The most mature usage of data diodes spans into the security sector. These diodes can enable secure communication of data even when data flows from unsecure to highly-secure environments, and vice versa. In addition to this, data diodes also offer protection against data breaches and compromise of critical infrastructure across corporate networks.

As industries become increasingly interconnected, data diodes are playing a vital part in creating an environment for effective cross-industry collaboration and data exchange. The technology could also foster improvement in the national security capabilities of nations.
