Data Diode Solution

VCL Data Diode comprises two elements.

1. VCL-2726, Network Side (ORANGE) Element.
2. VCL-2726, Secure Side (GREEN) Element.

The Network Side (ORANGE) Element shall connect to the Secure Side (GREEN) Element through a single, one-way, transmit only optical fiber which shall only allow the ONE-WAY flow of data from the Network Side (ORANGE) Element to the Secure Side (GREEN) Element, thereby creating a ONE-WAY data path with Low-latency data transfer (<1 ms).

Such a design ensures physical and electrical separation between source and destination networks. This architecture eliminates external entry points, blocking intruders and malicious elements from accessing the data secured by the VCL Data Diode. By securing data flow with the VCL Data Diode, the protected data is secure from malware transmission, unauthorized access, and harmful changes to an organization's data.

Valiant's Data Diode finds it uses in applications and networks requiring highly secured protection of sensitive information, such as military, financial institutions, industrial design centres, utilities and critical infrastructure systems.

Valiant's Data Diode allows critical infrastructure organizations to transmit and store real-time data securely. This technology protects valuable information and networks from data theft, tampering, destruction, and human error, preventing significant potential losses.

The VCL Data Diode allows the data to flow in only one direction. This ensures one-way information flow from secure areas to less secure systems (or vice versa), without reverse access. VCL data diodes have two sections, that are physically separated: the "send" or the ORANGE section, which can only send data, and the "receive" or the GREEN section, can only receive data. This configuration guarantees one-way data flow and prevents reverse transmission.

The VCL Data Diode delivers a 1 Gbps data transfer rate for one-way communication. VCL-Data Diode is certified to EAL4+

Benefits of Using Data Diodes – Summary:

1. Enhanced Security: By physically blocking data from flowing back into the source network, the VCL Data Diode provides a high level of protection against cyber threats.
2. Regulatory Compliance: Many industries have strict regulations regarding data security and privacy. The VCL Data Diode helps organizations comply with these regulations by ensuring secure data transmission.
3. Reliability: VCL Data Diodes are not prone to failure compared to software-based data security solutions, providing a reliable means of securing critical data.
4. Prevention of Data Leakage: The VCL Data Diode prevent sensitive information from being exfiltrated from secure networks, thus protecting intellectual property and confidential data.

Hardware-Enforced protection – A summary of key features and functions of data diodes:

1. One-Way Data Transfer: The VCL Data Diode physically enforces unidirectional data flow, meaning data can only be transmitted from the source network to the destination network, but not the other way around. This ensures that any potential threats or malware cannot travel back from the destination network to the source network.
2. High Security: By preventing bidirectional communication, data diodes eliminate the risk of external attacks on the source network. This makes them ideal for protecting critical systems and sensitive data.
3. Hardware-Based Solution: Unlike software-based firewalls and other security measures, the VCL Data Diode may be used to enforce hardware-based data flow restrictions. This makes the network more robust and protected against software vulnerabilities and cyber threats.
4. Applications- The VCL Data Diodes may be used to protect:
• Industrial Control Systems (ICS): Used to protect control systems in power plants, water treatment facilities, and other critical infrastructure.
• Military and Defense: To store and protect sensitive military records and data.
• Financial Services: Used to securely store banking data, details of financial transactions and financial records.
• Health Care: To ensure secure storage of patient data and medical records.
5. Performance: The VCL Data Diodes are designed to handle high data throughput and can support various types of data, including video, audio, and large files. They are typically optimized for low latency and high reliability.
