Dublin, July 23, 2025 (GLOBE NEWSWIRE) -- The "Data Diode Market Report 2025" report has been added to  ResearchAndMarkets.com's offering.

The data diode market size has grown rapidly in recent years. It will grow from $1.11 billion in 2024 to $1.27 billion in 2025 at a compound annual growth rate (CAGR) of 15.2%.

The growth during the historic period can be attributed to growing concerns over cybersecurity, a higher incidence of cyber threats, an increased need for industrial control systems (ICS) security, expanding regulatory compliance requirements, and a rising awareness of advanced persistent threats (APT).

The data diode market size is expected to see rapid growth in the next few years. It will grow to $2.23 billion in 2029 at a compound annual growth rate (CAGR) of 15%. The anticipated growth during the forecast period can be attributed to the adoption of Industry 4.0 technologies, rising data traffic and bandwidth demands, greater adoption of industrial cybersecurity solutions, the growing need for secure data transfer, and increased investments in the convergence of IT and OT systems.

Key trends expected during this period include advancements in technologies, progress in semiconductor and optical technologies, the emergence of 5G technology, and the development of advanced cybersecurity infrastructure.

The increasing concerns surrounding cybersecurity are expected to drive the growth of the data diode market in the future. Cybersecurity concerns involve the risks and challenges of safeguarding digital systems, networks, and data from unauthorized access, attacks, damage, or theft. These concerns have grown due to the rapid expansion of digitalization, which increases vulnerabilities, and the rise of AI-powered attacks, making it more difficult to detect and prevent cybercrime. A data diode enhances cybersecurity by ensuring one-way data flow, blocking external cyber threats from accessing critical systems while allowing secure data transmission.

For example, in April 2024, the Federal Bureau of Investigation, a US-based law enforcement agency, reported that Americans filed 880,418 cyber threat complaints in 2023, representing a nearly 10% increase from 2022, with potential losses exceeding $12.5 billion, a 22% rise from the previous year. As a result, the growing cybersecurity concerns are driving the demand for data diodes.

Companies in the data diode market are focusing on developing advanced solutions, such as data diode controller software, to enhance data protection and maintain unidirectional communication between networks. Data diode controller software is a security solution that enables one-way data transfers across isolated networks, ensuring strict data flow in one direction to protect high-security environments from cyber threats. For instance, in November 2024, Patton Electronics, a US-based company specializing in cybersecurity solutions for communication networks, introduced the Data Diode Controller Software (FPSW-DDC). This software facilitates secure, one-way data transfers over unidirectional data diodes, ensuring complete network isolation from cyber threats. It is designed for defense, intelligence, energy, and critical infrastructure sectors, supporting protocols such as SFTP, NFS, SMB, SMTP, MQTT, and OPC UA while automating real-time monitoring and logging across security domains. The software works with Patton's SFP Data Diode Modules or other physical data diodes, offering a user-friendly interface to manage secure data flows.

In December 2024, OPSWAT, a US-based cybersecurity company focused on protecting critical infrastructure, acquired Fend Incorporated for an undisclosed amount. This acquisition aims to enhance OPSWAT's cybersecurity solutions by integrating advanced data diode technology, boosting unidirectional gateway capabilities, and expanding its portfolio to better secure critical infrastructure from cyber threats. Fend Incorporated, a US-based company, specializes in the development and manufacturing of data diodes for data pipelines and cybersecurity applications.
