Ruggedized Data Diode Market Trends

Growing Awareness of Network Segmentation to Emerge as a Key Market Trend

Network segmentation means dividing a computer network into smaller sub-networks so as to ensure that the security breach will be confined to an isolated segment and restrict access by potential attackers to the entire network. In this regard, ruggedized data diodes are important since they provide secure data transfer between segments without unauthorized access or data believability; they also create a physical barrier in the network, allowing data to flow in one direction only. This is of great advantage in cases where confidential information has to be transmitted across different divisions of an organization. Thus, this trend could increase the market share.

MARKET DYNAMICS

Market Drivers

Rising Cyber Security Threats to Aid Market Growth

The merging of IT and OT systems has exposed weaknesses in essential infrastructure due to the increasing number of advanced cyber threats, including ransomware and malware.
