Asimily Cyber Asset Defense Platform (IoT/OT/IoMT)

Asimily is a connected device security company based in Sunnyvale, California, founded by Shankar Somasundaram, who previously led IoT security at Symantec. It protects IoT, operational technology and internet of medical things devices that cannot run security agents, such as infusion pumps, imaging systems, PLCs, cameras and building controllers, for hospitals, manufacturers, utilities, ports and cities.

The Proactive Cyber Asset Defense Platform builds an inventory of all devices through passive traffic analysis, protocol queries and APIs, using lightweight Edge processors for distributed capture. It ranks vulnerabilities by real exploitability with MITRE ATT&CK analysis, simulates the effect of a patch, configuration change or segmentation step before rollout, and pushes segmentation policies directly to network equipment from Cisco, Aruba, Arista, Fortinet and Palo Alto Networks. Further modules cover threat response, configuration control, IoT patching and compliance.

• Inventory and visibility: Discovers unmanaged devices passively, by protocol or via API.
• Exposure management: Uses ATT&CK analysis to flag vulnerabilities that are exploitable on each device.
• Risk simulator: Compares the effort and benefit of a patch, configuration change or segmentation step.
• Segmentation orchestration: Generates policies from device behaviour in each network vendor's native format.
• IoT patching and configuration control: Manages manufacturer-approved patches, passwords and configuration drift.
• Compliance reporting: Supports HIPAA, FDA, NIST CSF 2.0, NIS2, NERC CIP and PCI-DSS.

A hospital group in Vietnam can inventory imaging systems and infusion pumps and isolate vulnerable devices without stopping care. A manufacturing plant can find exposed PLCs and cameras and push segmentation rules to its existing firewalls. An industrial park operator can monitor building management and security devices across tenants.

Security teams see every connected device, including unmanaged medical and industrial equipment, in one inventory. Fixes are prioritised by exploitability, and the site reports that customers typically remove more than 10,000 high-risk vulnerabilities in the first three months. Segmentation can be simulated before enforcement, reducing the risk of disrupting clinical or production systems. One manufacturer cut capture hardware costs from over 100,000 USD to about 15,000 USD using Edge processors.

Hospitals, factories and smart buildings now run thousands of connected devices that cannot be patched or protected with agents, and ransomware groups increasingly use them as entry points. In Vietnam and Southeast Asia, hospital digitisation and the spread of connected factory equipment raise the need for agentless device visibility and network segmentation.

Founded by Shankar Somasundaram (CEO) and Hithesh Nama, with an office in Sunnyvale, California, and contacts for Europe and the Middle East. Named Best in KLAS 2026 for IoT Security; the site also shows CRN and Deloitte Fast 500 recognitions. Founding year is not stated on the site.
