The only data diode featuring full management, configurable retransmission, and destination acknowledgment — all implemented 100% in hardware.
A data diode is the only acceptable interface when data leakage from a sensitive network to the outside world is not an option. Industry standards mandate physical unidirectionality — the reverse path is severed at the hardware level, not via software.
Absence of reverse TX/RX lines — a physical hardware guarantee.
Mandatory protection against compromising electromagnetic emanations.
Galvanic isolation partitioning the two security zones.
Legacy data diodes transmit packets over fiber with no way of knowing whether the data actually reached its destination or was corrupted along the way.
The entire operation is hardwired into the FPGA circuits. No shell, no system files, no background processes.
| Parameter | Competition | Our Diode |
|---|---|---|
| Software base | ✕Linux / custom kernel | Pure FPGA logic |
| 0-day vulnerabilities | ✕Inherited from OS | Immune (no OS) |
| Determinism | ✕Scheduler may delay | Constant & predictable |
| Attack surface | ✕Wide (services, daemons) | Restricted to silicon |
| Patch management | ✕Continuous, with downtime | Signed FPGA bitstream |
Packets leave the upstream board with hardware-enforced Forward Error Correction (FEC). No TCP overhead, no software network stacks.
The downstream FPGA decodes the FEC, automatically repairs errors, and holds the packet in its buffer until acknowledgment.
The receiving application confirms delivery. Upon a missing ACK, configurable retransmission is triggered, providing a true delivery guarantee.
The entire operation is implemented exclusively within the FPGA logic. With no processes, system files, or command interpreters, the software attack surface is completely eliminated.
Two physically separate FPGA boards with independent power supplies. Electrical compromise of one board cannot propagate to the other.
Active sensors protect against physical tampering. Any unauthorized attempt to open the chassis triggers the instant erasure of cryptographic keys and configuration data.
Advanced shielding against side-channel electromagnetic radiation leakage — a mandatory requirement for deployment in highly secure government and military environments.
Unlike legacy data diodes that rely on restrictive DIP-switches or offer almost no configuration at all, the DDF-10G/UNI exposes a comprehensive API for networking, monitoring, and policy management — all without introducing an operating system.
Dedicated management channel for secure IP, MAC, and VLAN orchestration.
Configurable retry limit per stream / application.
Multiple logical channels multiplexed over a single physical link.
Hardware counters: packet tracking, retry attempts, and corrected FEC errors.
Secure transfer of classified data to lower-trust analytics networks, maintaining absolute separation of the sensitive High-Side domain.
Streaming OT/SCADA telemetry to corporate IT networks with zero exploitable return paths. Energy, oil & gas, water, and transportation.
Replicating transactional data to back-office or analytics systems with zero risk of compromise.
Exporting medical imaging and patient data between networks with differing compliance tiers (such as HIPAA and GDPR).
Secure data downlink from high-integrity control systems to commercial processing platforms.
Exporting experimental results from an isolated laboratory with zero risk of Intellectual Property (IP) exfiltration.
Competitors only offer 'fire-and-forget' delivery. We deliver true end-to-end confirmation via a segmented ACK loop, configurable hardware retransmission, and live telemetry — all without sacrificing physical, hardware-level unidirectionality.
No Linux, no shell, no patch management. Completely immune to OS-level CVE exploits — the entire operation is hardwired into the FPGA logic.
Native 10 Gbps line-rate speed with constant, schedulerless latency. Hardware FEC repairs errors instantly, eliminating wasteful retransmissions over the physical fiber.
A data diode that operators don't just 'deploy and forget.' Instead, they actively monitor, configure, and audit it — all while fully preserving the hardware-guaranteed unidirectionality.
DDF-10G/UNI drops seamlessly between your networks without changing your topology, introducing a single point of failure, or exposing any software attack surface. We invite you to a 60-minute deep-dive technical session and a tailored Proof of Concept (PoC) directly on your production stack.
