RubyComm — full profile (machine-readable)

RubyComm develops tailored operational technology (OT) cybersecurity solutions for industrial and mission-critical environments where standard security products are difficult to deploy, technically unsuitable, or prohibitively expensive. The company protects legacy and modern operational assets across manufacturing, critical infrastructure, healthcare, energy, and smart buildings. Its solutions are designed for systems that cannot be easily patched, replaced, interrupted, or modified without affecting safety, availability, or operational performance. At the core of RubyComm’s approach is inline, hardware-enforced protection deployed directly in the communication path of the protected asset. This creates a dedicated security boundary around critical equipment without requiring software installation or changes to the asset itself. Rather than applying a one-size-fits-all product, RubyComm combines compact security appliances, asset-level protection, network segmentation, secure communications, monitoring, and customized security architecture. This enables organizations to protect specialized equipment and operational processes while minimizing deployment complexity and disruption. RubyComm’s approach addresses common barriers to OT cybersecurity, including legacy systems, proprietary protocols, limited internal expertise, complex operating environments, and the high cost of conventional enterprise solutions. The company works closely with infrastructure operators, industrial organizations, medical equipment providers, energy companies, smart-building operators, and equipment manufacturers to deliver practical and scalable protection. Founded in Israel with a presence in the United States, RubyComm is focused on making advanced OT cybersecurity accessible to organizations and equipment manufacturers that require effective protection without redesigning their existing operational environments.
