About Cynerio

Cynerio sells a platform that unifies security and operations across medical, IoT, OT, and IT assets. Axonius says the platform has native clinical workflows, AI-powered detection, and no compromise to patient care. Axonius describes the platform as purpose-built for hospitals, with native support for HL7, DICOM, RTLS, MDS2, and dozens of other medical-specific protocols.

The platform discovers and classifies every medical device with over 150 attributes per asset. The platform shows fleet-level risk scores, MDS2 and FDA data, and device utilization trends, all automatically prioritized for biomedical and security teams alike.

The platform automates alerting, ticketing, and enforcement using pre-built or custom incident response playbooks. The platform unifies CMMS, vendor catalogs, EHR/RTLS, and network telemetry into one up-to-date record per device so teams can prioritize fixes and replacements that reduce clinical risk and downtime.

Axonius says the threat detection engine correlates device behavior and alerts into clear, actionable summaries. Axonius for Healthcare integrates with NAC, firewalls, ticketing systems, and CMMS tools, bridging BioMed and SecOps. The platform covers medical, IoT, IT, and OT devices, unified and secured under one platform.

Isle of Wight NHS Trust increases cyber resilience with a 360-degree view of managed and unmanaged assets from ITHealth and Axonius. One customer statement says a Bedfordshire Hospitals team expects greatly reduced risk from medical devices once the risk reduction activities have been applied. North Lincolnshire and Goole NHS Foundation Trust reduced IoT risk and achieved DSP Toolkit compliance with Axonius. MarinHealth stops IoT device malware in its tracks and inspires a new Axonius product. One customer statement says the team knew it needed to segment the network to secure devices, and needed to see what was happening to segment effectively.
