Dublin, July 06, 2026 (GLOBE NEWSWIRE) -- The "Data Diode Market by Form Factor, Application Area - Global Forecast to 2031" has been added to ResearchAndMarkets.com's offering.

The data diode market is projected to expand significantly from USD 0.56 billion in 2026 to USD 0.77 billion by 2031, achieving a compound annual growth rate (CAGR) of 6.6%. This growth is attributed to the rising occurrences of ransomware attacks on industrial and critical infrastructure environments. Such cyber threats highlight the increased need for operational system security, network isolation technologies, and measures to prevent unauthorized access.

Market Segmentation by Verticals

In 2026, the government and defense segments are anticipated to secure the largest market . This growth is driven by the deployment of data diode solutions by defense and government bodies aiming to safeguard classified networks and critical defense infrastructures against cyber espionage and state- attacks. These solutions facilitate secure one-way data communication, essential for the protection of mission-critical defense environments.

Heightened investments in cyber warfare preparedness and the need for secure cross-domain communication reinforce the demand for data diode technology. Furthermore, defense agencies are prioritizing strategies like network segmentation and zero-trust security, which boost data diode adoption in national security.

The software segment is expected to exhibit the highest CAGR during the forecast period. This growth is due to a surge in the need for flexible and centrally managed unidirectional communication solutions. Industries are rapidly integrating software-defined data diode platforms to facilitate protocol replication, remote monitoring, and cross-domain communication. The increasing trend of IT-OT convergence and demand for cost-effective cybersecurity solutions is further driving this segment.
