Qosmos LibDevice 2.0 is an agentless, passive device fingerprinting solution for access networks. Available as an optional module (SDK) with the Qosmos ixEngine or Qosmos Probe, LibDevice 2.0 enables solution vendors to enhance their products with precise, detailed profiles of 50K+ types of devices across 24 consumer, enterprise, and industrial device categories.

LibDevice 2.0 combines breadth of coverage, embedded deployment, and non-intrusive technology, making it the ideal tool for boosting the device recognition capabilities of existing products, or creating entirely new device-aware products—quickly, easily and profitably.

LibDevice - Connected Device Visibility

Qosmos ixEngine extracts device metadata (a.k.a. fingerprints) from network traffic flows, and provides this data to the LibDevice module for device identification. If the device matches the profile of known devices stored in the local LibDevice look-up table, the device classification is then shared with the relevant networking or cybersecurity solution. If the device is new or unknown, the data is sent via a REST API to a cloud fingerprint repository for identification. The device classification (along with a confidence score for the identification) is then returned via the API. This classification data is then provided to the appropriate networking or security solution, and added to the local device look-up table.
