When Firewalls Fail, Data Diodes Keep You Resilient

Built for Critical Systems That Cannot Be Compromised

Traditional Firewalls Are Not Enough
To Stop Modern Attacks

Zero-day exploits and misconfigurations can turn protection into exposure. The risk is rising:

1 in 3

organizations reported integrity or availability impacts from uncontrolled data transfers

~45%

of organizations in critical infrastructure reported an increase in cyber incidents

87%

of cyberattacks involve data exfiltration and/or encryption activity

63.9%

of organizations reported an increase in ransomware attacks targeting OT

Data Diodes Enforce One-Way Transfer by Design

A data diode is a hardware-enforced security device that allows data to move in one direction only, creating high-assurance 
segmentation between networks of differing trust levels. Unlike firewalls or software gateways, it reduces exposure by eliminating 
the conditions that enable backchannels and bidirectional flow. In critical environments where IT, OT, and cloud intersect, 
unidirectional flow is a resilience mandate.

Hardware-Enforced Segmentation

True one-way communication governed by the laws of physics, removing the return path and reducing backchannel access risk into critical networks.

Built for OT and IT Integration

Support for industrial and enterprise protocols plus integration into monitoring and analytics workflows, including tools like Splunk and AVEVA PI.

Resilience and Assurance

High-availability options, regulatory-ready certifications (for example EAL4+ and C1D2), and 24x7 support for mission-critical operations.

Select the Right Data Diode

Identify the best-fit diode configuration based on flow direction, protocols, and availability needs.
