low crisis awareness: Even if it is said that operations could cease, it is still... It is no longer possible to prevent intrusions. Multi-layered defense is essential to prevent the expansion of damage. Physical defense has a significant effect on countermeasures and plays an important role in multi-layered defense. Please contact us through the related links above.

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. Last year, we faced the onslaught of ransomware, and it will likely continue this year. Even zero trust has been breached. We cannot remain defenseless against ransomware forever. Let's 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 sends 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 also supports HTTPS and MQTT. In addition, functionality can be added to both the sending and receiving sides. - It can be equipped with the ability to collect data directly from sensors or PLCs and send it via OPC UA, HTTPS, or MQTT. - Database recording, web-based data visualization, and direct integration with customer service dedicated terminals are also possible. - In the case of database integration, there is also the option of file transfer if the data is temporarily converted into a file. - We accept consultations regarding DIN rail mounts or wall mounts for integration into control panels, including communication effective values. - Functions for analysis and detecting unusual changes can also be implemented. It prevents intrusions from communication routes far more robustly than a password lock. It is used not only for production equipment DX and IoT but also for secure communication in government agencies and other organizations. Please contact us via 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 through 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. Starting with support for communication protocols, it has the capability to respond to various applications and can also be customized. Please make use of it.
