  • ST Engineering Data Diode - Secured Data Transfer Gateway


ST Engineering Data Diode is a product designed and produced by ST Engineering Group and deployed by qualified and trained engineers from Singalarity to protect safety-critical systems and sensitive or proprietary data. It is a powerful tool to help your organization successfully eliminate potential cybersecurity risks.

ST Engineering Data Diode prevents data leakage and eliminates cyber threats by enforcing the one-way data transfer at both the physical and protocol layers, providing absolute protection from any reconnaissance and cyberattacks originating from outside the corporate network or any attempt to hijack or compromise the system from the inside.

What is ST Engineering Data Diode?

 ST Engineering Data Diode is also known as "Unidirectional Security Gateways" or "One-way Firewall", with a communication and data transfer mechanisms are implemented via an "air-gap" thereby ensuring guaranteed delivery, fault tolerance and scalability.

What is the “Zero-loss Capability” concept?

Most conventional file transfer network protocols operate as a “two-way communication” to ensure data packages are not lost during transmission. As data diodes enforces a “one-way communication", protocol, preventing compromises to data integrity is an issue as it is difficult to validate data integrity and detect potential loss in data.

  • With an “air-gap” in the design architecture to provide assurance, ST Engineering Data Diode ensures 0% data loss in transmission; throughput is maintained at levels:

  •         + Up to 20Gbps Unidirectional Media Transfer Rate 

  •         + 500 Mbps

  •         + More than 225 GB per hour

        + More than 5.4 TB per day

Advanced and Proven technology is implemented at the data transfer layer to ensure “zero-loss capability” and check data integrity respectively.

  • “Zero-loss capability”  is a proprietary technology to ensure the safety and integrity of the data transferred.

*No more than 1 File lost in 5 Million Files Transfer

ST Engineering Data Diode requires no additional proxies or virtual machines to be installed on external hardware.

ST Engineering Data Diode also has a patent-pending file loss detection capability which allows users to be alerted in an event of file loss across the data diode.

Furthermore, ST Engineering Data Diode’s modular design allows customers to select components suited to their operations.
